What herbicide is used for pre-emergence weed control after sowing rapeseed? Please give an introduction.After sowing rapeseed and before seedling emergence, clomazone can be used for pre-emergence weed control. Clomazone can control a variety of annual grass weeds and broadleaf weeds, and is mainly used in rapeseed transplanting fields, where soil closure treatment is carried out before rapeseed transplanting.
Clomazone is usually mixed with acetochlor, which can improve the control effect on weeds such as speedwell that are difficult to control with acetochlor. When the seeds are well covered, using clomazone at a low dose after sowing and before seedling emergence in direct-seeded rapeseed generally does not cause herbicide damage.
Precautions:In direct-seeded rapeseed fields and rapeseed seedling beds, clomazone and acetochlor are applied after sowing and before seedling emergence for soil closure treatment, but the dosage must not be too large, so as to avoid whitening of rapeseed seedling leaves or even seedling death.
