Entomopathogenetic nematodes are regularly used in greenhouses and grow rooms to control multiple pest species like fungus gnats, shoreflies, thrips, and caterpillars. The most common species used in greenhouses are Steinernema feltiae and Steinernema carpocapsae.
When larva or pupal stages begin to occur in the grow medium.
Soil Temperature: 14-33C or 57-91F
Do not apply with chemicals. Nematodes are susceptible to various pesticides.
All filters should be removed, especially if finer than 0.3mm (50 mesh).
Use a maximum pressure of 20 bar/290psi at nozzle.
Spray nozzle should be at least 0.5mm(500 microns - 35 mesh).
Avoid sprayers equipped with centrifugal or piston pumps.
Nematodes enter their pest and release symbiotic bacteria into the larvas body cavity. This bacteria converts the host tissue into a food source, on which the nematodes feed, develop, and reproduce on. The bacteria then kills the pest within a few days.
