However, improper use can also cause harm. The state has strict management systems and regulations from production to circulation, especially paying attention to the problem of excessive pesticide residues. To maintain green crops, pesticides must be carefully identified and used correctly.

Identification and identification of pesticides:
1. Check that the inner packaging of the pesticide preparation must be firmly affixed to the inner packaging, or printed directly, marked on a small package. The pesticide label has legal effect. If the user applies the medicine according to the method of use on the pesticide label, there is no medicine effect, and even the phytotoxicity occurs, the pesticide manufacturer should bear full responsibility.
The contents of the label include: product name, specification, dosage form, active ingredient, pesticide registration certificate number, product standard code, production certificate number, net weight or net volume, scope of application, use method, application contraindication, poisoning symptoms and first aid, phytotoxicity, safety Interval, storage requirements, etc. Toxicity signs and pesticide class marks, as well as date of manufacture and lot number, should also be indicated.
The shelf life of pesticides is generally two years. The imported pesticide label should be marked with the Chinese pesticide registration number and the Chinese product name registered in China. The label should be consistent with the domestic pesticide labeling requirements except for the standard code and the production certificate number.
2. Inspect the outer packaging according to the national standard GB3796-1986 "General Principles of Pesticide Packaging". The outer packaging box of the pesticide with the moisture-proof layer of the corrugated cardboard outer packaging container shall have the label on the label indicating the product name, category, specification, gross weight, production date, Batch number, storage and transportation indicators, signs, toxicity signs, production plant names. At the bottom there should also be a color strip parallel to the bottom edge, indicating the type of pesticide.
Color marking strip of pesticide category: herbicide---green; insecticide ---red; fungicide---black; rodenticide---blue; plant growth regulator---dark yellow;
There must be a certificate of conformity and instructions in the outer packaging container of the pesticide. Liquid pesticide preparations should generally not exceed 15 kg per case, and solid pesticide preparations should not exceed 25 kg per bag.
The pesticide network reminds farmers to pay attention to the authenticity and toxicity of pesticides when purchasing, and scientifically purchase according to the above inspection standards, and ensure the safety of medication.
