Spot Treatment of Granular Hexazinone in Wild Blueberries

open access: yesHortScience, 1998
Preemergence application rates of hexazinone have been reduced because of the concerns of it leaching into the groundwater. Spot treatments of a 10% granular fomulation of hexazinone, Pronone MG, would allow for selective post-emergence control of weeds not controlled by the reduced preemergence rate. For each weed species, St.
