AQUABAC FG
Apply Aquabac fg to ornamentals, vegetables or herbs growing in greenhouse or nursery areas for control of fungus gnat larvae when larvae are present in the soil or potting mix. Also make applications to areas under benches and greenhouse floors where fungus gnats breed. For light infestations, use 8-16 fl. oz. of Aquabac fg/100 gal. of water (0.5-1.0 tsp. of Aquabac fg/gal. of water); for heavy infestations, use 32-64 fl. oz. of Aquabac fg/100 gal. of water (2-4 tsp. of Aquabac fg/gal. of water). Apply as a drench to sufficiently wet the surface of the growth medium where larvae are present.
Where heavy infestations (adults, eggs, pupae and larvae) are present, reapply weekly. Routine use of lower rates will keep populations to a minimum.
Even though Aquabac fg is not known to be phytotoxic to plants, it has not been tested against all plant species. Check on several plants before wide-scale usage.
