WebMechanism of Action. In target plants, prometryn inhibits the electron transport at the photosystem II receptor site (Hills reaction) in photosynthesis and oxidative phosphorilation. Plants affected by prometryn at first develop yellow leaf edges and interveinal chlorosis (pronounced on older foliage and to a lesser extent on younger leaves). The Hill reaction is the light-driven transfer of electrons from water to Hill reagents (non-physiological oxidants) in a direction against the chemical potential gradient as part of photosynthesis.
