What pesticides are good to use during the cultivation of leafy greens?
There are many categories of pesticides used during the cultivation of leafy greens, including insecticides, fungicides, plant growth regulators, and so on. For example, at the peak period of leafy green caterpillar larvae, you can choose 20% Tianda diflubenzuron suspension concentrate at 800 times dilution, 50% phoxim emulsifiable concentrate at 1000 times dilution, or 90% trichlorfon crystal at 1000 times dilution for timely spraying, spraying 2-3 times.
When the leafy greens we buy taste of pesticides, it may be that the farmer sold the vegetables before the pre-harvest interval had passed. The pre-harvest interval means: after spraying, a certain amount of time must pass, generally 10 days—15 days, before they can be harvested.
1. How do you wash pesticides off leafy greens?
When cooking and stir-frying, washing leafy greens is essential, and it must be done carefully and meticulously to wash the leafy greens clean. Some people say to add soda or baking soda to the washing water; some say to add edible vinegar or table salt to the washing water; some say to add detergent to the washing water, and so on. None of these methods are good methods; none of them achieve the goal of washing off pesticide residues, and some even create new hazards. The best method is to soak and wash with clean water, which is reassuring and carries no risk of recontamination.
