Temperature influences the performance of burndown herbicide applications
Poor grass control from spring burndown applications has been reported across Kansas, with cool April temperatures likely to blame. Glyphosate performance suffers without active weed growth. Learn how weather, tankmixes, and herbicide rates may have contributed to reduced control this season.

Controlling volunteers in a soybean/cotton crop rotation
Volunteer soybeans in cotton, or volunteer cotton in soybeans, can hurt yield, quality, and harvest efficiency. With over-the-top dicamba use restricted in 2025, controlling these volunteers is more difficult, especially in herbicide-tolerant systems. This article outlines effective chemical and cultural strategies.
Control options for buckbrush, roughleaf dogwood, and smooth sumac
Buckbrush, roughleaf dogwood, and smooth sumac are widespread brush species in Kansas that can form dense clumps, reducing forage production in pastures and rangeland. These shrubs are generally avoided by cattle, making early identification and control important.
Soybean Gall Midge: What to watch for this season
Soybean gall midge, an emerging pest capable of causing significant yield losses, was confirmed in Kansas in 2023. This pest overwinters in Kansas and should be actively scouted for, especially near the Nebraska border. Learn how to identify soybean gall midge and what to watch for this season.
World of Weeds - Catchweed bedstraw
Catchweed bedstraw, a clinging annual weed common in Kansas hay fields, can reduce forage quality and complicate harvest. This article outlines how to identify the plant and provides herbicide options for effective control in smooth bromegrass meadows.
2025 Kansas Wheat Plot Tours - Updated schedule
K-State Research and Extension and the Department of Agronomy will kick off their annual winter wheat variety plot tours on May 13. Join us at a location near you to evaluate new and upcoming varieties and discuss agronomic performance and disease resistance. Details are being finalized for the June plot tours.
High levels of wheat streak mosaic virus in parts of Kansas in 2025
Over the last several weeks, symptoms of wheat streak mosaic virus have been showing up in wheat fields across Kansas, with increasing severity as temperatures warm. In this article, we answer some commonly asked questions about this complex of wheat viruses.
