1. Scope <br> This standard specifies the types of pesticides, hygienic standards and guidelines for use of AA grade green foods and A-grade green foods.
Musk Xylol has been used since the early 1900s as a fragrance ingredient. Natural musks are obtained from plants and animals, and are much sought after for use as fixatives in perfumes. Synthetic musks are, however, of greater industrial importance. They are found in many perfumes, soaps, detergents, and cosmetics.

NY/T1999 Green Food Origin Environmental Quality Standard
3. Definitions <br> This standard uses the following definitions.
3.1 Green food 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 special agencies.
3.2AA grade green food means that the environmental quality at the place of production conforms to the “Environmental Quality Standard for Green Food Originâ€, and chemical synthetic fertilizers, pesticides, veterinary drugs, feed additives, food additives and other harmful to the environment and health are not used in the production process. The substances are produced according to the organic production method. The quality of the products conforms to the standards of green food products, and the products approved by the specialized agencies are permitted to use the AA grade green food mark.
3.3A grade green food means that the environmental quality of the place of production conforms to the “Environmental Quality Standard for Green Food Producing Areaâ€. The production process is strictly in accordance with the requirements for the use of green food production materials and the requirements of production operation regulations, and the limited use of chemical synthetic production materials is limited. The green food product standard, which is approved by a specialized agency, is licensed to use the A-grade green food mark.
3.4 Bio-sourced pesticides refer to the direct use of bioactive substances produced by biological organisms or biological metabolic processes or substances extracted from organisms as pesticides for controlling pests and diseases.
3.5 Mineral Sources The active ingredients of pesticides originate from mineral inorganic compounds and petroleum pesticides.
3.6 Development of synthetic organic pesticides artificially synthesized by a commercial pesticide organic chemical industrial production, and low toxicity comprising mesogenic acaricides insecticide, fungicides, herbicides, can be produced in the green stage A Limited use.
3.7AA grade green food production data refers to production materials that have been identified by specialized agencies and meet the requirements of green food production, and are officially recommended for the production of AA grade and A grade green food.
The 3.8A grade green food production data refers to the production materials that have been approved by the specialized agencies and meet the requirements of Class A green food production and are officially recommended for the production of Grade A green food.

5. Guidelines for use <br> Green food production should start from the whole ecosystem of crops, pests and diseases, and comprehensively apply various control measures to create environmental conditions that are not conducive to the breeding of pests and diseases and beneficial to the proliferation of various natural enemies, and maintain the agro-ecosystem. Balance and biodiversity to 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.
