Fusarium seedling blight

Causal organism  - Mainly Microdochium nivale  


Hosts

The most common symptom of a serious attack of Fusarium seedling blight is very poor plant establishment, i.e a very thin crop. This occurs because of pre-emergence and post-emergence seedling blights - the most important phase of the disease.

Root rotting, brown foot rot and leaf blotching (usually following some other form of damage), glume blotch and ear blights can all be caused by true Fusarium species. Severe foot rot, usually affecting plants under stress (especially moisture stress) can result in premature ripening and 'whiteheads'. Under prolonged snow cover M.nivale can cause 'snow mould'.
