1, choose low toxicity pesticides. With the continuous development of the chemical industry, there are more and more kinds of pesticides, and there is a wide range of pharmaceutical agents that can be used to control a certain pest and disease. For the safety of humans and animals, under the premise that pests and diseases can be prevented, low-toxic and low-residue pesticides should be selected. 2, the drug concentration should be low. When the selected pesticide species is determined, the lower limit of the range of efficacy should be selected when formulating the pesticide. Because the application of low-concentration liquid medicine is not only for the safety of humans and animals, the cost can be reduced, but also the resistance of individuals with residual pests can be prevented, thereby prolonging the life span of the pesticide. 3, alternating use of various agents. Due to the wide variety of pests and diseases in vegetable fields, rapid development and frequent application of pesticides. If the same agent is administered continuously, the control subjects will develop resistance to the agent and the efficacy will be reduced. For this reason, some different kinds of medicaments with the same efficacy should be used interchangeably to avoid the occurrence of resistance. 4, medication should pay attention to time. The timeliness of the so-called medication has two meanings: First, in the event of pests and diseases, to seize the opportunity to use drugs in time, the sooner the better, so as not to miss the time to produce the best efficacy; Second, according to the growth period of the vegetables To adjust the concentration and quantity of pesticides, because the requirements for the concentration and quantity of the liquid are different at different times.
