Description

Reflector effect with artificial cloud technology: With its three-dimensional curtain feature, artificial cloud technology provides protection from radiation frost damage that occurs during clear and windless weather. It maintains the current temperature of the land and reflects the radiation energy (heat) back to the ground. It acts as a thick blanket drawn over the field protecting the heat of the ground.

Anti-freeze effect with moisturizing oil vapor: The sprayed artificial cloud is the vapor form of an oil solution. It temporarily creates a very thin layer of oil over the blossoms. Penetrating between water molecules that tend to crystallize and freeze, it increases resistance to cold and provides an anti-freeze effect. It also delays and prevents conduction damage caused by the red-colored radiation energy occurring at sunrise.

Protection effect with inversion: The cold air mass that causes inversion is heavier than the atmosphere and tends to sink toward the ground. The sprayed artificial cloud curtain is lighter than the atmosphere and tends to rise upward. Due to the physical principle that cold and hot air cannot mix, the artificial cloud curtain prevents the cold air mass accumulated over the land from descending to the ground on the crops.

Other applications:
Thermal fogging machines can also be used for pest and fungus control. For pests that become active in hot weather and are difficult to combat—such as red spider mites, mealybugs, aphids, psyllids, codling moth, tuta, whiteflies, thrips, gray mold, powdery mildew, leaf spot disease, and others—thermal fogging machines offer allows the operator to save money and time. Oil-based spraying is 12 times more effective compared to water-based spraying and can reach much longer distances. Since there is not a single spot left untouched by the smoke particles, contact-effect pesticides can easily reach and neutralize fungal diseases or pests. This increases both the harvest amount and quality of crops.

Frequently Asked Questions ;

What is the protection capacity?

The protection capacity of the Ultra Fogger device should be 20 ha in calm weather and 10 ha in windy weather.

Why is capacity important?

In fighting agricultural frost, time is of the essence. When the air temperature is around 1 °C, every point of the land must be covered with a thick layer of smoke within 30 minutes. If a thermal fogging machine is used on an area beyond its capacity, sufficient fog density cannot be achieved; the smoke becomes sparse and the protective effect significantly decreases.

Smoke can remain in the air for up to 6 hours in fully closed greenhouses; in calm open fields, this duration is around 3 hours on average. However, over time, the density of the smoke decreases. Therefore, even in greenhouses, it is recommended to fog again every 3 hours to refresh the density.

Conditions in open fields are more sensitive. Even the slightest wind can disperse the smoke, reducing its effect or carrying it to another area. Therefore, each machine must be able to create a dense and thick artificial cloud curtain within half an hour in the area it is responsible for/ parcelled for. Because the thicker and more uniform the smoke, the higher its protection against frost damage to the blossoms.

What temperature difference can the machine achieve?

How Thermal Fogging Protects Against Agricultural Frost

Thermal fogging machines are not heaters — they don’t raise the surrounding air temperature. Instead, they protect crops by preserving the heat that’s already there.

Think of them like a blanket on a cold night: a blanket doesn’t create heat, but it traps your body warmth and keeps the cold air away. Similarly, a thermal fogging machine creates an “artifical cloud” that reflects plants’ and ground’s own heat back to them.

The artifical fog also delays ice formation in two additional ways:

Antifreeze effect: A thin oil-based coating on flowers stops water molecules from clumping into ice crystals, so even at –10 °C, frost won’t form.
Inversion effect: It is already explained that the artificial cloud acts like an emergency aliminium foil blanket, reflecting thermal radiation back toward the plants and slowing cooling. Inversion effect: as in the law of physics, the lighter artificial cloud rises and pushes away the heavier cold air which tries to sink on the plants. The fog curtain works asa shield, prevents the cold air from reaching and damaging the crops by pushing it away.

Note that most damaging frost in agriculture isn’t caused by low air temperature alone, but by radiation frost — happens on windless and cloudless sky. In such calm nights earth’s heat escapes upward and the ground cools rapidly. Wind and clouds help prevent frost:

Wind stirs warmer air and cold air, prevents cold air from settling above the plants.
Clouds act like a blanket, reflecting heat back down.

