With wheat harvest now under way in Ohio, sampling and testing for vomitoxin in head scab-infected wheat is vital to prevent further losses and avoid potential health problems in humans and livestock.
Pierce Paul, an Ohio State University Extension plant pathologist and small grains specialist, said that grain elevators will likely be testing every lot to ensure that any vomitoxin in infected grain stays below the acceptable limit of 2 parts per million.
“It’s important that the testing be conducted correctly to avoid overestimating or underestimating vomitoxin in the grain,” Paul said.
Wheat in some portions of Ohio is experiencing upwards of 60 percent incidence of head scab — a disease that attacks the wheat during flowering under wet, humid conditions. The disease can impact yields. In addition, the fungal pathogen that causes head scab produces several mycotoxins, including vomitoxin, that affect grain quality. Feeding infected grain to livestock can be harmful, and using infected grain for bran, flour and germ can be unhealthy for human consumption.… Continue reading
