"The drift potential of aerial herbicide applications by fixed wing aircraft and helicopter was investigated over a 13-year period in selected forest areas of coastal British Columbia. Depositions of liquid incubator chemicals and herbicides were monitored within and outside designated spray areas to determine the drift patterns of both types of aircraft. Spray deposition collection methods, flight paths, spray runs, layouts, herbicide formulations, pilot skill, and prevailing environmental conditions were found to affect the spray deposition patterns and drift potential during aerial applications. The implications of these findings to the management of pesticide use are discussed"--Abstract, page i. Issued also in print format. Includes abstracts in English and French. gccst Herbicides Canada.
