Abstract
The formula of mixture was screened by pot-spray.The result indicated that the combination of desmedipham,phenmedipham and ethofumesate was good at ratio of 70 + 90 + 110 or 90 + 90 + 90.The six field trials showed that 21% EC was higher effective to control broad leaf weed and some grass weed at the dosage of a.i.1260-1680 g/hm2.This study was very useful to research and develop herbicides for sugar beet field.
