Symptoms
- The fungus attacks the crop from seedling to milky stage in main field
- Symptoms appear as minute spots on the coleoptile, leaf blade, leaf sheath, and glume, being most prominent on the leaf blade and glumes.
- The spots become cylindrical or oval, dark brown with yellow halo.
- The several spots coalesce and the leaf dries up.
- The seedlings die and affected nurseries can be often recognised from a distance by scorched appearance.
- Dark brown or black spots also appear on glumes leading to grain discoloration.
- It causes failure of seed germination, seedling mortality and reduces the grain quality and weight.
