Wheat Harvest Challenged by Nebraska's Dry Conditions

Wheat Harvest Challenged by Nebraska's Dry Conditions

By Emily Diesing

Nebraska’s wheat harvest season is nearly complete. While the crop’s quality is high, it’s been a season of drought, freezes and disease.

Royce Shanemen leads the Nebraska Wheat Board, and says drought concerns began with the dry winter.

Then spring brought cold temperatures and illness to the crop.

“We did have a late freeze event that affected a lot of wheat especially in western Nebraska. Later in the season we saw different disease and insect pressures," Shaneman said.

“With our world wheat situation, the war in Russia and Ukraine certainly has an effect on the world market and then also that situation is reflected in some of our input costs and prices," he said.

White rot, also known as sclerotinia, is a common agricultural fungal disease caused by various virulent species of Sclerotinia. It initially affects the root system (mycelium) before spreading to the aerial parts through the dissemination of spores.

Sclerotinia is undoubtedly a disease of major economic importance, and very damaging in the event of a heavy attack.

All these attacks come from the primary inoculum stored in the soil: sclerotia. These forms of resistance can survive in the soil for over 10 years, maintaining constant contamination of susceptible host crops, causing symptoms on the crop and replenishing the soil inoculum with new sclerotia.