One way to picture this is with a cement mixer: if the drum stops, the cement mixture settles and hardens; if it keeps turning, the contents stay mixed and workable. In the same way, wind keeps air moving and prevents extreme cooling at crop level.

Another example is that it is often observed that frost does not form and flowers are not damaged during snowfall. In short, cold air or snow is not the actual cause of frost. Although subzero temperatures create a suitable environment for frost formation, the real cause is cloudless and windless static air conditions. In such weather, water molecules in the atmosphere condense and turn into ice crystals. At sunrise, the high radiation (heat) in the red wavelength range (700nm) rapidly contacts the flower surfaces covered with ice crystals. During this contact, a conduction effect occurs, and plants suffer the most serious damage at this stage. The sudden heat transfer through conduction burns the flower tissues in the ice crystals and causes permanent damage. The artificial cloud curtain created by thermal fogging machines prevents the high heat of the red light at sunrise from directly contacting the flowers, and also acts as an antifreeze by delaying heat transfer (conduction) and preserving the flowers.

Details on the conduction effect can be found in our upcoming articles or information booklets.

What are the advantages compared to frost fans, sprinklers, straw and tire burning, and other fogging machines?

Frost Fans:

Frost fans can provide protection in moderate frost conditions, up to –4°C. However, when temperatures drop below this level, frost fans lose their effectiveness. Frost fans work by mixing warm and cold air, creating molecular movement and air circulation in the air mass. This produces a limited heat transfer that aims to reduce frost damage.

When temperatures fall below –4°C, however, there is no longer enough warm air available to mix, making it impossible to protect flowers and fruit tissues. In such conditions, operating the fans can actually convert radiation frost (calm air frost) into advection frost (windy frost), which may cause more burning and tissue damage to crops.

Frost fans are also very expensive. Unit prices start at around €30,000, and a single fan can protect a maximum of 5 hectares (50 decares). To protect a 20-hectare area, four fans are required, bringing total equipment costs to about €150,000, excluding site preparation.

Additionally, due to safety protocols, frost fans automatically shut down under even light wind conditions to protect themselves. Installation is another major disadvantage: the system requires a strong electrical infrastructure or a powerful generator, which means extra costs and time for site works, cabling, and infrastructure. In rented land, such investments are often non-recoverable, creating a serious economic and operational disadvantage.

Sprinkler (Irrigation) Method:

The irrigation method can provide some protection in moderate frost, down to –4°C. However, in severe frost below this range, its effectiveness drops sharply.

At –6°C and lower, instead of protecting flowers and fruit, irrigation can increase frost damage, causing burning and death on branches and tree surfaces.

One of the most critical weaknesses of this method is the risk of power cuts, water interruptions, or pump failures. If irrigation stops suddenly, the wet surfaces freeze much faster and more deeply, which can result in the complete loss of branches and young trees. For this reason, irrigation is considered a high-risk frost-protection method.

Burning Straw or Tires

Using straw or tire burning to fight agricultural frost is labor-intensive and logistically difficult. It requires serious preparation in advance and often leads to delayed response.

This method produces smoke by direct combustion. Fire does not warm crops in a controlled way to create beneficial evaporation; instead, it breaks down the material at a molecular level and produces dry, fine-particle smoke. Straw and tire smoke consist of micronized particles about 1 μm in size, similar to cigarette smoke.

Because of this small particle size, the smoke drifts away quickly and does not stay suspended over the field. Since it is dry, it has no anti-freeze effect and cannot form a thick insulating layer capable of retaining heat.

By contrast, our thermal fogging machines do not burn the liquid. They heat oil-based fluid in a controlled way, producing a moist, dew-like vapor with a strong anti-freeze effect. The fog particles range from 1 to 100 μm, allowing the fog to stay suspended at different heights and form a dense, three-dimensional artificial cloud layer.

Because of the larger particle size, this artificial cloud forms a much thicker and more effective barrier than straw or tire smoke, trapping radiation (heat) far more efficiently. While straw or tire smoke acts like a thin sheet, the fog produced by our machines works like a thick blanket, providing far superior frost protection. The denser, thicker and consisting different micron sized particles the artificial cloud layer is, the higher the success rate against agricultural frost.

