Product Overview
Calibre® Max SX® contains thifensulfuron-methyl and tribenuron-methyl, sulfonylurea (ALS inhibitor) herbicides which work mainly by contact action and is most effective if applied when the weeds are small and actively growing.
Good spray cover of the weeds must be obtained for best results. Susceptible plants cease growth almost immediately after application and symptoms can be seen about two weeks after application.
Weed control may be reduced when soil conditions are very dry. Rain within four hours of application may reduce the effectiveness of the product.
