Water Dispersible Granules

Gnatrol WDG Biological Larvicide is a highly selective, biological larvicide for use in greenhouses to control fungus gnat larvae. It may be used on a wide variety of ornamentals, as well as all bulb crops, bedding plants and vegetable sets. Once the larvae have ingested Gnatrol, they become paralyzed, stop feeding immediately and die—usually within 24 hours.

 Gnatrol WDG Biological Larvicide is now available in a water dispersible granule (WDG) formulation that will not leave a residue and is easier to measure for increased application accuracy.

 Gnatrol WDG Biological Insecticide provides fungus gnat control equal to the previous liquid formulation but in an easier to use granule formulation that is OMRI listed.