Other Smoke Machines or Homemade Systems:

Some farmers attempt to produce smoke by dripping diesel fuel into a tractor exhaust. This method is technically incorrect and highly risky. Fuel or oil in the exhaust causes carbon buildup and lubrication failure in pistons, rings, and cylinder walls, leading to rapid engine wear. In practice, tractors using this method often become unusable within two years.

The oil flow that can be fed into the exhaust is technically limited to about 20 liters per hour, which is far too low to create a smoke density and particle concentration sufficient to form an effective frost-protection layer.

Furthermore, exhaust heat does not vaporize the oil under proper conditions, so the resulting smoke is dry, not moist. Dry smoke has no anti-freeze effect and provides no real protection.

LPG-powered or low-quality thermal foggers also fail to produce effective smoke. LPG systems cannot operate in low temperatures because LPG tends to freeze around –1°C, making frost protection impossible. Low-quality thermal fogging machines only produce visible smoke, but not a functional artificial cloud layer. Not all smoke provides protection — dense appearance alone is not enough. If the particles are too small and dry, radiation frost protection is impossible.

Requirements for Successful Frost Protection:

For effective agricultural frost protection, the following are essential:

Vaporizing the oil at the correct temperature range without burning
Spraying the vapor in a moist (dew-like) state, without over-heating
Producing particles of the proper micron size
Creating a dense and thick artificial cloud layer

The higher the oil vaporization capacity (flow rate) of a thermal fogging machine, the greater the protection it provides.

Our thermal fogging machines provide three layers of protection:
reflector effect, anti-freeze effect, and inversion effect.

White Fog machines protect crops fully down to –7°C in calm conditions, and provide partial protection even at –10°C. By increasing the number of machines, reducing plot size, and using suitable fogging fluids, the success rate can be increased even further.

Does it provide guaranteed protection?

If the machine is running and fogging, it means it has successfully performed its task. However, successful frost protection depends not only on the machine’s operation but also heavily on weather conditions such as temperature, wind speed, and the operator’s technical and practical knowledge. Protection is easily achieved in light frost conditions between 0 °C and -2.2 °C or moderate frost between -2.2 °C and -4.4 °C. However, in severe frost events below -4.4 °C, the success rate may decrease. Saving 60% or even 100% of the crops depends on the number of machines used, the size of the parceled area, and the chemical properties of the oils applied.
On nights when temperatures are expected to drop below -4 °C, it is recommended to use two different fogging liquids:
Before and during frost, use Vegetable Glycerin (which has a strong anti-freeze effect but produces thinner smoke), and
Before sunrise, before the red light spreads, use AV fogging oil, SR fogging oil (which produces denser white smoke but has a lower anti-freeze effect). In summary, the anti-freeze effect of vegetable glycerin vapor combined with the reflector effect of the bright white artificial cloud curtain created by AV or SR fogging oils allows for saving more crops and provides maximum benefit at temperatures below -4 °C. The success rate varies depending on the operator’s technique and application knowledge. Therefore, it is strongly recommended to utilize the theoretical and practical guides prepared by our company and to strictly follow our application instructions. Otherwise, it may take at least 2 years for an operator to gain sufficient experience.

What kind of liquid should I use for the fog?

✅ Vegetable glycerin; Used for anti-freeze effect both in greenhouses and open fields. Vegetable glycerin is viscous and should be diluted with 25% deminerilized water (pure water) to become fluid. It must be noted that the smoke density and whiteness (reflectivity) produced by vegetable glycerin oil is less compared to other oils. However, it is preferred for its anti-freeze property rather than reflector effect. White Fog supplies this formulation of vegetable glycerin in 1 ton IBC tanks to enhance performance in agricultural frost protection and to help agricultures. It is a custom-developed blend that provides enhanced antifreeze performance compared to standard glycerin. The vegetable glycerin that is supplied by our company is ready to use, requires no additional mixing or preparation by the user. This special formulation includes approximately 20% demineralized water, along with natural components such as glucose. These natural additives strengthen the glycerin’s performance and maximize its antifreeze effect. This special glycerin mix is supplied in 1-ton IBC tanks only.

