When many farmers use **pesticides** to manage pests and diseases, they often overlook the required waiting period before harvesting vegetables, leading to excessive pesticide residues on the produce. To help farmers understand and follow proper guidelines, the following are the safety intervals for various pesticides as outlined by the Ministry of Agriculture's Vegetable Pesticide Testing Institute.
**Fungicides**:
Chlorothalonil WP can be applied up to 7 days before harvest. The safe interval between chlorhexidine WP and thiophanate-methyl WP is 5–7 days. Swallow Mn-Zn WP has a safe interval of 2–3 days. For agricultural WP used against certain pests, the safe interval is 4–5 days.
**Insecticides**:
Cypermethrin emulsifiable concentrate should have a 2–5 day interval before harvest. Bromomethrin requires a 2-day interval. Anti-Polycarb needs a 6-day interval. Fenpropathrin and fenvalerate emulsifiable concentrates require a 3-day interval. Euthion, Kungfu, Lesbian, and Duobao WP all have a 7-day safe interval. The safe interval for emulsifiable concentrate is 9 days.
**Acaricides**:
Bromo-broth ester emulsifiable concentrate has a 14-day safe interval. Turk WP should be used with a 7-day interval before harvest.
By following these guidelines, farmers can ensure that their crops meet safety standards and reduce the risk of harmful pesticide exposure for consumers. It’s important to always check the label instructions and local regulations to stay compliant and protect both public health and the environment.
