The Valent Gnatrol WDG Biological Larvicide is best utilized in greenhouses for fungus gnat larvae management. It may be administered on a wide variety of ornamentals, as well as all vegetable sets, bedding plants and bulb crops. Once the larvae have consumed the solution, they become paralyzed; will stop ingestion immediately and die – usually within twenty four hours. Gnatrol is available in a water dispersible granule or WDG formulation that will not leave excess chemicals and will provide convenience in measurement for increased application efficiency. To apply, enforce the solution with adequate water as a soil drench. When all life stages are present (eggs, larva, adult), make weekly applications for 3 weeks at 13 to 26 ounce or 100 gallons. Gnatrol WDG only controls larva, applications must be made when larval stages are present. Product is OMRI listed. It may be used in certified organic production or food processing and handling according to the USDA National Organic Program Rule.
