Root-knot nematodes (Meloidogyne spp.)
Field symptoms are typically of stunted, poorly growing plants with yellowing leaves. They may cause also wilting and death of plants particularly in hot weather. Roots of affected plants are distorted, swollen and show characteristic knots or galls.
- Plant resistant varieties, where available.
- Rotate for at least 3 to 4 years with cereals.
- Use bio-products (e.g. neem extracts). Some are commercially available for nematode control.
