Purchasing quality pesticides is not only about ensuring the product meets standard specifications, but also about verifying that the label and instructions are clearly presented. When registering pesticides, strict guidelines are in place regarding labeling. The label must include essential details such as the pesticide name, active ingredient and concentration, formulation type, pesticide registration number or temporary registration number, production license or approval document number, product standard number, company name and contact information, manufacturing date, batch number, expiration date, net weight, product performance, usage methods, application techniques, toxicity level, precautions, first-aid measures for poisoning, storage and transportation instructions, pictograms, and other relevant information. Additionally, the packaging unit should be indicated. If any of these elements are missing, it’s wise to exercise caution when purchasing.
Here are some key points to consider:
1. **Check the Pesticide Name**: Whether domestic or imported, the product must have a common Chinese name, along with the active ingredient and its form. This helps ensure clarity and correct identification.
2. **Verify the “Three Certificatesâ€**: These include the pesticide registration number, production license number or approval certificate number, and the product standard number. Domestic products typically require a Pesticide Registration Number, a Quasi-Production Certificate, and a Quality Standard Certificate from the Ministry of Agriculture. Imported products may only have a registration certificate, while domestically packaged imports need separate numbers for registration, approval, and standards.
3. **Understand the Registration Types**: Pesticide registration certificates come in two forms: official (PD) and temporary (LS). For agricultural use, temporary registrations are marked with "LS" (e.g., LS20071573), while official ones use "PD" (e.g., PD20080005). For public health products, temporary registrations use "WL" and official ones use "WP." Always check the certificate to confirm authenticity before purchasing.
4. **Review the Scope of Use**: Select a pesticide that matches the crop, pest, or weed you're targeting. When multiple options are available, prioritize those with lower toxicity, minimal residue, and better safety profiles. Avoid using highly toxic pesticides on vegetables, fruit trees, or medicinal plants.
5. **Check Net Content, Date, Batch, and Expiry**: The label should clearly show the net content in legal units—grams, kilograms, milliliters, or liters. The production date must follow the format year-month-day, with four digits for the year and two for the month and day. Ensure the product is within its validity period, which can be expressed as a warranty period, effective date, or expiry date. Never purchase expired or unmarked products.
6. **Note the Color Coding**: Most pesticide labels feature a color-coded band indicating the type of pesticide. Fungicides are black, insecticides are red, herbicides are green, rodenticides are blue, and plant growth regulators are dark yellow. If a product contains multiple active ingredients, the color band will reflect all of them.
7. **Look for Toxicity Symbols**: The label should prominently display the toxicity level and corresponding symbol. In China, pesticides are classified into five levels: extremely toxic, highly toxic, moderately toxic, low toxicity, and slightly toxic. Each level has a specific symbol, and the toxicity level is usually marked in red for visibility.
By paying attention to these details, consumers can make safer and more informed choices when purchasing pesticides. Always read the label carefully and consult reliable sources if unsure.