White Fog’s special glycerin mix contains;
Vegetable Glycerin: Forms an ultra-thin, invisible protective oil layer on flowers and crops, lowering the freezing point, protecting cell sap from frost.
Demineralized Water: Added at approximately 20% to transform the vegetable glycerin from gel into a free-flowing liquid suitable for spraying.
Glucose: Increases the concentration of cellular fluids and delays crystallization, helping plant cells resist freezing.
Other Natural Components : In addition to the ingredients listed above, the formula contains other natural compounds supporting the antifreeze performance.

✅ AV fogging oil; Used only in open fields for reflection effect, not recommended for greenhouse applications. Due to its longer molecular chain structure compared to other oils, it moves slower and provides longer protection over the field. It produces bright white smoke maximizing the emissivity(reflection) benefit. We recommend obtaining enough from our company to fog for at least 1-2 hour during red light appears at sunrise. AV fogging oil can be supplied from our company either in 1-ton IBC tanks or in 21-liter metal cans.

✅Diesel fuel; For users who do not wish to use AV thermal fogging oil (aviation oil) or who do not have sufficient time to procure it, diesel vapor can be used as an alternative reflective fogging fluid. This method should be used only in open fields and is not recommended for greenhouses. Compared to AV fogging oil, diesel has a shorter molecular chain structure. For this reason, the sprayed fog drifts more quickly and remains suspended over the field for a shorter time. However, after AV fogging oil, diesel produces the brightest and whitest smoke, providing high emissivity (reflective) performance, and it is also easy to obtain. It is recommended to use it for 1–2 hours around sunrise when red radiation becomes visible.

✅ LP fogging oil; This oil has been developed only for greenhouses, supplies both antifreeze protection and reflection (emissivity). It is not recommended for open-field applications. Because frost protection in open fields is more challending and involves a higher risk of loss, the use of the stronger and higher-performance oils mentioned previously is recommended for the outdoor fields instead. LP fogging oil is an advanced-grade oil that produces a dense, bright white fog with high emissivity (reflective performance) and, thanks to its ability to penetrate water molecules, also provides an antifreeze effect. After application, the oil film leaves no odor and no residue. Safety MSDS and PDS technical documents are available for this product. The fog generated in greenhouses can remain suspended in the air for up to 6 hours; however, it will gradually settle and dilute over time. For this reason, re-fogging every 3 hours is recommended to maintain optimal density. To achieve an effective protective volume, 1 lt of LP fogging oil per 1,000 m² (1 decare) of greenhouse area is recommended.

Greenhouse Application Recommendation for Agricultural Frost Protection;
Layer 1 – 23:00 (11:00 PM)
-Fog the greenhouse using 5 liters of LP fogging oil for 5 decares (5,000 m²) of greenhouse area.
-After fogging, close the greenhouse.
Layer 2 – 02:00 (2:00 AM)
-After 3 hours, apply a second fogging layer using another 5 liters of LP fogging oil.
–Close the greenhouse again after application.
Layer 3 – 05:00 (5:00 AM)
If the fog density has decreased or additional protection is needed because frost continues, apply a third fogging after another 3 hours, again using 5 liters of LP fogging oil. Close the greenhouse after fogging. And approximately 1 hour after sunrise, once the ambient temperature has increased, open the greenhouse doors to ventilate the greenhouse.

IMPORTANT INFORMATION:

If temperatures in open fields are expected to drop to a maximum of –4°C, the vapor of diesel fuel alone or AV fogging oil alone can provide effective protection. If temperatures are expected to fall below –4°C, better results can be achieved in open fields by using a combined application of vegetable glycerin and AV fogging oil, which helps save more crops.

At temperatures lower than –4°C, during the night, first vegetable glycerin vapor must be sprayed over the field benefitting from its antifreeze properties. Vegetable glycerin vapor will form an invisible oil film around the flowers. It will penetrate between the two hydrogen bonds in water molecules and, thanks to its antifreeze properties, will delay and prevent ice formation.

