Soaking hop rhizomes in hot water—122° F for 10 minutes or 125° F for five minutes—kills nematodes and does not injure the rhizomes, according to tests at Davis. Fumigating hop yards before planting controls root-knot and dagger nematodes more effectively than side-dressing chisel applications. However, stock planted after fumigation must be free of nematodes.
