The Science
Gamma is powered by a new active ingredient called Tergeo®, a 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.
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.
Primary Crops
Grapes
Field trial data
In more than 700 North American product development trials and regulatory studies, the active ingredient in Gamma has demonstrated high performance ratings in burndown efficacy.
As a new directed postemergence application tool in grapes, Gamma can be used alone or in combination with a variety of herbicides. Extensive research has shown that Gamma can boost the effectiveness of other products in the tank, providing the additional power needed to knock out weeds that other herbicides may be missing.
