Generally, the mixing sequence of foliar fertilizer and pesticide is to add foliar fertilizer, wettable powder, suspending agent, aqueous solution and emulsifiable concentrate in turn, and each pesticide should be stirred evenly first. Attention should be paid to adding water first, then adding medicine, diluting it for the second time, and spraying it immediately after preparing the medicine, so as not to reduce the efficacy. Mixed pesticides cannot produce adverse chemical reactions, such as hydrolysis and acidolysis. After mixing different kinds of pesticides, it will not harm crops.

A, pesticide dispensing sequence table

1. No matter what pesticides are used, they should be diluted twice, and the mixing order of pesticides should be accurate. The mixing order of foliar fertilizer and pesticide is generally foliar fertilizer, wettable powder, suspending agent, aqueous solution and emulsifiable concentrate, and each pesticide should be stirred evenly first. Also pay attention to adding water before adding the medicine, diluting it for the second time, and spraying it immediately after preparing the medicine, so as not to reduce the efficacy.

2. It should be noted that mixed pesticides cannot produce adverse chemical reactions, such as hydrolysis and acidolysis. And can ensure the normal efficacy or increase the efficacy without affecting the physical properties of the efficacy. Some foliar fertilizers and pesticides have no adverse reactions when they are first mixed, but they are easy to be slow to respond after being left for a long time, which will lose their efficacy and even cause phytotoxicity.

3. After mixing different pesticide varieties, it will not cause harm to crops. For example, the mixture of organophosphorus pesticides and diphacinone will cause phytotoxicity to rice, and the mixture of Bordeaux mixture and sulfur will easily cause phytotoxicity to crops.

4. The mixture of pesticides should be reasonable, and the collocation between species should be reasonable; Pesticides should be mixed to avoid increasing their toxicity; Attention should also be paid to the antagonism between pesticide varieties to ensure the effect of pesticide mixing.

2. It has a business place of not less than 30 square meters and a storage place of not less than 50 square meters, and is effectively isolated from other commodities, living quarters and drinking water sources.

3, run other agricultural inputs, should have a relatively independent pesticide business area.

4, there are traceable electronic information code scanning identification equipment and computer management system to record the electronic accounts of pesticide purchase, storage and sales.

5, with the management of pesticides to adapt to the technical personnel. Having rules and regulations suitable for the pesticides it deals in.
