January Webinar: Crop Advisors’ Perspectives on Pesticide Resistance Management

Katherine DentzmanJoin Dr. Katherine Dentzman, Assistant Professor of Rural Sociology at Iowa State University, as she shares insights about how crop advisors influence the use of pest management practices among farmers. Dentzman analyzed a national survey of certified crop advisors to better understand crop advisor perspectives on the issue of pesticide resistance, what management options they recommend, and any barriers they may face to assisting farmers in dealing with resistance issues.

Register now to receive the webinar link. This webinar will be held on Wednesday, January 17 at 1:30 pm ET (12:30 pm CT). “Pests and Progress” webinars are free, and more details are on the North Central IPM Center website.

Great Lakes Urban Agriculture Working Group Pest Cards

The Great Lakes Urban Agriculture Working Group distributed a survey to learn which urban pests are causing problems and where gaps exist in management knowledge. In response to survey results, fourteen pest cards have been created and shared, featuring topics from groundhogs, deer and rabbits to squash bugs and aphids. Check out the full list of pest cards on the Purdue University’s Urban Agriculture page. Each of these fact sheets includes general information about the problem pest along with management recommendations. Both English and Spanish versions are available.

War Against Weeds Podcasts

The War Against Weeds Podcast Working Group began in 2021. Since then, over 100 podcasts have been produced with topics ranging from harvest weed seed control to cover crops and use of electricity for weed control. Recent episodes include herbicide modes of action, weed management perspectives from Europe and targeted herbicide applications.

Check out the full list of episodes on the War Against Weed website.

US Environmental Protection Agency Updates

EPA Seeks Public Comment on Petition for Rulemaking to Require Efficacy Data for Systemic Insecticides

Do you use neonicotinoids and other systemic insecticides? Now is your chance to share feedback about how you use them and why. The U.S. Environmental Protection Agency (EPA) is reviewing rules for neonicotinoid and systemic insecticides to determine whether the benefits of these products outweigh the environmental costs.
Be sure to share your comments by January 23, 2024. To view the petition or submit a comment, go to www.regulations.gov and search for docket ID EPA-HQ-OPP-2023-0428.

EPA Posts Final Endangered Species Act Biological Opinion for Enlist Herbicide Products

The U.S. Environmental Protection Agency (EPA) is working to determine whether Enlist herbicides pose a threat to species listed under the Endangered Species Act. The EPA has been working with the U.S. Fish & Wildlife Service to prepare the final Biological Opinion, which is now available. In general, Enlist products used in accordance with the label are not likely to jeopardize listed species or adversely modify their critical habitats, but there are areas where additional application rules may apply due to proximity to critical habitat. Any areas where extra rules apply can be found on the Agency’s Bulletins Live! Two system, along with the mitigation options. The EPA intends to have label revisions approved in advance of the next growing season.

The full Enlist Biological Opinion can be accessed at docket ID EPA-HQ-OPP-2021-0957 at regulations.gov.

EPA Releases Draft Biological Evaluation of 11 Rodenticides’ Effects on Endangered Species

The U.S. Environmental Protection Agency (EPA) has created a draft Biological Evaluation to assess whether 11 rodenticides affect species listed under the Endangered Species Act. While most listed species will not be affected (88%), there are potential effects for others.
Based on these findings, updates will be made to rodenticide rules. For example, application of rodenticides directly to water will not be allowed. Since there is not much risk of drift of rodenticides, restrictions for applying them near critical habitats will be revisited.
The 11 rodenticides evaluated in the draft Biological Evaluation include chlorophacinone, diphacinone and its sodium salt, warfarin and its sodium salt, brodifacoum, bromadiolone, difenacoum, difethialone, bromethalin, cholecalciferol, strychnine, and zinc phosphide.

Drones for Spraying Pesticides

Drone spraying crops

Can drones be used to direct spray applications exactly where they are needed? Check out this “Field Crops Virtual Breakfast” webinar featuring Dr. Erdal Ozkan, professor in the Department of Food, Agriculture and Biological Engineering at The Ohio State University to learn about the potential for combining drones and agriculture. A fact sheet covering similar topics is available as well.

Preparing for Next Season

Improving Wine Grapes for American Growers and Winemakers

Recent research on grape varieties helps growers make decisions about which grape variety to plant. Frost tolerant and cold-hardy varieties were developed and trialed. Grape varieties were also tested for levels of acids and tannins as well as resilience against virus and diseases. Grape trials were planted at multiple universities in the Midwest and Northeast regions; read more about the studies and conclusions in this two-page summary.

Mungbeans: Potential for Crop Diversification in Kansas

When looking for an option for rotating crops in Kansas, consider mungbeans. Mungbeans are increasing in popularity and provide nutritious protein-rich seeds. They fix nitrogen in the soil just like soybeans. Read more about growing mungbeans in Kansas or check out this video about breeding mungbeans in the Midwest.

2024 Crop Hour Webinars

Details for the spring 2024 Crop Hour webinars are available from South Dakota State University Extension. Crop hour webinars will be held on Tuesdays, Wednesdays, and Thursdays from January 9 to March 7, 2024, at 11:00 a.m. ET (10:00 a.m. CT).

December Weed of the Month: Saltcedar

The Minnesota Department of Agriculture has added saltcedar to Minnesota’s noxious weed list. While saltcedar has been planted as a windbreak or for erosion prevention, its high seed production and quick growth can help it take over natural spaces. The leaves of saltcedar are also covered in salt so when the shrub drops its leaves, the surrounding soil becomes more salty. This also decreases germination of other plant species.

What’s on Your Seed: Soybean Seed Treatment List (WI)

While soybean seed treatments were originally introduced to help protect against disease, these treatments have become much more complex. Seed treatments are available for a range of crops along with ingredients to protect against disease, insects and nematodes. Check out this list for a visual summary of treatment options.

K-State 2024 Chemical Weed Control Guide is Now Available Online

A comprehensive guide for herbicide use is available from Kansas State University. Topics include everything from herbicide application to herbicide recommendations for specific crops and specific challenges (such as noxious weeds or trees on rangeland).
