What are the precautions for pesticide application? Pesticide is an important part of agricultural production. Although it advocates pollution-free planting, for most agricultural crops, it is impossible to leave pesticides. Sometimes we have to mix and use several pesticides during the use of pesticides. What are the precautions for common pesticides? How can we mix pesticides to make pesticides have better results? Here are some suggestions.
In general, solid pesticides and fertilizers are directly mixed, and the requirements are not strict, and thiophanate, Jinggangmycin, and quetiapine cannot be mixed with ammonium bicarbonate, ammonia water, grass ash, lime nitrogen, and the like. Alkaline-strong pesticides, such as stone sulfur mixture, Bordeaux mixture and rosin mixture, cannot be mixed with chemical fertilizers such as calcium phosphate, sulfuric acid, ammonium nitrate and ammonium chloride. The arsenic-containing pesticide cannot be mixed with sodium or potassium fertilizers.
The pesticide mixture should be established on the basis of not damaging the original physical and chemical properties after mixing, and the control effects are not interfered with each other or improved. When mixing pesticides, be careful not to mix biological pesticides with chemical fungicides. Organophosphorus, pyrethroid insecticides, and dithiocarbamate fungicides cannot be mixed with alkaline pesticides. It is the same type of pesticide to avoid mixing, so as not to damage the nature of pesticides.
