How RICEMAX ULTRA Works
RICEMAX ULTRA contains cyhalofop-butyl and bispyribac-sodium, which provide complementary activity against susceptible weed species.
Cyhalofop-butyl is primarily active against susceptible grass weeds, while bispyribac-sodium provides activity against a broader range of weed types, including susceptible grasses, broadleaf weeds, and sedges.
The combination is designed to provide broader weed-management coverage in direct-seeded rice.
Effectiveness depends on weed species, weed growth stage, crop condition, application timing, and resistance status.
