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...

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 moisture must not be too high and there must be no standing water in the field, otherwise herbicide injury easily occurs. After the wheat emerges, isoproturon plus bensulfuron-methyl can be used for soil sealing treatment.
