Many people express concern about the use of small amounts of pesticides in the production of green foods, but they are actually unnecessary. There are many kinds of pesticides, high in drugs and low in drugs. Many of the newly developed pesticides in the world are low-toxic, low-residue, biodegradable environmentally-friendly pesticides, and some are even the normal components of organisms, so-called biological pesticides , which are not The environment causes harm. Since green food can meet the national standards, it proves that it is a non-polluting, non-hazardous, and safe food for people, and people can eat it with confidence.
In order to ensure the quality of green food, rational use and management of pesticides for the production of green foods, China has specially formulated the "Rules for the Use of Green Foods". It is one of the series of guidelines for the production of green food.
The rules stipulate that green food production should start from the whole ecosystem of crops, such as pests and diseases, and comprehensively use various control measures to create environmental conditions that are not conducive to the growth of pests and diseases and beneficial to the proliferation of various natural enemies, and maintain the balance of agro-ecosystems. Biodiversity reduces the damage caused by various pests and diseases. It is necessary to give priority to the use of agricultural measures, through the selection of pest-resistant varieties, try to use light, color to trap pests, mechanically capture pests, mechanical and manual weeding and other measures to control pests and diseases.
In special cases where pesticides must be used, the following guidelines should be followed by the classification of green foods:
AA grade green food pesticides are allowed to use AA grade green food production materials pesticide products. In the case of AA grade green pesticides production can not meet the needs of the plant protection work, and allow the use of certain pesticides specified method.
AA grade green food pesticides allow the use of AA grade and A green foods to produce pesticide products. The specified pesticides and methods are allowed in the case where the AA grade and A grade green food production information pesticide products cannot meet the needs of plant protection work.
In addition, the following regulations must be strictly enforced:
1. It is strictly forbidden to use pesticides that are highly toxic, highly toxic, highly residual or have three toxicity (carcinogenic, teratogenic, mutagenic).
2. Each organic synthetic pesticide (organic synthetic product containing pesticides of Grade A green food production materials) is only allowed to be used once during the growth period of a crop.
3. The final residue of organic synthetic pesticides in agricultural products shall meet the maximum residue limit (MRL) requirements of GB4285 and other standards.
4. It is strictly forbidden to use high-toxicity and high-residue pesticides to control pests and diseases during storage.
5. It is strictly forbidden to use genetic engineering varieties (products) and preparations.
In addition, the agricultural department based on the comprehensive analysis of pesticide testing results in the vegetable market, found that the pesticide residue is easy to exceed the standard vegetables: cabbage, green vegetables, chicken, amaranth, cucumber, cabbage, kidney beans, mustard and so on. Among them, amaranth and rapeseed are the most likely to be contaminated. The green worm has strong resistance, and the vegetable farmers will choose high-toxic pesticides in order to kill the insects as soon as possible. The pests of amaranth often grow in the mother, so the farmers use a lot of highly toxic pesticides to irrigate the roots, and the internal drug use characteristics of the leek make the poisons spread throughout the whole body. According to the China Pesticide Network , solanaceous vegetables such as green peppers, tomatoes, etc., tender vegetables such as beans, and bulbous vegetables such as onions, garlic, onions and other pesticide residues are less than the standard phenomenon.
