Gnatrol WDG Biological Larvicide – 16 Lbs.
Gnatrol Biological Larvicide
Water Dispersible Granules
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.
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
