What are the factors that affect the effect of drone plant protection?

(1) Factors of pesticides themselves

The composition, physicochemical properties, dosage form, mode of action, and production quality of pesticides all affect the efficacy of the drug. Different companies have different production processes and production capacity of preparations, and the efficacy of the drug will also vary. At the same time, it cannot be ruled out that some companies do Article, stealing content affects efficacy. In addition, agrochemicals spray drone for plant protection can also be added with anti-flying additives. High-quality anti-flying additives have the characteristics of enhancing adhesion, permeability and spreading, anti-drift, anti-evaporation, etc., thereby improving the spraying effect. Of course, in addition to the drug itself, the method of dispensing is also very important.

(2) Influence of spray quality

The quality of the spray directly affects the efficacy of the medicine. At present, the spray droplets sprayed by conventional spray equipment are too large, and the droplets will bounce when sprayed on the surface of crops, and about 50% of the liquid medicine will fall on the ground, resulting in a decrease in the efficacy of the medicine. If the diameter of the droplets of the same amount is reduced by half, the number of droplets obtained can be increased by 8 times, and the medicinal effect is also greatly improved.

(3) The concept of prevention and treatment needs to be changed

It is necessary to change the existing prevention and control concepts such as "applying drugs to see the disease, focusing on treatment and ignoring prevention", adhere to the principle of "prevention first, comprehensive prevention and control", scientifically select pesticide varieties, and recommend rotating the use of different ingredients and mixing with protective preparations. Delay the onset of resistance. On the other hand, it is necessary to enhance the sense of responsibility and enrich the professional knowledge of plant protection to better cope with the complex pest and disease situation in the field.

(4) Temperature and humidity affect the efficacy of the drug

Temperature: Under high temperature, the active ingredients of pesticides are easily photolyzed or decomposed, the liquid medicines are easily volatilized or evaporated rapidly, and the stomata of crops may be closed, which is not conducive to the absorption of pesticides by crops. If the temperature is too high or too low, the efficacy of the drug will be affected. Generally speaking, the effect of the drug is better when the temperature is in the range of 20 to 30 °C. If the temperature is higher than 35 °C, it may have a greater impact on the safety and effect of the operation (of course, the specific drug Temperature requirements may vary).

Humidity: The plant protection high efficacy agricultural drone operation itself consumes less water, so the impact of humidity will be relatively greater. In a dry environment, the water consumption needs to be increased accordingly, otherwise the water consumption can be appropriately reduced.

Wind: Studies have found that a certain wind speed is more conducive to improving the deposition efficiency of droplets. It is recommended to apply the spray at a wind speed of 1-4m/s, which is conducive to the deposition of droplets on the target. Of course, it is recommended to work in winds below level 3.

Light: Different types of pesticides may have different sensitivity to light. For example, phoxim, pyrethrin, etc. are easy to be photolyzed, and are best used for soil treatment, storage pest control and night spraying for pest control; and photosynthesis inhibitor herbicides (such as substituted urea, mesitrazine, etc.) Better lighting conditions are required. At the same time, pay attention to other weather conditions before and after spraying, such as whether it will rain, whether there is smog, etc.

(4) Crops and pests

The type, growth stage, height and density of crops, as well as the types, living habits and severity of pests and diseases all have an impact on the control effect. This requires adjustment of the amount per mu, operating parameters and drug use according to the specific situation, and also requires more professional plant protection knowledge.
