Steinernema kraussei

Type

Entomopathogenic nematode

Target pests

• Vine weevil

Notes

Often used at cooler temperatures for vine weevil larval control.

IPM positioning

Cool-condition nematode for vine weevil larvae.

Best deployment strategy

• Use for vine weevil larvae where substrate temperatures are cooler.
• Apply as a thorough drench; maintain moisture for several days post-application.
• Best used in a programme (repeat timing depends on risk and conditions).

Compatibility notes

• Works well with: Atheta coriaria as part of a broader vine weevil programme.
• Avoid: rapid drying and poor coverage; soil moisture is critical.

Environmental preferences

• Better suited to cooler conditions than many other nematodes used for vine weevil.
• Moisture is critical: evenly moist substrate before and after application.
