Gnatrol® WDG Biological Larvicide is a new water dispersible granule formulation. Gnatrol WDG offers the same effective control of fungus gnat larvae as the original Gnatrol Biological Larvicide, but with increased convenience and application accuracy for a variety of ornamentals as well as all bulb crops, bedding plants and vegetable sets. 16 pound container.
Note: Product will not control adult fungus gnats.
- Ease of Use- Gnatrol WDG's water dispersible granules make it much easier to measure and mix. The new formulation is also much more concentrated, meaning less product packaging in the greenhouse.
- Increased Shelf Life- Gnatrol WDG's shelf life has been extended to two years, compared to the original formulation's one year shelf life.
- OMRI-listed- Gnatrol WDG is listed for organic production by the Organic Materials Review Institute (OMRI).
Light Fungus Gnat Infestation Rates: 3.2 to 6.4 oz per 100 gallons
Heavy Fungus Gnat Infestation Rates: 13 to 26 oz per 100 gallons
Note: Gnatrol WDG comes in a 16 pound pail. 16 lbs = 10 gal or 1.6 lbs = 1 gal
Application Timing: Gnatrol WDG only controls larvae, so applications must be made when larval stages are present. When all life stages are present (eggs, larva, adult), make weekly applications for 3 weeks at 13 to 26 oz per 100 gallons.
