Question of the Week – Loose Smut

Posted by romeethredge on April 17, 2015

Last week I had a photo of some oats with a black powdery look where the grain should be. This is a disease called loose smut. You’ll often see this disease in very very low levels. I’ve seen it at higher levels where someone saved their own seed for several years and didn’t use a systemic seed treatment.

It also occurs in wheat and here’s an excerpt from the UGA Wheat production guide about it.

“Loose smut causes the tissues in the head to be replaced by masses of powdery spores. The fungus spores invade the embryo of the developing seed and the fungus survives there until the seed germinates.  These smut pathogens are only transmitted by seed. Planting certified seed is an effective method to control smut diseases because seed fields are carefully inspected. Seed treatment with systemic fungicides is an inexpensive way to achieve nearly complete control of loose smut.”
