Control of mustards in wheat - Timely treatment is important

Too often producers do not notice mustard weeds in their wheat fields until the mustards start to bloom in the spring. As a result, producers often do not think about control until that time. Minimize yield loss by getting control of these weeds by late winter or very early spring.

Marestail in soybeans: Strategies for the best control

Controlling marestail in soybeans continues to be a big challenge for Kansas no-till producers. Application timing and weed size are critical factors for successful control of this weed that germinates in the fall or early spring.

Pay attention to growth stage for spring herbicide decisions on wheat

Producers should pay close attention to the growth stage of their wheat before making spring herbicide applications. Some herbicides must be applied after tillering, several must be applied before jointing, and others can be applied through boot stage.

Pre-emergence herbicides for corn

Applications of pre-emergence herbicides at or before corn planting are important to minimize yield losses to early-emerging weeds. Learn more about this weed management practice in this article.

Weed management considerations for flooded fields

Many fields across Kansas and neighboring states were covered by flood waters during portions of 2019. These fields may need special considerations when it comes to weed management.

Considerations for pre-emergence herbicides

Pre-emergence, soil-active herbicides applied around the time of planting are an important part of a good weed management program. However, variability in spring weather leads to concerns about both weed control and crop injury.

Pre-harvest weed control in wheat

Drought and late freezes have impacted wheat stands in many areas across Kansas this year. As a results, weeds are showing up and taking advantage of thin wheat stands. What are the best options for weed control at this point in the season?

New study evaluated different herbicide programs for Palmer amaranth control in post-harvest wheat stubble

A field study was recently conducted that evaluated the performance of various herbicide programs for Palmer amaranth control in post-harvest wheat stubble. Learn more about the results of this research in this article from Weed Scientist, Dr. Vipan Kumar.

Considerations for weed control following wheat harvest

Post-harvest weed control in wheat stubble is very important to conserve soil moisture and prevent weeds from going to seed and adding to the weed seedbank. Weeds are likely to be growing quickly, especially where there are thin stands.

Post-wheat harvest weed control in dryland cropping systems

Controlling weeds is key in order to maximize the benefits of stubble and no-till dryland cropping systems in western Kansas. Read more about the effects of weed control timing after wheat harvest in this article.

In-season Palmer amaranth control in grain sorghum

With adequate moisture and high temperatures, Palmer amaranth populations are rapidly growing and causing concern for some sorghum producers in western Kansas. What options to growers have at this point in the growing season? Read more in the article from weed scientist Dr. Vipan Kumar.

Control annual weeds with fall-applied herbicides ahead of corn and sorghum

With row crop harvest well underway, it is time to start planning fall herbicide applications. Herbicide applications in late October through November can improve control of difficult winter annual weeds.

Pre-plant herbicide applications for kochia control

Now is the time to finalize plans for kochia control. Recent research suggests that kochia can begin emerging in early February with most kochia emerging by early April. This article will be the first in a series discussing specific options for various cropping systems.
