The potential for rapid appearance of Asian soybean rust has many growers re-evaluating sprayers. Because fungicide application requirements differ from those of commonly used systemic herbicides (e.g., glyphosate), in most cases nozzles will need to be changed and the adequacy of pumps, booms, and other plumbing system components will need to be checked. Due to lack of Midwestern experience in foliar fungicide application into the soybean canopy, current recommendations are based on other fungicide application work or experience in South America.
