Summer is the most common season for various crops, pests and weeds, and it is also the period with the highest number of pesticides, the largest amount of pesticides used, and the most problematic. In order to achieve safe, economical and effective purposes, the following issues should be noted.
1. Purchase "Reassuring Medicine". When purchasing pesticides, do “four no purchasesâ€: first, no pesticide labels or labels are not incomplete, and second, the label “three certificates†(pesticide registration certificate, product standard number, production license) is not complete. Buy; Third, the appearance quality is not qualified, do not buy; Fourth, the drug that exceeds the product quality guarantee period does not buy. 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. Rational use of pesticides. Pesticide use to pay attention to six: 1 symptomatic medicine. There are many varieties of pesticides and different characteristics. The most suitable pesticides should be selected for the control objects. 2 timely medication. 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 herbicide should be used before the crop is germinated. 3 Strictly control the amount of application. Any pesticide should be used according to the recommended dosage. Any increase or decrease may cause crop damage or affect the control effect. 4 Application should be even and thoughtful, can not be re-sprayed or leaked to ensure the safety of crops, effective against pests and diseases. 5 Reasonably mix pesticides. After mixing, the toxicity to humans and animals should not be increased, chemical changes should not occur between the active ingredients, and the cost of medication should not be increased. 6 to apply safely. 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.
3. Problems occur in a timely manner. 1 When the drug effect is very poor or the phytotoxicity occurs, the drug should be sent to the pesticide testing unit for inspection. 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.
