Trigger

Trigger is a systemic post-emergence herbicide containing 500 g/kg tribenuron-methyl, a sulfonylurea (ALS inhibitor), formulated as water-dispersible granules. It controls a broad spectrum of annual and some perennial broadleaf weeds — including biotypes resistant to 2,4-D and MCPA — in winter and spring wheat, winter and spring barley, and tribenuron-tolerant sunflower hybrids. Apply from the crop's 2–3 leaf stage up to flag-leaf emergence, targeting young actively growing weeds and adding an alcohol-based surfactant.
