At present, various regions have begun to enter the plant protection operation season, and the agricultural spraying uav flight defense team has also been busy. In the process of agricultural spraying uav flight prevention operations, in order to reduce the number of drugs used, at the same time to achieve the purpose of improving the control effect , Often encounter two or more pesticides, foliar fertilizer mixed use. Although there are many advantages to mixing pesticides, avoid mixing them randomly. Unreasonable mixing is not only useless, but also has the opposite effect. Pay attention to the following points when mixing pesticides.

1. The mixing order of agricultural spraying uav pesticides should be accurate. The mixing sequence of foliar fertilizers and pesticides is usually: micro fertilizer, water soluble fertilizer, wettable powder, water dispersible granules, suspension agent, microemulsion, water emulsion , Liquid agent, emulsifiable concentrate, add one after the other, each one is mixed well, then add the next one. In principle, do not mix more than three kinds of pesticides. Try to reduce the use of wettable powders to avoid clogging the nozzles of agricultural spraying drones.
2. For agricultural spraying uav, add water first and then add medicines. For the second dilution and mixing, it is recommended to add some water to the dispensing tank first, and then mix the first pesticide. Then, dilute the remaining pesticides in other containers separately, pour them into the dispensing barrel after mixing, mix well, and so on (If you want a good effect, don’t be lazy).
3. No matter what chemicals are mixed with agricultural spraying uav, you should pay attention to "Now use it, do not put it for a long time." Although the drug solution did not react when it was first dispensed, it does not mean that it can be left for a long time at will, otherwise it will easily produce a slow reaction and gradually reduce the efficacy of the drug.

Agricultural spraying uav should be equipped with medicine in advance for flight prevention operations, which is conducive to improving the efficiency of drone operations. When several diseases and insect pests occur at the same time, this method can reduce the number of agricultural spraying drones and reduce working hours, thereby improving efficacy.
