When many farmers use **pesticides** to control pests and diseases, they often overlook the importance of the waiting period between pesticide application and harvest. This can lead to excessive pesticide residues on vegetables, which may pose health risks to consumers. To help farmers better understand safe practices, here are the recommended safety intervals for various pesticides as outlined by the Ministry of Agriculture’s Vegetable Pesticide Testing Institute.
For **fungicides**, chlorothalonil WP should be applied at least 7 days before harvesting. The safe interval between chlorhexidine WP and thiophanate-methyl WP is 5–7 days. Swallow Mn-Zn WP has a shorter interval of 2–3 days, while agricultural WP used for killing pests and AIDS WP requires a 4–5 day gap.
In terms of **insecticides**, cypermethrin emulsifiable concentrate should be applied no later than 2–5 days before harvest. Bromomethrin has a 2-day interval, while anti-Polycarb needs 6 days. Fenpropathrin, fenvalerate, and other emulsifiable concentrates have a 3–5 day interval. Euthion, Kungfu, Lesbian, and Duobao WP all require a 7-day wait. Meanwhile, some products like emulsifiable concentrate need up to 9 days before harvest.
For **acaricides**, bromo-broth ester emulsifiable concentrate should be used with a 14-day interval, while Turk WP requires a 7-day waiting period.
By following these guidelines, farmers can ensure that their crops meet safety standards and reduce the risk of harmful pesticide residues. It's important to always check label instructions and local regulations to maintain both crop quality and consumer safety.
