Heat Canker in Wheat, Barley, and Oats

Jun 05, 2019

The last couple of days the weather has given us some dry sunny weather with high winds. This has been great to have fields finally dry off and make strides with planting any remaining acres. Unfortunately, this also exposed young small grain seedlings to the same conditions. The daytime heat at the soil surface has caused heat canker. The tender young tissue at the soil surface basically has been ‘cooked’ and this appears as a yellow band that is slightly constricted (Photo 1). As the leaf continues to grow, this yellow band (1/8 - 1/4") moves upward and away from the soil surface. If the hot and dry weather lasts for several days, repeated bands can become visible. Because of the high winds, the tips of leaves may break off at the yellow band and give a field a very ragged appearance. Damage from heat canker is temporary and should not affect further growth and development.

Video: Agriculture Secretary Rollins Speaks at American Farm Bureau Federation Convention in Anaheim

One of the highlights at the 2026 American Farm Bureau Federation Convention in Anaheim, California, was an address by U.S. Secretary of Agriculture Brooke Rollins. During her remarks, she thanked America’s farmers and ranchers and said the Trump Administration is fully aware that food security is national security.

She also acknowledged the challenging times in Farm Country with low commodity prices and high input costs and said that’s why the President stepped in to help with the recent Bridge Assistance Program.

Montana Farm Bureau Federation Executive Vice President Scott Kulbeck says that Farm Bureau members are appreciative of the help and looks forward to working with the American Farm Bureau Federation and its presence in Washington, DC to keep farmers and ranchers in business.

Secretary Rollins said the Trump Administration is also committed to helping ranchers build back America’s cattle herd while also providing more high-quality U.S. beef at the meat case for consumers.

And she also announced more assistance for specialty crop producers who only received a fraction of the $12 billion Farmer Bridge Assistance (FBA).

It’s important to note that producers who qualify for Farmer Bridge Assistance can expect the Farm Service Agency to start issuing payments in late February. For more information, farmers and ranchers are encouraged to contact their local USDA Service Center.
