The reasonable mixing of pesticides can improve the control effect, delay the development of drug resistance of pests and diseases, reduce the amount of drugs used, and prevent the use of pesticides for different pests and diseases, thereby reducing the number of applications and thus reducing labor costs.
In the process of plant protection drone flight defense operation, in order to reduce the number of medications and achieve the purpose of improving the control effect, it is often encountered that two or more pesticides and foliar fertilizers are used in combination. The following Tianying Brothers Xiaobian introduces the matters needing attention when mixing pesticides in flying defense operations.
1, the mixing order
The order of foliar fertilizer and pesticides is usually: micro-fertilizer, water-soluble fertilizer, wettable powder, water-dispersible granules, suspending agent, microemulsion, water emulsion, water, emulsifiable oil are added in sequence, and each is stirred thoroughly after adding one kind. Mix and then add the next one. In principle, do not mix more than three kinds of pesticides, and try to reduce the use of wettable powders to avoid blockage of the plant protection drone nozzle.
2, secondary dilution
It is recommended to use the second dilution method when mixing pesticides. First add some water to the dispensing barrel and add the first pesticide. Then mix and release the remaining pesticides in the container and pour them into the dispensing barrel and mix them. Stir well and mix well.
3, the current distribution
The mixed pesticide should be used now. Although the liquid does not react when it is just mixed, it does not mean that it can be placed for a long time. Otherwise, it will easily produce a slow reaction and gradually reduce the effect. The use of the Tianying Brothers plant protection drone for flying defense operations should be accompanied by good medicine in advance, which is conducive to improving the efficiency of plant protection drones.
