Now, with the extensive use of chemical pesticides, causing most of the pesticide residues in fruits and vegetables. This issue has aroused concern, the voice of the people's pollution-free vegetables is getting higher and higher. In order to solve the problem of excessive pesticide residues from the source, at the same time of using non-chemical to control pests, how scientific and rational choose chemical pesticides and make the pesticide residues  below the level of allowing to develop green agriculture has become an inevitable trend.

Pollution-free vegetables for pesticide requirements in addition to efficient, quick, the most important thing is to be safe, low toxicity and residue. Its agents can be rapidly digested in nature (such as hydrolysis, photolysis or microbial decomposition). Do not pollute the environment, but also reduce the injuries for  predators, pollinators and so on, and it has few injury for vegetables. There are some pesticides that are suitable for organic vegetable production.

1. Biological pesticides. Biological pesticides have special effect on controlling the pests, and it is a highly secure pesticides. It has the  characteristics of high efficiency, low toxicity, no residue, slow resistance and so on.Such as bacterial insecticide BT (Bacillus thuringiensis microbial pesticides), avermectin, participation alkali plant pesticides, fungal pesticides (Beauveria bassiana); insect virus pesticides and insect pheromones (such as sexual attractants).

2.The modern concept of botanical pesticides. Just the plant extracts which have specific effect on pests feeding, repellent, hinder development and reproductive interference. (such as azadirachtin, TSN).

3.Insect growth regulators. It can play a control action through prevent pests desquamate, interfere with its development. Harmless to people and the higher animals, the impact on the natural enemies is small, it is safe for environment. Such as chlorfluazuron, diflubenzuron, buprofezin, have been widely used, new varieties such as cyromazine, rice has also begun to promote.

4.The new antibiotic agents. Such as spinosad has  efficient feeect to confrontational vegetable pests, but it is very safe to humans and higher animals, the safety interval is short and it is very suitable for the using in the vegetable.

5.Efficient strong selective agents. Such as carbamate pirimicarb only showed efficient  to aphids(with contact and stomach poison, fumigation triple role), and it has no harm to other organisms, and the residual effect period is short,it is also safe to crops and natural enemy. It is the ideal Pharmacy to product pollution-free vegetables and maintain the ecological balance of vegetable plantation.
