In general, solid pesticides and fertilizers are directly mixed, and the requirements are not very strict, and liquid pesticides and methamidophos, as well as thiophanate, Jinggangmycin, Yeqisan, Kuweiwei, etc., cannot be mixed with ammonium bicarbonate, ammonia water, and ash. Mix limestone and the like. Alkaline-strong pesticides, such as stone sulphur mixture, Bordeaux mixture and rosin mixture, cannot be mixed with chemical fertilizers such as calcium phosphate, ammonium sulfate, ammonium nitrate or ammonium chloride. The arsenic-containing pesticide cannot be mixed with sodium salt or potassium salt fertilizer. .
In the pear tree, more fruit and emulsifiable pesticides will increase the insect pests. In the case of vegetables, cockroach and similar drugs and daisen zinc or daisen ring are mixed, which is also prone to phytotoxicity. If emulsifiable emulsifiable agents are used, there is a tendency to aggravate phytotoxicity, deltamethrin and organophosphorus pesticides. Mixed use will increase the phytotoxicity of pesticides. Benzimidazole pesticides cannot be mixed with copper-containing pesticides, otherwise they will cause phytotoxicity to agricultural products. Bordeaux mixture is mixed with stone sulfur mixture, which is easy to cause phytotoxicity to plants. Organophosphorus pesticides are mixed with rosin mixture, which is easy to cause phytotoxicity to crops.
