Fusarium Ear Blight

A range of Fusarium species cause head blight in cereals

LOOK OUT FOR:

Parts of the ear dying and turning white

General discolouration of the ear

RISK FACTORS:

Wet, warm weather

Delayed harvest


The main symptoms are the death of part of the ear ranging from a single spikelet to a large part of the ear

Yield losses can be high, often in the order of 15-40%.

The mechanism whereby fusarium species infect the ear isn’t entirely understood but is likely to be due to the direct transfer of spores from crop debris to the ear through a combination of wind and rain.

The disease is favoured by warm, wet weather, especially heavy storms, during flowering

Economic losses can be severe through a combination of reduced grain size, poor grain quality
