Plan now for volunteer corn control
Volunteer corn may or may not be considered a weed, but it does pose problems in some fields. One of the factors that makes volunteer corn management difficult is the prevalence of glyphosate and/or glufosinate resistance. There are some steps farmers can take early in the growing season to manage volunteer corn.
Effects of high temperatures on wheat
Wheat is generally sensitive to unusually high temperatures at nearly every stage of growth, being more sensitive in the reproductive stages than in the vegetative stages. High temperatures occurred when much of Kansas' wheat crop was either in the heading or flowering stages. This timing is a cause of concern and has resulted in many symptoms of heat stress
Check wheat heads for pollination problems
Many environmental conditions can cause pollination problems in wheat, such as freeze damage, drought, or heat stress. About 4 to 5 days after flowering, producers can begin checking their fields to see if their wheat successfully pollinated.
Possible causes for white heads in wheat
White heads have been appearing in many wheat fields around Kansas. Heads might be completely white starting from the stem or have just partial bleaching showing a few spikelets with discoloration. There are many causes of whiteheads which are discussed in this article.
Crop options after early terminated wheat
Cropping options to follow an early terminated wheat crop could be similar to those for full-season crops. At this point, viable crop options are still corn, soybeans, and sorghum. General agronomic considerations, herbicide carryover, and weed management are addressed for each crop in this article.
Kansas Wheat Crop Conditions: Summary of the 2023 Wheat Quality Tour
The 2023 Wheat Quality Tour took place May 15 - 18, 2023. Approximately 106 people actively scouted hundreds of Kansas wheat fields in 27 groups spread across six routes. The Kansas wheat crop is currently facing many challenges. This report summarizes the tour and gives an estimate of the overall production of Kansas wheat in 2023.
Corn rootworm egg hatch has begun in Kansas
Western corn rootworm resistance to Bt corn continues to be an issue in continuous corn in the United States. Evaluating corn roots for rootworm damage during the growing season is highly recommended. Eggs should begin hatching after approximately 380-degree days have accumulated. Learn more in this article.
