Know before you buy
WDG3000 features a high-concentration 3000 ITU/mg strain developed by Becker Microbial. This extra-strength formulation is specifically designed for high-potency soil drenching, making it more efficient for both active infestations and long-term prevention.
No, WDG3000 is an all-natural biological control that specifically targets fungus gnat larvae. It is safe for your plants, though it is recommended to replenish your beneficial microbes after treatment to ensure your soil ecosystem remains balanced and healthy.
This product is applied as a soil drench. Simply mix the water-dispersible granules into your irrigation water according to the dosage rates provided and water your plants thoroughly to ensure the solution reaches the larvae in the root zone.
The heavy infestation rate uses 7.5 grams per gallon to knock down large populations quickly. The preventative rate uses 1.8 grams per gallon, which is a lower concentration intended to maintain a protective barrier against future outbreaks.
Because of the high concentration, this container is extremely high-yield. Depending on whether you are using it for preventative maintenance or heavy treatment, it can produce hundreds of gallons of solution.
