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?
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.
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.
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!
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.
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.
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.
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.
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.
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.
