Name of Active Ingredient: Gliocladium virens GL-21
OPP Chemical Code: 129000
Gliocladium virens GL-21 is a fungus that is found in many kinds of soil throughout the United States. As a pesticide ingredient, the spores of this fungus prevent harmful fungi from infecting roots and other parts of plants. Gliocladium virens GL-21 is used only to prevent disease. It does not control pathogenic fungi after a plant is already infected.
No harmful effects to humans are expected from handling or breathing this fungus, or from eating treated food. To prevent possible eye irritation to workers, applicators are required to use protective eyewear.
Environmental risks are not expected. Gliocladium virens GL-21 occurs naturally in many kinds of soil. Its use in pesticide products is not likely to increase exposure of wildlife, fish, or other organisms. The fungus does not persist in soil; a few weeks after being added to soil, the levels return to the usual background levels. Body temperatures of mammals and birds are too high to support growth of Gliocladium virens GL-21.
