1 Scope This standard specifies the types of pesticides , hygiene standards and guidelines for use in the production of AA grade green foods and Grade A green foods. This standard applies to bioogenic pesticides (biogenicpesticides), mineral-derived pesticides (pesticidesoffossilorigin) and synthetic organic pesticides (syntheticorganicpesticides). The provisions contained in the following standards constitute provisions of this standard by reference in this standard. The versions shown are valid at the time of publication. All standards will be revised and parties using this standard should explore the possibility of using the latest version of the following standards. GB4285-84 pesticide safety standard 3. Definition This standard uses the following definition. 3.1 Green food It refers to non-polluting safe, high-quality, nutritious foods that are produced according to the principle of sustainable development and produced according to specific production methods and approved by specialized agencies. 3.2AA grade green food It means that the environmental quality at the place of production conforms to the “Environmental Quality Standard for Green Food Producing Areasâ€. In the production process, chemically synthesized fertilizers, pesticides, veterinary drugs, feed additives, food additives and other substances harmful to the environment and health are not used. Production mode production, product quality in line with green food product standards, approved by specialized agencies, licensed to use AA grade green food logo products. 3.3A grade green food Refers to the environmental quality of the production site in line with the "Environmental Quality Standard for Green Food Origin".

Reduce the damage caused by various pests and diseases. Priority is given to the use of agricultural measures, through the selection of disease-resistant and insect-resistant varieties, non-chemical pesticide seed treatment, cultivation of strong seedlings, strengthening cultivation management, cultivating and weeding, deep-turning the soil in autumn, cleaning the pastoral, rotating cropping, intercropping and other measures to prevent The role of pests and diseases. Should also try to use light, color to trap pests, mechanical capture of pests, mechanical and manual weeding and other measures to control pests and diseases.
