Abstract

Highbush blueberries [Vaccinium australe (Small), var. Colville] grown on a Leon sand at Chatsworth, New Jersey were treated with 3-(3,4-dichlorophenyl)-1,1-dimethylurea (diuron) and 2-chloro-4,6-bis(ethylamino)-s-triazine (simazine) each spring or each spring and fall from 1960 through 1966. The weed control obtained with diuron generally improved with continued use. At rates of simazine sufficient to achieve satisfactory control, the degree of weed control increased for the first 3 years and decreased the last 3 years. Diuron and simazine at rates sufficient to provide satisfactory weed control did not reduce the productivity of the blueberry plant. Palatability evaluations of off-flavor and sweetness of frozen blueberries, and objective measurements of pH and soluble solids, indicated that the diuron and simazine treatments did not affect any of these quality factors.
