Wheat head scab update

Reports from agfax.com show that head scab of wheat (Fusarium head blight) is appearing in southern regions of several states, including Illinois and Missouri.

Fusarium head blight affects crops by “bleaching” them in color; due to rainy conditions during the flowering of the plant, crops are especially susceptible this year. Not only the appearance of the plant is altered and yield losses more probable, but head scab can also produce mycotoxins.

In Illinois, agfax.com reports “moderate to high incidence of scab.” Naturally, there are differences from field to field, which are results of plant varieties, the possible application (or lack thereof) of fungicide and differing local weather conditions.

In Missouri, many fields in the southeast portion of the state are infected.

Researchers suggest evaluating and observing the disease prior to maturation; those with high levels of scab “should consider making adjustments to their combine that would allow low test-weight, scabby kernals to be blown out the back of the combine.” Click here for information on combine fan speed statistics from The Ohio State University.
