The use of minimum tillage plus herbicides in potato production

Abstract

There has been a marked increase in the use of herbicides in potato production. In many cases growers have simply added herbicides to their existing weed control program with little or no reduction in tillage. On Long Island six or more separate mechanical operations may be used by growers to control weeds.

The current paper summarizes 3 years’ results with various tillage — herbicide combinations carried out under widely varying levels of weed infestation. Under conditions of low to moderate infestation good results were obtained with one to two tillage passes plus the use of an herbicide. The use of an incorporated herbicide such as EPTC plus a single hilling operation as early as ground-brack was satisfactory. Greening of tubers was not appreciably increased by this or other early hilling practices. Fields with severe weed infestations required two to three tillage treatments plus an herbicide application. No yield reduction occurred from these treatments, with some indication of a trend in the opposite direction.
