Will the addition of a surfactant, spreader or wetting agent to a PyGanic spray solution increase the level of insect control I get?
A. We are aware of numerous studies that demonstrate tank-mixing certain types of these products with PyGanic will slightly increase the level of insect control. We have not seen enough information to recommend specific brands. Your best source of this type of information may be the manufacturer of the additive. As with any penetrant, wetting agent and surfactant, we recommend small scale testing be conducted in order to ensure these products will not injure your crops. Always be sure the spray solution is within the pH range of 5.5 to 7.0.
