Product Description
NEMAforce™ HB is the beneficial nematode Heterorhabditis bacteriophora, used to control soil-dwelling grubs and root pests. It is a “cruiser” that prefers to live well below the soil surface and actively seeks out its hosts, which makes it a strong choice against deeper grubs like Japanese beetle larvae. The microscopic nematodes are harmless to people, pets, and plants, and fit into turf, nursery, ornamental, and field programs — including medicinal cannabis.
What it targets
- Japanese Beetle, June/May Beetle, and other white grubs
- Apple Maggot pupae and leafminer pupae
- Cabbage Root Maggots, Onion Maggots, Carrot Rust Flies, Carrot Weevils
- Cucumber Beetle larvae, Flea Beetle larvae, Northern Corn Rootworms, Wireworms
- and many other soil-dwelling pests
Crops it supports
Soft fruits, turf and lawn, tree and shrub nurseries, and ornamentals — in greenhouses, indoor facilities, medicinal cannabis, fields, and gardens.
How the nematodes work
Infective juvenile nematodes penetrate the host through its natural openings. Once inside the body cavity, they release a symbiotic bacterium that kills the host insect within 24–48 hours. The nematodes grow and multiply inside the dead host, and a new generation of infective juveniles then leaves it in search of more pests.
