How can weeds be effectively controlled during soybean cultivation?
How do you control weeds when growing soybeans? The main weeds in soybean cultivation include monocotyledonous weeds such as crabgrass, barnyardgrass, goosegrass, lambsquarters, and foxtail; broadleaf weeds include redroot pigweed, eclipta, copperleaf, and velvetleaf. Summer soybeans are usually sown in June, during the hot and rainy season, when weeds emerge aggressively, at high density, grow vigorously, and are diverse in species, easily forming a weed infestation. Generally, weeds begin to emerge 5 days after soybean sowing, and the entire weed emergence period lasts about 60 days, which is extremely unfavorable for high soybean yields. For this reason, accurately mastering chemical weed control techniques is crucial.

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 are the precautions for using insecticides during the melon seedling stage?
Melon seedlings are sensitive to many insecticides and are highly prone to pesticide damage, so insecticides must be used with extra care. For pests such as ground beetles, a moat method can be used: dig a small ditch around the seedbed, line it with waterproof plastic sheeting, then fill it with water and add Shennongbao or Amaier to form a barrier, which is very...

Can acetochlor be used for weed control during the wheat seedling stage?
Can acetochlor be used on wheat seedlings? Please advise: acetochlor must not be applied to wheat seedlings. Wheat is fairly sensitive to acetochlor from just emerging until before the 2-leaf stage, and applying the herbicide at this time easily causes herbicide injury. In wheat fields, acetochlor should be applied after sowing but before emergence, or after the wheat reaches the 2-leaf 1-heart stage. After application, keeping the field moist gives a better sealing effect; note that the soil...

How can non-toxic disinfestation be achieved during grain storage?
How do you carry out non-toxic disinfestation when storing grain? Please explain the methods. When storing grain, the high-temperature disinfestation method can be used. Generally, stored-grain pests can tolerate high temperatures of 35-40°C; under conditions of 46-48°C, sustained over a longer period, the pests can be killed, while above 50°C, the vast majority of pests will die within a short time...
