Question of the Week

Last week the question was:  What is wrong with these wheat heads?


These wheat heads are showing symptoms of Fusarium head blight.  Fusarium overwinters on the debris of host plants and then is spread by rain spash or by wind.  Once a head is infected it dries down prematurely causing the bleaching seen in the picture above.  Fusarium is a troublesome disease because it creates a mycotoxin that is toxic to humans and domestic animals.  The most effective ways to manage Fusarium head bight include using resistant cultivars and good rotation practices.  For more information, take a look at this APS page.


Here is this week’s question:  What are these?  Hint:  If they were bigger, you could make an omelette.
