Review of herbicide label requirements: Dicamba
This article is the first in a series reviewing unique or updated label requirements for key herbicides. Certain dicamba products were approved for post-emergence control of weeds in Xtend Soybean in 2017. The labels for these products include some additional requirements intended to reduce the potential for non-target injury caused by herbicide drift.
Review of herbicide label requirements: Paraquat
This article is the second in a series reviewing unique or updated label requirements for key herbicides. Paraquat is the active ingredient in the herbicide Gramaxone SL 2.0 and others. When handled carefully, paraquat is an effective weed management tool that would be difficult to replace in terms of effectiveness on hard-to-control species like pigweeds.
Review of herbicide label requirements: Enlist One and Enlist Duo
This is the third article in the series reviewing unique or updated label requirements for key agronomic herbicides. Keep in mind that instructions printed on the herbicide label supersede this information. Some of the unique label requirements when using Enlist One or Enlist Duo are discussed in this article from Dr. Sarah Lancaster.
Update on new herbicides for Kansas crops in 2020
Herbicides that have gained approval for use in agronomic crops in 2020 are discussed in this article, as well as some products that anticipate approval for 2020. Remember to always read and follow label directions.
Herbicide carryover considerations when re-cropping damaged wheat
Growers who decide to terminate their wheat crop because of poor stands or weather-related damage need to consider the persistence of herbicides applied to the wheat. Many wheat herbicides have fairly long crop rotation restrictions.
Considerations for applications of over-the-top dicamba formulations
It is that time of year again for post-emergent applications of Engenia, Fexapan, and Xtendimax on dicamba-resistant soybeans. In light of the recent court ruling, it is vital that application restrictions are followed closely to prevent non-target dicamba injury to conventional, Enlist, and Liberty Link soybeans.
Interim decision announced regarding atrazine registration review
Atrazine is a key herbicide for corn and sorghum production and fallow systems. An interim decision has been recently been released in response to a routine registration review. Read more about how this may affect Kansas farmers in this article.
EPA approves labels for over-the-top dicamba application
On October 27, 2020, the EPA issued approval for three labels for over-the-top dicamba application. The labels will be effective until 2025. More details are included in this article.
UPDATED - EPA approves labels for over-the top dicamba application
The article has been updated slightly from the original version published on October 30. Stay up -to-date on the recent EPA ruling concerning certain over-the-top dicamba products.
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.

New Enlist One and Enlist Duo herbicide labels approved
On January 11, the EPA renewed labels for Enlist One and Enlist Duo for seven years. These are the only 2,4-D formulations approved for over-the-top herbicide application to Enlist E3 soybean and Enlist cotton. The labels come with some additional restrictions compared to the previous labels.
Paraquat: What you need to know for use in 2022
Paraquat is a restricted use herbicide that was first commercialized in the 1960s and is one of the most widely applied herbicides in the United States. This article discusses recent changes made by the EPA in 2021 regarding the proper use of this herbicide.
Prohibition for Enlist One and Enlist Duo lifted for Kansas
Enlist One and Enlist Duo amended supplemental labels were approved on March 29 to allow use in 10 counties in Kansas (Chautauqua, Cherokee, Cowley, Elk, Greenwood, Labette, Montgomery, Neosho, Wilson, and Woodson)
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.

EPA seeking public comment on atrazine re-registration review decision
The Environmental Protection Agency has requested public comment on the proposed additional mitigations to reduce potential exposure and risk to aquatic communities from atrazine via runoff from agricultural uses in field corn, sweet corn, sorghum, and sugarcane. Details on how to submit comments are outlined in this article.
Check herbicide labels before using soybeans for livestock feed
Drought conditions throughout Kansas are forcing farmers to consider harvesting soybeans for forage instead of grain. Many factors should be considered when making this decision. Herbicide applications made during the growing season are one thing to consider. Many herbicide labels restrict the use of soybeans as a forage.
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.

Cut-off dates approaching for XtendiMax, Engenia, and Tavium applications
Farmers planning to apply XtendiMax, Engenia, or Tavium to their dicamba-resistant soybeans 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.
Unmanned Aerial Vehicle Pesticide Applications - What You Need to Know
There is a good deal of interest in using drones, also called unmanned aerial vehicles (UAVs) for the application of pesticides. If you are an applicator considering using a drone for applications, here is some basic information regarding licenses that you need to know before applying any pesticides.
Check herbicide labels before using soybeans for livestock feed
Drought conditions and extreme heat throughout Kansas are forcing farmers to consider harvesting soybeans for forage. The herbicide label is the law, and many herbicide labels do restrict the use of soybeans as a forage. It is important to know the waiting period between the application of a given herbicide and the grazing or harvesting of the soybeans for use as a forage.
Planting winter canola? Be aware of rotation restrictions with herbicides
Recent developments associated with market opportunities for winter canola may lead to increased planting in the fall of 2023 and beyond. When making seeding plans, be sure to consider the herbicides used this summer and those planned for the fall.
Fall herbicide applications - Atrazine label updates
Fall or early spring herbicide applications are a great proactive weed management strategy to ensure fields “start clean” at planting. Atrazine has historically been an important part of these programs. However, recent changes in atrazine labels mean that it cannot be used in some fall-applied scenarios. Learn more in this article.
