Nematode Solutions

Greehouses/Grow Rooms: When larva or pupal stages begin to occur in the grow medium.

Turf/Vegetable Garden:

• White Grubs (ON, QC) - Apply every year between end of August to the beginning of September when grubs are close to the top of the soil.
• White Grubs (BC) - Apply every year between mid-July to early August when grubs are close to the top of the soil.
• Crane Flies - Apply 2-3wks after the adults are visible on lawns where they are laying eggs. In most situations this would be in late July, August or early fall.

Soil Temperature: 14-33C or 57-91F

Nematodes are very susceptible to Ultraviolet Light (UV). Avoid spraying in direct sunlight.

Do not apply with chemicals. Nematodes are susceptible to various pesticides.

Greenhouses:

• 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.

Turf:

• Pre-irrigation and post-irrigation for 2wks after application enhances the nematodes efficacy.
• All filters should be removed on motorized sprayers, especially if finer than 0.3mm (50 mesh).

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.
