Gnatrol WDG Biological Larvicide — 16 lb Pail
Gnatrol WDG is a highly selective biological larvicide from NuFarm formulated with Bacillus thuringiensis israelensis (Bti) strain AM 6552 for control of fungus gnat larvae in commercial greenhouse and nursery production. Once larvae ingest Gnatrol, they become paralyzed, stop feeding immediately, and die — usually within 24 hours.
The water dispersible granule (WDG) formulation is easier to measure and mix than the previous liquid formulation, leaves no residue, and offers an extended shelf life. OMRI listed for use in organic production.
