How CLINCHER Works
CLINCHER 100 EC contains cyhalofop-butyl, a selective herbicidal active ingredient belonging to Herbicide Group 1. It is primarily used as a post-emergence treatment against susceptible grass weeds.
After application, cyhalofop-butyl is absorbed by susceptible weeds and interferes with their normal growth, eventually resulting in cessation of growth and weed death. Its selectivity allows it to control susceptible grass weeds while providing tolerance to rice when applied according to the registered directions.
Target Weeds
CLINCHER 100 EC is registered for controlling grass weeds in rice. The Corteva Philippines product information specifically identifies:
- Telebisyon (Echinochloa crus-galli)

The Philippine rice pesticide reference also lists the product for grasses in direct-seeded rice.
