Spring is the germination period of various pests of crops. The base number of pests is small during this period and it is relatively easy to control. Therefore, prevention and control of various pests and diseases in spring is very important and the accurate use of pesticides is very important. How can we use pesticides correctly? One must prescribe the right medicine. Before purchasing pesticides, it is necessary to clarify the targets for prevention and treatment, determine what pesticides to buy, and not follow the trend. Second, avoid buying fake drugs. When purchasing pesticides, it is necessary to “look at one and pay attention,†that is, to see if the pesticide registration certificate, production license, pesticide standard number, and product certification certificate are complete; secondly, whether pesticide packaging is intact or not; and whether the powder is agglomerated or not. Whether the emulsion is layered or not, and whether the liquid agent precipitates. Also pay attention to the effective period of pesticides. Third, we must use reasonable mix. However, in the following cases, the use of pesticides is forbidden: If pesticides that are alkaline substances are easily decomposed and the efficacy of pesticides is reduced or even become ineffective, they cannot be mixed with alkaline pesticides. For example, phoxim, pyrethroids, etc., cannot be mixed with alkaline agents such as lime sulfur and Bordeaux mixture; pesticides that damage the emulsion after mixing cannot be mixed. For example, organic sulfur and organic phosphorus pesticides cannot be mixed with pesticides containing copper preparations. In addition, we must pay attention to pesticide safety interval. The time between the last spraying and harvesting must be greater than the safety interval to prevent human and animal poisoning.
