Gnatrol Biological Larvicide
Water Dispersible Granules
Once the larvae have ingested Gnatrol, they become paralyzed, stop feeding immediately and die--usually within 24 hours. This water dispersible granule (WDG) formulation will not leave a residue and is easier to measure for increased application accuracy.
Gnatrol WDG is listed by the Organic Materials Review Institute (OMRI) for use in organic production.
Rate of use: for light infestations, 3.2-6.4 oz./100 gallons, applied as a soil drench. For heavy infestations, 13-26 oz./100 gallons, applied as a soil drench.
Active ingredient: 37.4% Bacillus thuringiensis, subsp. israelensis, strain AM 65-52 fermentation solids and solubles
Gnatrol 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.
