Abstract
Abstract Hexazinone was applied preemergent, after pruning, at 1.1, 2.2, 4.5, or 9.0 kg/ha to a commercial lowbush blueberry ( Vaccinium angustifolium Ait .) field. Visual ratings indicated a quadratic decline in grasses and a linear increase in blueberry injury associated with hexazinone application. Counts of weed populations showed a highly significant linear decline in meadowsweet ( Spiraea latifolia Borkh .) and goldenrod ( So-lidago sp .) with an increase in hexazinone rate. Hexazinone treatments did not affect the density of blueberry stems, but flower buds and yield followed a quadratic trend. Hexazinone provided excellent control of many common weed species accompanied by a significant increase in blueberry yield. Chemical name used: 3-cyclohexyl-6-(di-methylamino)-1-methyl-1,3,5-triazine-2,4(1 H ,3 H )-dione (hexazinone).
