Control annual weeds with fall-applied herbicides ahead of corn and sorghum
Now that row crop harvest is underway and fall moisture has been received, it is time to start planning fall herbicide applications to control winter annual broadleaf weeds and grasses ahead of grain sorghum or corn.
Kansas weeds: Know your mustard species
Several mustard species are found in Kansas fields, including tansy mustard, flixweed, bushy wallflower, field pennycress, and blue mustard. Can you ID these different species in the field? Learn about the identifying features of each one in this article.
Cover crop termination considerations
Now is the time to begin considering how to terminate winter cover crops in preparation for summer crops. Some cover crop species, such as oilseed radish or fall-planted oats, are likely to be killed by freezing over the winter. But, many cover crops will need to be terminated by mechanical or chemical methods in the spring.
Control options for buckbrush, roughleaf dogwood, and smooth sumac
Three common brush species native to Kansas are buckbrush, roughleaf dogwood, and smooth sumac. What are the best options for control of the brush species?
Kansas weed survey - Reminder to participate before August 31
Herbicide-resistant weeds are threatening the profitability and long-term sustainability of Kansas cropping systems. We are seeking input on this issue from Kansas farmers and agriculture professionals.
Kansas weed survey - Reminder to participate before August 31
Please consider completing a short survey on herbicide resistant weed control. The survey will close at the end of August. Information collected will help develop innovative, cost-effective and integrated weed management practices for Kansas farmers.
Weed management practices: Fall scouting for weeds
Weeds that escape control by in-season management practices can cause several problems at harvest and in future growing seasons.

Cover crop termination considerations
Now is the time to begin considering how to terminate winter cover crops in preparation for summer crops. While some species will be killed due to freezing over the winter, others will need to be terminated by mechanical or chemical methods.
Weed management practices: Fall scouting for weeds
Weeds that escape control by in-season management practices can cause several problems, including the possibility of reduced harvest efficiency and crop yield. Scouting for weeds at harvest is an important practice for planning future weed management.

Musk thistle control in the fall
Musk thistle is one of 12 noxious weeds in Kansas infesting nearly 500,000 acres. Control efforts should be aimed at reducing or eliminating new populations and established stands should be managed with any accepted control method. Fall is an excellent time to treat musk thistle since they are in the rosette stage of growth.
Early-season weed control in cotton
Early-season weed control is especially important in cotton because can be slow to canopy relative to other crops grown in Kansas, and therefore less competitive early in the growing season. Tillage is often used for early-season weed control; however, most Kansas cotton acreage is in conservation tillage systems, so effective herbicides are needed before planting.

Frontier District to host meeting on increasing row crop yields with weed and fungus control
The Frontier Extension District will host a meeting on increasing row crop yields with weed and fungus control at 6:00 p.m. on Feb. 22 in Overbrook. Learn about corn and soybean weed management, tar spot of corn, and Sudden Death Syndrome in soybeans.
Management options for control of field bindweed
Last week's eUpdate featured an article on field bindweed focusing on its ecology, growth characteristics, and identification methods. This week, the focus is on developing effective long-term control strategies for this troublesome weed that impacts Kansas farmers. A good control program will include cultivation, herbicide use, and competitive crops.
Controlling weeds after wheat harvest
The 2024 wheat harvest is well underway, so it is time to think about weed control in wheat stubble. Delaying control can result in lost soil moisture that could be used for crop production and weed seed production, which will cause difficulties in the future. There are two priorities: controlling already emerged weeds and preventing later flushes.
Palmer amaranth control in grain sorghum
When the aggressive nature of Palmer amaranth is combined with the limited post-emergence herbicide options in grain sorghum, problems often arise even when an adequate preemergence herbicide program is used. This article covers post-emergence herbicide options for Palmer amaranth control in grain sorghum.
World of Weeds - Purple threeawn
Purple threeawn is a warm-season perennial grass native to Kansas and the Great Plains that can be a challenging weed in fields under long-term no-till management. This species may be found invading fields along with tumble windmillgrass and tumblegrass - other problematic native perennial grasses. It is rarely consumed by animals and is an indicator of overgrazing on rangelands.
World of Weeds: Snow-on-the-mountain
It may still be summer in Kansas, but the newest World of Weeds feature is all about snow-on-the-mountain. This plant's showy, white foliage is very noticeable in late summer, and you may see it right now on roadsides and in pastures. Learn more about this weed, which can be toxic to humans and cattle.
