Harmonix Tri-Nema

A blend of 3 entomopathogenic nematodes for use in the control of leatherjackets and chafer grubs (at the time of egg laying and up to their second instar stage). It consists of the 3 nematode types: Hunters cruiser nematodes which seek out to kill their prey (Heterorhabditis bacteriophora); Resident sit and wait nematodes which wait until grubs encroach into their vicinity to kill them (Steinernema carpocapsae); and Explorers which apply intermediate foraging actions between the other two nematode types (Steinernema feltiae).
