What should be paid attention to when mixing pesticides?

Fighting drugs is one of the important measures that are indispensable for the prevention and control of vegetable diseases and insect pests. Due to the variety of vegetable diseases and insect pests, it is often necessary to control several pests and diseases at the same time, and even treat both diseases and insects. In order to save the medicinal workers, often a multi-drug is used, and several pesticides are mixed. When mixing pesticides, you should understand the nature of each pesticide and the possibility of mixing between pesticides. Otherwise, it may easily reduce the efficacy or even cause phytotoxicity. For example, alkaline pesticides such as Bordeaux mixture and lime sulfur mixture cannot be mixed with Daisen zinc and dimethoate. However, with the increase and wide application of new pesticide varieties, the above-mentioned pesticides such as Bordeaux liquid and stone sulphur mixture have gradually disappeared due to the trouble of preparation. Therefore, common pesticides on vegetables, such as trichlorfon, dichlorvos, dimethoate, fruit, broccoli, fennel, zinc, thiophanate, thiram, carbendazim, chlorothalonil, Resveratrol, Ethylphosphorus, Captan, etc. can be mixed according to the needs of pest control.

When mixing pesticides, attention should be paid to the calculation of concentration. Some people mix 1000 times of the drug with 1000 times of the drug, and then mix it. It is used as 1000 times of A and B. In fact, after mixing A and B The multiple of the pesticide is 2000 times, and 1 part of the medicine and 1 part of the medicine should be included in the amount of water required to be 1000 times.
