Quick Guide: Controlling Vine Weevil
If you find vine weevil damage, tip the plant out and check the roots. Look for creamy-white grubs with brown heads, about 10mm long. Remove and destroy any you find. Re-pot the plant into fresh compost. If the roots are too damaged, cut the plant back to healthy stem and treat it as a cutting.
Control options include:
- Systemic Insecticide: Apply a proprietary systemic insecticide, especially for outdoor plants.
- Nematodes: Use parasitic nematodes (such as Steinernema kraussei) mixed with water and applied to moist soil. Soil temperature must be above 5°C for nematodes to work effectively.
- Trapping Adults: Place damp corrugated cardboard, polythene sheets, or wooden planks nearby to trap adults hiding during the day. Collect and destroy them.
- Monitoring: Use sticky barriers and pheromone traps to detect and reduce adult weevils.
Combining these methods gives the best protection against vine weevil damage.
