Effects of recent high temperatures on wheat
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.
June heat in Kansas: High temperatures can stress livestock and corn
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.
Herbicide applications and high temperatures
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.

Heat wave for the weekend: Update on high temperatures and heat stress
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.
Critical timing in Kansas: High temperatures and corn development
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.
Herbicide applications and high temperatures
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.
Use the Mesonet Animal Comfort Tool to monitor livestock conditions this summer
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.
Heat safety awareness: Excessive heat forecasted for Kansas in late July
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.
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. 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.
Jumping Straight to Summer
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.
Herbicide applications and high temperatures
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.
High temperatures reduce effectiveness of Group 27 herbicides
Applying certain herbicides when air temperatures are high could reduce their effectiveness on controlling Palmer amaranth. Research conducted at K-State described two key changes about how Palmer amaranth responds to applications of mesotrione (Callisto) under high temperatures.

How hot has it been in Kansas this summer?
July is typically the hottest month in Kansas, and this year has been no exception. But, has this summer been hotter than normal? How does it compare to previous summers? This article examines measured summer temperatures from 40 locations all across Kansas.
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
Herbicide applications and high temperatures
Warmer temperatures are in the forecast for the latter part of June across Kansas with warmer-than-normal temperatures expected for July. Some considerations should be taken during hot weather when making herbicide applications to help ensure the best response.
Extreme heat and Kansas farm income
Moderate or severe drought is prevailing through much of the Corn Belt and many areas of Kansas, Missouri, and Nebraska are experiencing extreme drought. New research is summarized in this article on the impact of extreme heat and the profitability of Kansas farms.

Drought and heat stress impacts on soybeans in Kansas
Over the last week, impressive heat has taken hold of Kansas with absolutely no precipitation statewide. Dryland soybean fields are experiencing significant heat and drought stress. This article covers important information related to this stress, including the yield impacts and the use of failed soybeans as a forage.

A hot day for the record books in Kansas - August 19, 2023
Less than a month after a late July heat wave brought the hottest temperatures in years to parts of Kansas, another heat wave arrived on Saturday, August 19. This event brought even hotter temperatures to Kansas. This article looks at temperatures recorded at Mesonet stations across the state.
