A small portable sprayer was found to be the most practical for applying experimental herbicides for the control of lambkill (Kalmia angustifolia L.) in lowbush blueberry plots. The standard knapsack sprayer requires a large volume of rinse water to clean the sprayer between treatments and this frequently has to be transported a considerable distance to the spray site. In order to reduce the amount of rinse water to a minimum a knapsack sprayer was modified so that the spray solution for each treatment could be held in an individual disposable polyethylene bag.
