Abstract
The results of the investigation and field trail indicated that there are 147 kinds of weed in Guizhou tobacco field, belonging to 29 families, treated soil with 75 g/667m~(2) of 50% napropamide before budding after 30 days and 45 days, the control effect to the weeds of the grass family reached respectively 83.66% and 88.79%. The control effect of large area trail also reached above 80%. But the control effect of this weedicide wasn’t very good to the broadleaf weeds, its average (control) effect was about 50%. 50% napropamide is safe to control weed in tobacco field.
