Non-Chemical Management
- Hand-pick and kill night-feeding adults, when practical.
- Cultivate future planting sites in the fall to reduce numbers of overwintering root weevils.
- Control weeds in and around plantings. Weeds may serve as other hosts for root weevils.
- Apply beneficial nematodes which kill weevil larvae. The nematodes are used as a soil drench in moist soils over 55 degrees F (mid-fall in western Washington). Read and follow the label directions carefully.
