When it comes to spraying pesticides, think of the pest as the bull’s-eye on a target. The application will get the highest scores when the right rate of the pesticide is delivered directly to the center of the bull’s-eye. But if the relationships between water, the leaf surface and pesticide are off or if the applicator has poor equipment, the application won’t likely be on target. Fred Whitford shares how using adjuvants can help redirect those spray droplets back to the “bulls-eye,” even if the application was marginally acceptable. The clinical engagement professor for the Purdue Pesticide Programs explains how adjuvants can improve the biological performance of the pesticide.
