Plain Language Summary
Herbicides are an important tool in effective forest regeneration and aerial application is the most cost effective method for their use. In collaboration with colleagues from the United States and New Zealand, we developed a decision support system called SprayAdvisor that can be used on board spray planes or helicopters. It uses an electronic guidance system that takes into account local meteorological conditions to ensure uniform deposition and spatially accurate application. It can also allow for exclusion of sensitive areas as small as one hectare. Its use will ensure optimal targeting of herbicides to maintain cost effectiveness and minimize environmental effects. We conducted field trials under scenarios typical of potential use in Canada and found that it accurately predicted herbicide deposition. The SprayAdvisor decision support system is expected to become a component of best management practices for sustainable forest management and environmental protection in Canada.
