Generally, it will die within 20-25 days, but in the case of low temperature, it will take longer for some perennial weeds.The drug effect was good before 4 leaf stage after bud, but decreased when seedling was large.The drug had the herbicidal activity before bud, but the activity was lower than that after bud.
