How to use herbicides in vegetable fields safely? Master these key application points
Weeds in vegetable fields are a major problem in vegetable production. Hand weeding is both labor-intensive and backbreaking, so the vast number of vegetable growers need to use herbicides in vegetable production. However, vegetables come in many varieties, have short growing periods, high multiple-cropping indexes, and complex crop rotations, and there are also many types of herbicides. If used improperly, they can easily cause herbicide damage, or even total crop loss...

Why are insecticides prohibited during the lychee flowering period?
Experimental research and production practice have proven that placing bees for pollination during the lychee flowering period is the guarantee of a bumper lychee harvest, and the honey made by bees from collected pollen is also a natural health food for humans. In order to prevent bee poisoning and honey contamination, ensure that enough worker bees are out foraging for nectar, improve pollination effectiveness, and protect human health...

What is the best time to spray insecticide on rice?
Do not spray insecticide on rainy days; this is basic common sense that farmers understand. However, many farmers often spray at noon on sunny days, which is highly inadvisable and harmful, because: 1. At noon, the light is strong, and pests hide on the undersides of leaves and inside stems, so the insecticidal effect is poor; 2. Under high temperatures and strong light, the pesticide volatilizes and decomposes late...
