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.
The new 2020 K-State Weed Control Guide is now available online! Don't miss this valuable resource brought to you by K-State Research and Extension. Hard copies will be available soon.
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.
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.
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.
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.
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.
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?
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.
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.
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.
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.
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.
Be mindful of the many ways that weeds can spread from field to field, including hitching a ride on harvest equipment. Learn what steps can be taken to minimize spreading weed seeds during harvest activities.
There is still time to participate in a short survey concerning your soybean planting intentions for the 2021 season. This survey will help guide winter extension programming and is completely anonymous.
