The increased water demand led by greater fall biomass production was, unfortunately, met with below average precipitation during the late fall and winter – especially in western Kansas, leading the crop to experience early signs of drought stress in that portion of the state. While the crop in central Kansas is still mostly not undergoing severe drought stress, the recent increase in biomass as the crop goes into reproductive development will be accompanied by an increase in crop water demand; thus, more precipitation will be needed shortly to avoid yield losses due to drought.
Injury symptoms from freeze damage to wheat: what to look for?
The recent cold temperatures experienced during 31 March – 14 April 2022 were enough to cause freeze damage to winter wheat in parts of Kansas. The actual freeze damage will be region-specific depending on crop growth stage and minimum temperatures (some regions had a worst combination of temperatures and crop growth stage) and, within a region, field specific owing to many individual aspects such as crop density, residue level, etc.
Brown Wheat Mite Outbreaks in Western Kansas
Reports of brown wheat mite outbreaks have come in from southwest and northwest Kansas in the last two weeks. Brown wheat mite is a sporadic pest of wheat in western Kansas but can also become problematic in eastern Kansas during dry years. Typically, continuous wheat faces a higher risk of damage from this pest and injury can be confused with drought stress.
Wheat disease update: April 21, 2022
With dry conditions throughout Kansas, disease pressure has been below average in most scouted locations. At the time of publication of this article, there have been no reports of either stripe rust or leaf rust in Kansas. Additionally, there have been reports of low rust pressure in both Oklahoma and Texas. Dry conditions in the region may be suppressing disease development.
Wheat Disease Update: May 4th 2022
Your wheat disease update as of May 4, 2022, is here! As wheat moves into the flowering stage of growth in southeast Kansas and into heading and boot stages of growth in central Kansas, there are a few diseases that are on the mind of many producers and advisors, including: rusts (stripe and leaf); Fusarium head blight (scab); and wheat streak mosaic virus (and related viruses). In this article you’ll learn about the current outlook for these diseases, and the potential need for management.
Wheat Tour Schedule 2022
The Department of Agronomy and K-State Research and Extension will host several winter wheat variety plot tours in different regions of the state, starting May 11, 2022. Make plans to attend a plot tour near you to see and learn about the newest available and upcoming wheat varieties, their agronomics, and disease reactions.
Checking Wheat Heads for Pollination Problems
Many environmental conditions can cause pollination problems in wheat, such as freeze damage, drought, or heat stress. This year, the most concerning factor as it relates to a potential for unsuccessful pollination is heat stress, in particular that experienced during May 9-12
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.
2022 Kansas Wheat Crop Conditions: a report following the Wheat Quality Tour
The 2022 Wheat Quality Tour took place May 16 - 19, 2022. About 85 people actively scouted hundreds of Kansas wheat fields in 21 groups spread across six routes. The Kansas wheat crop is currently facing many challenges. Consequently, the overall 2022 production estimate for Kansas resulting from the tour was 261 million bushels of wheat, compared to 364 million bushels estimated by the tour in 2021.
Possible causes for white heads in wheat
White heads have been appearing in many wheat fields around Kansas. Sometimes the white heads are just single tillers scattered throughout part or all of a field, and sometimes they occur in small-to-large patches. Heads might be completely white starting from the stem, or may just have a few spikelets showing the discoloration. There are many causes of white heads. This article reviews some of the most common causes and their diagnosis.
Considerations when harvesting short wheat
In many areas of Kansas, prolonged drought has resulted in short wheat and thin stands. Harvesting wheat in these situations can be a challenge. Special attention needs to be given to cutting height, machine adjustments, and operator control. In short wheat, getting the heads into the combine with less straw will be a challenge.
Pre-harvest weed control in wheat
Making a herbicide application that will not directly influence crop yield is a difficult decision to make. Such is the case with pre-harvest weed control applications to wheat fields. However, pre-harvest applications may be beneficial, especially in wheat fields with short or thin stands or fields that were not treated earlier in the season. When broadleaf weeds grow rapidly at the end of the growing season, several potential concerns arise such as harvest difficulties, dockage problems, weed seed production, and soil water depletion.
Wheat Tour Schedule 2022
The Department of Agronomy and K-State Research and Extension will host several winter wheat variety plot tours in different regions of the state over the coming weeks. Make plans to attend a plot tour near you to see and learn about the newest available and upcoming wheat varieties, their agronomics, and disease reactions.
Considerations for weed control following wheat harvest
Post-harvest weed control in wheat stubble is very important to conserve critical soil moisture and prevent weeds from going to seed and adding to the weed seedbank. This year, it will be especially important to be ready to spray after wheat harvest because of less cover from shorter and thinner wheat than we have seen in the last few years in many areas. When thinking about weed control in wheat stubble, there are two priorities – controlling already emerged weeds and preventing later flushes.
Double cropping options after wheat
Double cropping after wheat harvest can be a high-risk venture. The available growing season is relatively short. Heat and/or dry conditions in July and August may cause problems with germination, emergence, seed set, or grain fill. Ample soil moisture this year can aid in establishing a successful crop after wheat harvest. Read more about herbicide carryover potential and management considerations for double cropping with soybeans, sorghum, sunflowers, summer annual forages, and corn.

The Department of Agronomy and K-State Research and Extension will host several more winter wheat variety plot tours this week. Make plans to attend a plot tour near you to see and learn about the newest available and upcoming wheat varieties, their agronomics, and disease reactions.
Managing late tillers in wheat
Rains during the past two weeks have resulted in a flush of late, green tillers in the wheat over much of Kansas. This can create a problem, especially for wheat that is approaching harvest maturity. A question that usually arises when this happens is: Should I wait to start harvesting until most of the green heads have matured, or just start harvesting anyway? This question is more relevant this year in south central Kansas, where the wheat is most advanced. In these cases, producers should not delay harvest because of the green tillers. These tillers probably won’t amount to more than 5% or so of the total amount of heads in the field, and won’t add much to the final yield anyway.
Effect of heat and drought during grain fill on wheat seed quality
Wheat that has been stressed by drought and extreme heat can have seed quality concerns. Drought conditions were prolonged in many areas of Kansas through most of the winter and spring in 2022, causing stress to plants through early grain filling stages. In addition, extreme heat occurred during the four-day period of May 9-12, which coincided with boot, flowering, pollination, and early grain fill stages depending on the area within Kansas.
Accelerated Aging test on seed for emergence vigor
Beyond the standard germination test, most professional seed testing labs offer an Accelerated Aging (AA) test that will test seed for anticipated emergence vigor. This test is very capable of identifying weak seed lots where there are issues with Fusarium head scab; heating in the bin; or smaller, development-stressed seed.
World of Weeds: Jointed goatgrass (Aegilops cylindrica)
This World of Weeds feature will discuss this weedy relative of wheat, also know as joint goat grass. Jointed goatgrass is a winter annual that germinates roughly the same time as winter wheat and the rate of development of the two species is similar throughout the growing season. It is native to southern Europe and is thought to have been introduced in Kansas during the 1900s as a contaminant in imported wheat. It can be found in a variety of habitats, including roadsides, rights of ways, and fields throughout much on the United States, including all of Kansas.
Wheat streak mosaic virus: Problematic in central Kansas for the second year in a row
For the second year in a row, wheat streak mosaic virus was problematic in wheat in the central corridor of Kansas. One of the best preventative measures for wheat streak is the control of volunteer wheat early and often after harvest. Volunteer wheat should be terminated at least two weeks prior to planting.
