Pre-emergence herbicides for wheat

Pre-emergence herbicides with residual activity are used less frequently in wheat production compared to other cropping systems in Kansas. However, residual herbicides applied prior to wheat emergence can be part of a good weed management system in wheat production.

Nitrate toxicity in drought-stressed corn

Drought-stressed crops such as corn and sorghum tend to accumulate high levels of nitrate in the lower leaves and stalk of the plant. It is wise for producers to test their drought-stricken forage prior to harvest.

Does grazing cover crops impact soil properties?

Integration of cover crops into no-till crop production has been recommended to regenerate soils degraded after many years of conventionally tilled, low-intensity cropping systems. A recent study investigated cover crop grazing impacts on residue return and key soil properties in west central Kansas.

First reports of sugarcane aphid on grain sorghum in Kansas

The sugarcane aphid has been reported in three counties in Kansas. Grain sorghum producers in Kansas should be scouting on a routine basis, especially late-planted fields. Early detection is key, but treatments should be based on established thresholds.
