Gnatrol offers highly selective, effective control of fungus gnat larvae, especially for those growers concerned with worker safety, the environment and resistance management.
- Effectively controls fungus gnat larvae
- Easy to use
- Gnatrol is OMRI-listed for organic production
Apply Gnatrol WDG with adequate water by soil drench to sufficiently wet the soil surface above and under benches where larvae are found. Areas under benches should be treated at high rates as this is one of the primary breeding areas. Reapply as needed. In situations where all life forms (eggs, larvae, pupae and adults) are present, such as with existing infestations, make three (3) weekly applications at the suggested range rate for heavy infestations. Regular follow-up applications using the suggested light infestations rates, will establish a long-term maintenance program.
For best results, apply drenches toward the end of irrigation period.
Gnatrol WDG is a larvicide and will not control adult gnats, therefore, application must be timed for a stage of development when larva are present in the soil.
Fungus gnat larvae generally respond to Gnatrol WDG treatment within 24 hours following applications.
RESTRICTIONS AND PRECAUTIONS
Gnatrol WDG is not known to be phytotoxic to ornamental plant species. However, since all ornamental plant species have not been evaluated, sensitivity to Gnatrol WDG should be checked on several plants prior to wide scale usage.
Important: Gnatrol WDG should not be injected in combinations with fertilizers or fungicides containing copper or chlorine, as this may neutralize the active ingredients. (Chlorine levels in potable water supplies should not present a problem with Gnatrol WDG performance).
DO NOT apply soil drenches to plants under stress or follow applications with excessive amounts of water.
