Vegetables can be eaten a few days after spraying

1. How many days can vegetables be eaten after spraying?

The key depends on what kind of pesticide is being used. If it is highly effective and low-toxic, it can be eaten 7-10 days after taking the drug; If it is moderately toxic, it can be eaten after 15 days after taking the drug; Vegetables that have been sprayed with high and high residue pesticides can not be eaten for a long time, such as: methamidophos, parathion (1605), methionphos (3911), carbofuran (carbofuran), monocrotophos, methylisosulfonphos, methocarb, hexacarb.

2. How to clean vegetables to be safe?

Usually the pesticide residue attached to the leaves will evaporate in five days to a week, but it is best to soak it in detergent for 10-15 minutes or in water for 30-60 minutes to be on the safe side. However, do not soak for too long to avoid the surface pesticides entering the water and returning to the inside of the fruits and vegetables.

With the continuous progress of cultivation technology, the growth period of vegetables has become shorter and shorter, and with the intensification of environmental pollution, the pests and diseases of vegetables are becoming more and more serious.

Leafy vegetables were heavily polluted by pesticides, among which leeks and rape were polluted in the largest proportion. Nightshade vegetables such as green peppers, tomatoes, etc., young pod vegetables such as beans, bulb vegetables such as onions, garlic, onions, etc., the pollution of pesticides is relatively small, but some are relatively large.

Finally, I would like to remind everyone: try to buy fruits and vegetables in the regular market with health supervision, and the product packaging has one of the four signs of "quality and safety", "pollution-free products", "green food" and "organic food", which is relatively safe and reliable.
