Fenclorim APPLICATIONS
Fenclorim Biochemistry Enhances the metabolism of pretilachlor in rice, which proceeds via glutathione conjugation. 

Fenclorim Mode of action:
Herbicide safener. Taken up rapidly by the roots of germinating rice seeds, and protects them from potential damage caused by pretilachlor.

Fenclorim Uses:
Used as a safener for pretilachlor in direct-seeded rice.

Fenclorim Formulation types EC.

Selected tradenames: Mixtures: 'Sofit' (+ pretilachlor) (direct-sown rice) (Syngenta)