Then, at sunrise, we recommend spraying AV fogging oil vapor. The artificial cloud curtain should be bright white, dense, and thick, blocking as much of the sun’s red radiation as possible. The red light emitted by the sun at sunrise (700 nm wavelength) is the longest and most intense radiation wavelength. The term radiation frost comes from this phenomenon. Even if the flowers have managed to stand the cold during the night, the greatest damage is caused by the red light emitted by the sun. This is called conduction damage (heat transfer). Cold flowers, lightly covered with ice, are suddenly exposed to red light (high heat), causing them to burn rapidly, their surfaces to be damaged, and their cell sap to be lost.

If, during the night, the flowers are coated with a thin oil film of antifreeze vegetable glycerin, and during radiation frost at sunrise in windless, cloudless conditions a dense artificial cloud curtain is created using AV fogging oil (aviation oil) or diesel, a protective artificial atmosphere above the plants is formed and conduction-based frost damage does not occur.

A simple example of conduction damage is as follows: place a fish in a hot pan without adding oil. Due to rapid heat transfer (conduction), the fish will quickly burn and stick to the pan, damaging its surface. If oil is added, a thin oil layer forms between the hot pan and the cold fish, preventing direct heat contact and delaying burning.

During agricultural frost, the surface of the flowers is very cold. The thin oil layer formed by vegetable glycerin around the flowers prevents the high heat from the rising sun from being transmitted directly to them. The oil layer acts as a delay between the flowers and the sunlight. This antifreeze layer slows the transfer of heat to the flower surface and prevents damage from sudden heat transfer (conduction). The reason for choosing the whitest smoke and forming a thick artificial cloud curtain at sunrise is to delay sunlight from reaching the flowers as much as possible.

IN SUMMARY:
Vegetable glycerin sprayed during the night creates an antifreeze effect on the flowers, delaying cooling and freezing as much as possible. At sunrise, AV fogging oil (aviation oil) or diesel vapor, with its bright white smoke, provides a reflective effect that delays the sun’s heat from reaching the flowers too quickly. With this technique, both the cooling phase and the warming phase are slowed in a controlled manner. By delaying both processes, a double protective effect is achieved, minimizing radiation frost damage and maximizing protection.

What is the daily cost?

The service life of the machine and equipment is 15 years. Excluding machine depreciation costs, the only cost will be incurred during a frost night is fogging fluid and engine’s fuel. The daily cost varies depending on the duration of the frost event. Radiation frost can last approximately 2 hours in some provinces and up to 10 hours in others. Therefore, users should calculate costs based on the frost duration in their own region using the information below. In the calculations below, the highest-performance oils and the longest agricultural frost scenario (10 hours) were considered, and an example cost was created based on this 10 hours of operation. You can easily adjust your calculation proportionally according to the frost duration in your area (e.g., 1/10 if your frost lasts 1 hour).

When should fogging start?

During radiation frost nights, the wind does not suddenly stop completely and the temperature does not drop abruptly. First, the temperature begins to decrease slowly in intervals. Then, sharp drops of 3-4 degrees in temperature are observed. If after 1-degree drops, a sharp 3-4 degree drop occurs, it is certain that a radiation frost event will happen shortly.

Meteorological agricultural frost warning systems provide information for 5-day periods with frost risk. On risky nights, vigilance is kept and necessary protective measures are taken. When the temperature drops to +1 degree and wind speed falls below 10 km/h, the frost fight should begin.

There is no exact start time for agricultural frost; it is entirely relative. Sometimes it can last 1 hour at sunrise, sometimes it can continue for 10 hours starting from 1:00 AM. Therefore, temperature and wind speed data are very important to estimate the frost start time.

If there are smart meteorological information systems in the field, temperature and wind speed are monitored every 30 minutes. If after a gradual temperature drop, a sudden 3-4 degree decrease is observed, it is confirmed that agricultural frost will occur shortly and fight against frost should start.

