1. When purchasing "safe medicine" to buy pesticides, do "four do not buy", first, no pesticide label or label is not complete, do not buy; second, the label "three certificates" (pesticide registration certificate, product standard number, production license) The medicines with incomplete labeling are not bought; the third is that the appearance quality is not qualified, and the fourth is that the medicines that exceed the product quality guarantee period are not bought. Then, according to the pesticide packaging, the types of pesticides are recognized: green as herbicide , red as insecticide , black as fungicide, blue as rodenticide, and yellow as plant growth regulator.
2. Reasonable use of pesticides and pesticides to achieve six notes: First, the right medicine. There are many varieties of pesticides and different characteristics. The most suitable pesticides should be selected for the control objects; the second is the timely use of drugs. The time for medication is correct, and the control effect is ideal. If the protective fungicide must be used before or during the onset of the disease, the pre-emergence herbicide should be used before the crop is germinated; the third is to strictly control the amount of application. Any pesticide should be used according to the recommended dosage. It is easy to increase or decrease the crop phytotoxicity or affect the control effect. Fourth, the application should be even and thoughtful, and it can not be re-sprayed or leaked to ensure the safety of crops and is effective for pests and diseases; Rational mixing of pesticides, after mixing, can not increase the toxicity to humans and animals, chemical changes between the active ingredients can not occur, can not increase the cost of medication; sixth is to safely apply drugs. Dispensing and applying drugs should prevent pesticides from contaminating the skin. It is forbidden to spray high-toxic pesticides during high temperature in the summer, and the application time should not be too long. At the operation site, it is necessary to keep the liquid medicine, poisonous valleys, poisonous species, etc., to prevent poisoning of humans and animals. It should also be noted that highly toxic and highly toxic pesticides are prohibited from being used on crops such as melons, vegetables, and fruit trees to be responsible for consumer safety. In addition, pesticides must be noted for the safety of crops and the environment.

If it is unqualified or counterfeit, it can go to the industry and commerce, consumer association, technical supervision and other departments to complain or go to court.
2 remedy for timely remedy, first, fertilization and remedy, the phytotoxicity of the leaves on the surface of the drug spots, leaf edge coke or plant yellowing, fertilizer can be applied to reduce the degree of phytotoxicity; second, to inhibit or interfere with plant growth Herbicide phytotoxicity can be sprayed with gibberellin to relieve; third is the phytotoxicity of some rice field herbicides, proper drainage can reduce the phytotoxicity.
3 In the event of a pesticide poisoning accident, it is necessary to take first aid measures or send it to the hospital for rescue.
