Present-day herbicide spraying of field row crops is very inefficient; over 75 percent of the herbicide is wasted as overspray, which is costly and contaminates the environment. The feasibility of efficiently applying translocatable herbicides with electrostatic spray deposition techniques will be examined. Studies will evaluate different particle charging means, including induction charging, corona charging, and combinations thereof. Special emphasis will be placed on studying the efficacy enhancement of herbicides which appear to work better at higher concentrations.