Farmers without smart meteorological warning systems use traditional methods such as observation with a portable thermometer and burning straw or tires in risky areas to observe the smoke. If the smoke no longer floats or disperses over the field, it means an inversion layer with very cold air has formed. In such cases, frost fight with ULTRA FOGGER should start immediately. Instead of relying on straw or tire smoke, wind speed can also be observed by hanging a flag or streamer about 3-4 meters high.

When wind speed falls below 10 km/h and temperature reaches +1 degree, artificial fog with ULTRA FOGGER should be applied to prevent further temperature drops and to preserve the existing heath (if your field is large start even earlier +2 degrees). The risk begins the moment the wind blows at 10 km/h. At this stage, the temperature may suddenly drop to -1 degree and wind speed may suddenly fall to 0 km/h. Starting protection early in such situations is a great advantage.

With the help of light wind, artificial oily fog is sprayed over the entire field, surrounding the flowers with an oil layer. This serves as anti-freeze effect. When wind speed drops to zero, the protection capacity of the artificial cloud doubles. The artificial cloud curtain stays suspended above the crops, and acts like a blanket providing protection through heat reflector effect.

In the above graphic, published by the meteorology center on 30th of March, we see a sudden decrease of heat below zero degrees, where frost happened.

In above graphic, we see that in the night of March 30th at 22:00, the temperature was 7 degrees and dropped to 2/3 degrees by 23:00 and 00:00. Such a sharp drop in about 1 hour is a warning of frost.

And here we observe the wind speed on another night. While at 21:00 the wind speed was 14km, at 00.00 the wind speed became 0 km. This shows that frost formed that night.

Does the fog leave any residue on crops?

Even if you want, smoke cannot leave residues nor prevent pollination. Since the vapor form of oil is sprayed, the created oil layer lasts up to 12 hours at most. Afterwards, it evaporates and completely disappears by mixing into the atmosphere. The formation of a 12-hour oil layer positively contributes to the protection during agricultural frost. The thin oil layer created is microscopic in size and cannot be seen with the naked eye. Because the smoke particles are very small, they cannot clog the pollen tube or prevent pollen from reaching the ovary.

How dense should the fog be?

A dense white colored artificial cloud should be created over the land. The dense white colored artificial blanket increases the emissivity (radiation reflection rate), helping to retain the warm heat on the ground surface. If one tries to protect the land with a sparse thin and see through smoke, as when straw or tire is burnt, this indicates that the protection is very low, radiation is not being sufficiently reflected to earth, and the earths heat is escaping into athmosphere.
If the human eye cannot see behind the smoke curtain, it is opaque and dense, it means a successful radiation reflection (reflector effect) is achieved.

Is it necessary to constantly move around the field?

The wind speed does not suddenly stop but gradually slows down to around 10 km/h and the temperature is +1 degree, at this stage fogging must be started. Even if the artificial cloud curtain effect is not utilized, the anti-freeze effect will still be beneficial. This is because there is a risk of a sudden 3-degree drop, and waiting for zero degrees or wind speeds below 1 km/h may result in “starting the frost combat too late”.
Fogging should be done in the direction of the wind. Fogging is performed by moving back and forth at a 90-degree angle to the wind direction, and with the help of a light breeze, the land is quickly and easily covered with the fog curtain. In windy conditions, this work area should not be abandoned. Fogging should not be done in other parts of the land. Doing otherwise increases the risk of flower damage. However, when the wind completely stops and no wind assistance is available, the operator should quickly move around other areas of the land and manually distribute the fog that the wind no longer spreads, saving time and protecting a larger area.
Remember, when the wind is blowing, protection capacity is halved. Once the wind stops, capacity is doubled.

How is pest control application done?

Thermal fogging machines offer up to 12 times more efficient spraying compared to garden sprayers. These machines perform oil-based spraying, while sprayers apply water-based pesticides. Since water-based pesticide droplets are larger, they quickly fall to the ground. In contrast, oil-based droplets are much smaller and can remain suspended in the air for a longer time. Water-based pesticides evaporate quickly at atmospheric temperatures and lose their effect, whereas oily pesticides are more resistant to evaporation and can reach farther distances.

