Pests in Wheat - In Crop
Root lesion and burrowing nematodes
Constraint – Root lesion and borrowing nematodes
- Nematodes are microscopic, parasitic, worm like creatures
Affected plants are stunted and tiller poorly, and may wilt despite moist soil
Roots may show browning, thinning, withering and lateral root reduction
Burrowing nematodes have similar effects, but are more likely to produce patches like those caused by rhizoctonia bare patch
- Losses in cereals can be between 5-15%, but individual losses as high as 40% have been recorded
Root-lesion nematode cannot be eradicated. Populations can be managed with crop rotations, control of green bridge hosts, ensuring plants have adequate nutrition, and avoidance of root-pruning herbicides. chemical control is not economical.
