There have been some extremely high temperatures during the last week in Kansas. While this is not unusual for this time of year, the high temperatures have caught some of the wheat during the grain filling period. Read more from Wheat Specialist Romulo Lollato in this article.
The month of June has been hot across many locations in Kansas. The combination of heat and drought stress during certain growth stages in corn can be problematic. Read more from Cropping Specialist Ignacio Ciampitti and the Kansas Climate team.
Summer temperatures have arrived across Kansas, with expected highs reaching near or exceeding 100 degrees in the coming days. Under these conditions, producers need to be aware of certain considerations when applying herbicides.
The Climate Prediction Center and the National Weather Service have issued heat outlooks for the weekend and continuing through the end of July. Even western portions of Kansas can expect elevated dew points and increased low temperatures.
Recent high temperatures occurred at a particularly critical period for the Kansas corn crop. Temperatures last week were unfavorable for a significant portion of Kansas. Heat stress during critical stages could lead to yield reductions.
With many regions in Kansas reaching temperatures over 100 degrees this week, producers are encouraged to keep in mind how hot temperatures may impact the effectiveness of herbicide applications.
Monitoring summer heat stress is important to ensure healthy livestock. Don't forget about the Animal Comfort Tool, a very useful tool from the Kansas Mesonet. Learn how to find and use this resource in this article.
The month of July started off relatively cool for Kansas. However, the end of the month looks to be considerably hotter. The National Weather Service is forecasting excessive heat for much of Kansas next week. Learn how to be prepared and who is most vulnerable.
Wheat is generally sensitive to unusually high temperatures at nearly every stage of growth, being more sensitive in the reproductive stages. Both daytime high and nighttime low temperatures have been extremely high across parts of Kansas during the four-day period May 9-12. Extreme heat in early- to mid-May occasionally happens. To have four consecutive days of days with highs in the low- to mid-90s F at a time when much of the state’s wheat crop is either in the heading or flowering stage is concerning.
This year started off with statewide below-normal temperatures through April. With the dry conditions experienced through this period, the cool temperatures helped mitigate drought expansion and water demands. However, May has brought a turn to much-warmer-than-normal temperatures for Kansas thus far. With our lack of previous warmth, our bodies haven’t had an opportunity to adjust and it has brought on numerous additional stressors.
There are certain factors to consider when making herbicide applications during extremely hot weather. Plant response can vary depending on the herbicide and other plant growth processes. Herbicide volatility increases in some products when temperatures get very warm outside. Learn more in this article.
