THE SCIENCE: HOW IT WORKS

Gamma is powered by a new active ingredient called Tergeo, a potent protoporphyrinogen IX oxidase (PPO)-inhibiting pyrimidinedione herbicide with a WSSA Group 14 classification.

PPO is an enzyme found in chloroplast and necessary for chlorophyll formation in plants. As a pyrimidinedione herbicide, Tergeo shuts down chlorophyll production and photosynthesis resulting in a rapid build up of reactive oxygen species and lipid per oxidation of the cellular membrane followed by quick herbicidal effects.

Tergeo is described as being fast-acting with herbicidal effects occurring 24 hours after treatment.
DELIVERING CLEANER VINEYARDS AND HIGHER YIELDS
A preeminent new tool for U.S. grape growers, Gamma will eliminate weed competition resulting in cleaner vineyards that maximize yield potential, crop quality and return on investment.

Gamma’s easy-to-use water dispersible granular (WDG) formulation with an ultra-low use rate minimizes environmental impact without compromising crop safety.
