How to Choose Beneficial Nematodes
- 1). Inspect garden plants for signs of damage. If plants have fallen over and disconnected from the roots at the base of the plant while the roots remain in the ground, the likely predator is cutworms. Select S. capocapsae nematodes for control of cutworms and other surface feeding insects.
- 2). Observe lawn areas for signs of stress to the turf. Peel back irregular yellow patches of sod and look at the soil beneath the patch. If a large number of white grubs are beneath the patch of lawn they are likely the cause of the damage. Select S. glaseri nematodes to control white grub populations.
- 3). Examine moist areas of the yard for swarms of small gnats. The larvae of several types of gnats and flies lay their eggs in moist plant matter, and the larvae feed on roots, leaving plant growth stunted. Select S. feltiaeis nematodes for control of fungus gnats and other fly type infestations.
