Since Demand Duo already contains active ingredients from 2 different classes, Group 3A (Lambda-cyhalothrin) and Group 4A (Thiamethoxam), tank mixing Bifenthrin (Group 3) would not be recommended as it has the same mode of action as the Lambda cyhalothrin. Please view the product label for more information.
