Wheat plants infected with wheat streak mosaic virus.

Volunteer Wheat and Kochia Management With Herbicides Will Likely Require Two Passes

Wheat curl mites, which carry wheat streak mosaic virus, use volunteer wheat and grass weeds as secondary hosts to infest recently planted winter wheat crops. Therefore, effective management of these plants before winter wheat planting is critical.

Three chokecherry trees exhibiting various x-disease symptoms on their foliage.

X-Disease in Chokecherries

X-disease is the name given to a set of diseases caused by a strain of the bacteria “Candidatus Phytoplasma pruni” that primarily affects stone fruits. Infected plants will typically display yellowing or reddening of their leaves by mid summer.

Bean Leaf Beetles Showing Up in Soybean

Despite the prediction of low overwintering survival we have observed bean leaf beetles in soybean this week. See our latest observations and management recommendations.

Corn leaf with trace amounts of tar spot.

Tar Spot Confirmed in South Dakota

Trace amounts of tar spot were recently found in Yankton and Bon Homme counties and are thought to have originated from corn residue instead of windblown spores. This speaks to the importance of crop rotation in the management of this disease.

How to Properly Launder Pesticide Contaminated Clothing

Many types of personal protective equipment are intended for single use only and should be discarded after use, but how do you wash reusable equipment and clothing contaminated with pesticide residue?

Keep Watch: Wheat Streak Mosaic Virus is Developing in South Dakota Fields

Wheat Streak Mosaic Virus has been reported in South Dakota wheat fields and is also a major wheat disease for Great Plains states in 2025. The virus is sweeping across the state and is rampant in winter wheat.

Examples of three commonly used protective gloves used for pesticide applications.

Pesticide Personal Protective Equipment: Glove Selection

Safety gloves are one of the most-important pieces of pesticide personal protective equipment. Glove material is very important, as not all materials provide the same protection for different pesticide ingredients.
