Several herbicides were used for control of weeds in Jersey Orange sweet potato plantings on a sandy loam soil at Hammonton, New Jersey, during 1960, 1961, and 1962. The treatments were applied preemergence to the weeds at transplanting of the crop. Data included crop injury scores, level of weed control, effects on yield, influence on internal root color and flavor, and effects on sprouting.
Excellent control of germinating annual weeds was obtained with 3-amino-2,5-dichlorobenzoic acid (amiben), 2,6-dichlorobenzonitrile (dichlobenil), N,N-dimethyl-2,2-diphenylacetamide (diphenamid), and dimethyl 2,3,5,6-tetrachloroterephthalate (DCPA). These herbicides had no adverse effects on yield, quality factors, or growth.
