The consumer size of TERRANEM contains 50 million beneficial parasitic
nematodes (Heterorhabditis bacteriophora) in a clay/gel carrier.
This package will treat a surface of up to 2500 ft² or 230 m². (Adjust the rate
according to the level of infestation)
How beneficial nematodes work
Beneficial nematodes search actively in the soil for white grub larvae. Once
found they enter the white grub through any natural opening in the body and
release a bacteria in the grub which causes it to die. These bacteria multiply
very rapidly and transform the body of the dead insect into food for new
nematodes which are multiplying in their host. These new nematodes leave the
body of the dead grub and search for new larvae to infect and kill.
Controls the larvae stage of several white grub species including the
following: European chafer, common chafer, Japanese beetle, Asiatic beetle, May
and June beetle, black vine weevil, strawberry root weevil and other insect
pests that live in the soil.
Although beneficial nematodes can be applied any time pest larvae are present and soil temperatures are above 12-14 degrees centigrade, late summer and early
fall is the ideal time for application. The grub larvae are vulnerable as they are small, thin-skinned and near the surface feeding on grass roots.
In Western Canada this application takes place earlier due to the warmer climate. Application times run from mid to late July into August for best results.
