RESISTANCE MANAGEMENT
Serenade MAX has a unique mode of action and fungicide group (Group 44), which makes it very difficult for diseases to develop resistance. Serenade MAX can help with resistance issues by preventing diseases from developing ways to combat single site synthetic products. Serenade MAX works best when used in a program approach with other chemistries throughout the growing season to decrease the chance of resistance for all products on that particular crop.
