Vomitoxin is showing up in pockets of the durum wheat crop in North Dakota.
High humidity and abundant moisture created the perfect conditions for the disease to thrive.
Keith Deutsch, a North Dakota farmer, encountered problems with the fungus last year, and is considering leaving wheat out of his rotation in 2017 because of the large discounts taken from durum with high vomitoxin levels.
“We’ll just have to raise something else besides durum,” said Deutsch. “We’ll have to raise soybeans or something different. I have a pretty good variety that seems to be resistant to the scab.”
North Dakota grows half of the durum crop in the United States. Despite the issues with vomitoxin, NASS says 80 percent of the state’s durum crop is rated good to excellent.
