size: (16 lbs.)

16 pound pail. 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. Gnatrol 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. Use 3.2 oz to 6.4 oz per 100 gallons applied as a soil drench for light infestations or use 13 oz to 64 oz per 100 gallons applied as a soil drench for heavy infestations. Active ingredient: Bacillus thuringiensis v. israelensis (BTI)
