Herbicide applications and cold temperatures
Recent drops in temperature have prompted concerns about the effectiveness of herbicide applications made during cold weather. What are the risks when applying herbicides during cold weather?
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.

Herbicide application practices in Kansas
The K-State Weed Science Extension team is looking for your input! Herbicide application practices such as sprayer speed and spray volume influence weed control as well as whole-farm efficiency. Please consider filling out a short survey related to this topic.
Survey: Herbicide application practices in Kansas
If you did not get a chance to participate in a short survey about your herbicide application practices back in February, you have another chance! Help out the Extension Weed Science Team and fill out this short survey! Thank you!
Pre-harvest weed control in wheat
Herbicide applications that will not directly influence crop yield can be a tough choice to make. There are some indirect benefits to pre-harvest herbicide applications in wheat, especially in fields with a high weed density. Learn more about this management practice in this article.
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.
Cut-off dates for XtendiMax, Engenia, and Tavium applications
Don't forget that the 2021 labels for over-the-top applications of herbicides containing dicamba have cut-off dates. For soybeans, this cut-off is just around the corner. Applications to cotton have a few weeks longer. Read more in this short article from Sarah Lancaster.

Control woody plants on rangeland: Basal bark and cut-stump herbicide applications
Late summer and fall can be an excellent time to treat unwanted stands of woody plants. Scattered stands of individual trees should either be treated individually using the basal bark method or the cut stump treatment method.
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.
Cut-off dates approaching for XtendiMax, Engenia, and Tavium applications
Farmers planning to apply XtendiMax, Engenia, or Tavium to their dicamba-resistant soybean have about two weeks remaining to make those herbicide applications. These are the only dicamba-containing products labeled for over-the-top use in dicamba-resistant soybean and cotton. The last day these products can legally be applied to soybean is June 30. The cut-off date for cotton is July 30.

Review of restricted use pesticides and applicator licenses
As the 2023 field season gets into full swing, now is a good time for a refresher on restricted-use pesticides (RUPs) and pesticide applicator licenses. This article goes over the different categories of pesticides according to use and the importance of accurate record keeping.
Proper pesticide use: Why should an applicator care?
The label is the law - most pesticide applicators are familiar with that phrase. Yet, pesticides are sometimes used in ways that are inconsistent with product labels. Label directions are written to minimize risks for applicators, bystanders, and the environment. This article explains why applicators should prioritize reading and following pesticide labels.

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.
Pre-harvest weed control in wheat
A warm spring this year has resulted in rapidly maturing wheat. There have been some questions about spraying herbicides on wheat that has already headed. This article discusses herbicide options for wheat that serve as harvest aids. Pre-harvest applications may be beneficial this year to prevent harvest difficulties, dockage problems, weed seed production, and soil water depletion due to weeds.

Herbicide applications: Avoid a tank-mix mishap
Tank-mixing herbicides and other agrichemicals is necessary to increase weed control and use machine hours wisely. Unfortunately, the likelihood of physical incompatibility increases as the number of products added to a tank-mix increases. This article will briefly overview the principles of tank-mix order for herbicide applications.

Herbicide applications and high temperatures
Much warmer temperatures are forecast for the latter part of June across Kansas. If you are planning herbicide applications, there are some important considerations when applying these chemicals during periods of high temperatures.
Update on the registration of over-the-top dicamba products
As the 2024 growing season wraps up and growers start to think about seeding plans for 2025, questions are resurfacing about dicamba-resistant soybeans and cotton. In this article, learn more about what to consider when looking ahead to next year and the use of dicamba.

Mixing ammonium thiosulfate with herbicides: Considerations for spring applications
With spring burndown applications well underway, we've recently had some questions about mixing ammonium thiosulfate (ATS) with herbicides. This article discusses using ATS as a carrier and an ammonium sulfate (AMS) replacement as a water conditioner and adjuvant.

The role of water quality on effective herbicide applications
Understanding spray water quality is a crucial first step for successful herbicide applications. Water quality has a significant impact on herbicide efficacy. This article will focus on the effects of water quality on herbicide efficacy, particularly in postemergence applications.
Integrating spray drones into herbicide applications
Managing herbicide-resistant weeds and hard-to-reach areas like ditches and field edges remains a major challenge. Spray drone technology is quickly gaining ground as a flexible and efficient solution, especially when conditions make traditional equipment less practical.
