Xanthomonas confirmed in Colorado; farmers encouraged to be on the lookout for corn disease
Crop experts are telling Colorado farmers to be on the lookout for disease symptoms in corn caused by the bacterium Xanthomonas vasicola pv. vasculorum (Xvv) — a disease that’s new to Colorado, or perhaps has just gone undetected in recent years.
In a recent press release, USDA officials stressed that it presents no health risks to people or animals. USDA also does not consider this plant disease to be of quarantine significance for domestic or international trade, and intends to address it like any other bacterial disease of corn. Read the full news release here.
While there’s no evidence of lost yields due to Xanthomonas (pictured above), there is the potential for lost yields if the disease is not managed properly. Ongoing research in Colorado and Nebraska will assess the impact of the disease on yields.
Dr. Kirk Broders, who leads the Crop Pathology Lab at Colorado State University, is one of the lead contacts nationally on this issue, and encourages farmers who see symptoms of Xanthomonas to contact him at (970) 491-0850, or firstname.lastname@example.org. Broders also has more information posted on his Broders Lab website.
Dr. Broders is working with the Colorado Corn Administrative Committee (CCAC) to conduct a corn disease survey during this growing season, in a collaborative effort to compile comprehensive information regarding all corn pathogens and enhance future mitigation efforts. Please contact Dr. Broders if you’re willing to assist in surveying fields. The diagnosing costs will be covered, thanks to funding from CCAC.
Colorado Corn, based in Greeley, is made up of the Colorado Corn Growers Association and Colorado Corn Administrative Committee. The Colorado Corn Growers Association (CCGA) is comprised of dues-paying members who are politically active, focusing on policy that impacts corn producers and agriculture in general. The Colorado Corn Administrative Committee (CCAC) oversees how Colorado’s corn check-off dollars (one penny per bushel of corn produced in the state) are spent on research, market development, outreach, education and other various endeavors.
