Gnat Off 250ml
Fungus Gnats or Black Fly lay their larvae in the root zone of your plants. These larvae then burrow into the root zone to feed, carrying with them infections in their gut which multiply in the root zone, breeding disease. Fungus Gnat Off works by targeting a special enzyme in the gut of the larvae, killing them in the root zone thereby eradicating the problem. This 100% natural organic concentrate is diluted to mix into your reservoir. It does not effect beneficial nematodes, hypoaspis or orius.
