The application of pesticides is one of the most regular crop management in the field. How to apply pesticides reasonably and produce the none-residue crop products is the most important goal in the modern safe agriculture. Principles of rationalized application of pesticides are identifying the pests, realizing the damage patterns, outburst seasons and condition of pests, applying the registered pesticides in suitable time with recommended concentration, application time and frequency according to the label outside the pesticide product, harvesting the crop product after the preharvest interval. Therefore, no health-damaged residues on the crop product will be released in the market if crop producer applied the pesticides according to the instructions on the pesticide label mentioned above. But the government always found the none-registered pesticides or excessive residues of pesticides on the crop products in the market. The reason is simply that the pesticide manufactories registered their pesticide products on the major crops or economic crops based on the profits. They have no interest to register the market of minor use, i.e. the minor pests on the major crops and the major pests on the minor crops. In this situation, the crop producers were forced to use the unregistered pesticides to ensure the yield and quality of crop products, and caused the illegal application of pesticides in the field. To solve the minor use problem as a whole, the government has drawn up the protocol “Pesticides Application System Based on the Crop Grouping”. In this protocol, pesticides could be registered according the “representative crops” and “representative pests”, and extended their application range to solve the problem of minor use. In this system, pesticide manufactories could reduce the registration fare and be willing to register the extended crops of minor use. Also, the government does their responsibility to
manage the pesticides in the market and field, reducing the sorts and amounts of
pesticides applied in the field, and the crop producers get the low-priced and
extended pesticides which could be applied in the field without against the law.
If the protocol was passed, the government, manufactory and crop manager are
all-win under the new pesticide registration system.
