It’s that time of year again. It's the time of year for our wheat to start flowering, so fungicide applications should be top of mind. With the kind of spring we are experiencing throughout much of the Midwest, many factors favor Fusarium head blight (head scab) onset.
Remember, timely applications of triazole containing fungicides at Feekes 10.5.1 can help you mitigate your risk of the mycotoxin DON (vomitoxin) that is often times associated with head scab.
Last, but not least, do not use strobilurin fungicides as they can actually increase the levels of DON in your wheat fields. If you would like to evaluate your current risk of head scab, click here now.
There are two fungicide products that have earned PFR Proven™ status in wheat. Caramba® has shown a 6.7 Bu./A. yield increase and a $20.73/A. ROI in 7 years of multi-location data. Proasaro®421 SC delivered an average yield increase of 5.6 Bu./A. with a $15.40/A. ROI in 5 years of multi-location data.
It will be interesting to see what Miravis® Ace, a new SDHI mode of action combined with a triazole, can do for head scab control. Maybe someday it will even earn PFR Proven status as well!