Spraying 1 decare of area takes only 1 minute. This results in significant savings in time and labor costs. Compared to garden sprayers, in terms of time, spraying can be done 60 times faster and more easily.

It also offers great advantages in pesticide consumption and cost: At least 50%, and on average 90% savings are possible. Since the pesticide is applied in fog form, it does not drip onto the plant or soil, providing maximum effectiveness. The fog contacts every area, even under the leaves, effectively neutralizing pests at once.

Compatible with Various Pesticide Formulations EC, SC, and POWDER formulations can be applied. EC (Emulsion Concentrate) pesticides can mix directly with oil, while other formulations require a combination of oil, water, and pesticide. You can obtain “LP fogging oil,” which mixes with water, from our company. There are EC formulation (fluid) pesticides available in the market that effectively neutralize the pests you need.

When you prefer a pesticide, you should prioritize EC formulations; if no suitable solution is found, then other formulations (SC or powder) are recommended. With thermal foggers, you can complete the entire season with 3-4 pesticide application: eliminate insects, viruses, fungi succesfully.

Much More Effective than Traditional Methods Thermal fogging machines heat pesticides and spray them as smoke with particle sizes around 10 microns. This method increases the pesticide’s effectiveness 12 times more, rather than decreasing it. Contact-effective pesticides spread homogeneously over wide areas and easily contact pests. For example, with a 5-liter mixture, thermal fogging machines produce approximately 2.39 trillion particles, while traditional sprayers produce only 190 billion particles with the same amount.

These machines ensure pesticides spread evenly and in a thin layer over plant surfaces. Thus, the pesticide remains airborne longer and contacts pests more effectively. At the same time, thermal fogger method causes less environmental harm and leaves no residue on plants. When pesticide is applied in fog form, there is no residue risk even with pesticides that have not yet reached the harvest waiting period. For example, a pesticide labeled with a 90-day harvest period can be applied in fog form with thermal fogger and export can be done residue-free in just 4 days. Thanks to this advantage, spraying can be safely done even if the harvest time is near, preventing product loss.

Reduces the Need for Systemic Pesticides Thermal fogging machines efficiently apply contact-effect insecticides and fungicides, eliminating the need for systemic pesticides. Systemic pesticides act through the pest’s ingestion and leave residues, resulting in high pesticide consumption. In contrast, spraying with thermal fogging relies on widespread use of contact-effect pesticides, providing a more cost-effective, environmentally friendly, and effective solution. This ensures effective pest population control and significant savings in the spraying budget.

Why is the machine's impact capacity is larger in Pest control, and less in Frost control?

It is important to note that in pest control, there is no race against time, unlike in frost protection.
While in frost protection the machine must be parceled to 20ha maximum (because if it is parceled to a bigger land, the artificial fog created in a short time wouldnt be dense enough, and wouldn’t have enough reflectivity and protectivity). On the contrary, in pest control activity, the smoke doesn’t need to be dense, and you have no time constraint to treat a larger land.

How is liquid fertilization application done?

Nowadays, the costs of pesticides and fertilizers are increasing day by day. Therefore, maximizing savings is extremely important for agricultural producers. In liquid fertilizer applications made with traditional garden sprayers, approximately 90% of the fertilizer is wasted; only about 10% makes contact with the leaf. Moreover, this contact usually occurs only on the underside of the leaf, while the upper surfaces mostly do not receive any fertilizer. A large portion of the fertilizer falls onto the plant stem or directly onto the soil, failing to achieve the intended effect.

However, by applying fertilizers in fog form to the foliage, the entire upper and lower surfaces of the leaf are covered. There isn’t a single spot left untreated. Thus, the fertilizer reaches both sides of the leaf in the most economical way. Additionally, the fertilizer applied with this method is easily absorbed through the stomata under the leaf and incorporated into the plant’s system. This increases efficiency and results in significant savings on fertilizer costs.

Fertilizer applications may need to be done at somewhat more frequent intervals compared to sprayers until the desired yield is achieved.
