The Herbicide Mitigation Strategy is one of the first phases of the Environmental Protection Agency’s (EPA) work plan to achieve compliance with the Endangered Species Act (ESA) and will set the tone for subsequent changes in the coming years. Moving forward, the herbicide strategy will be applied to all new herbicide active ingredient registrations and be considered during the herbicide registration review process. Outlined below are the key changes to the label and mitigation practice resources.
Do you want to get a head start on managing next year’s insect pests? Focus on managing your crop residue. Removing or tilling in crop residue this fall could make a big impact towards pest management. Read for pest-specific strategies on residue management as well as other cultural control options.
As more farmers have now grown up in the age of computers and software development, we are starting to see an increase in open-source projects related to agriculture. Open-source software (OSS) is a software product for which the code is freely available to the public to use or modify.
Dr. Tommy Butts, assistant professor of weed management at Purdue University, presents on the chemistry of herbicide applications.
Dr. Tommy Butts, assistant professor of weed management at Purdue University, covered conventional technology related to drift and weed control. Butts dug into the effects of spray volume, spray pressure, droplet size, and tip selection related to herbicide type.
Soybean aphids (Aphis glycines) are an invasive pest that can significantly stunt plant growth and yield. Soybean aphids feed on the sap of plants and leave behind a sticky residue.
European corn borers (Ostrinia nubilalis) are destructive corn pests in Wisconsin. Larvae feed on corn leaves and in developing tassels, stalks, and ear tips. European corn borer damage reduces grain quality, increases grain loss, and leads to problems at harvest.
Corn earworm (Helicoverpa zea) larvae feed on a variety of crops, mainly impacting sweet corn and hybrid dent seed corn. Larvae feed on the tips of corn ears, damaging kernels and contaminating the ears with frass.
In spots, too much water accumulated and led to drowned out spots and in some cases even entire fields. In spots, these areas were re-planted. In other areas, troublesome weeds like waterhemp are quickly escaping and will likely produce plenty of seed before a killing frost occurs.
As we pass the halfway point of the 2024 growing season, it’s important to remember that insect pests currently in fields may also affect 2025 crops. Many pests lay eggs that overwinter and can cause crop damage in the subsequent year. Corn rootworm is a key pest to watch.
Scouting is more important now than ever. Why? Well, a general rule of thumb is problems are best handled early. This applies to insect pests as the earlier you see an infestation, the easier it is to avoid economic damage. So, you might be wondering, what should I be watching for right now?
Western bean cutworm (Striacosta albicosta) is an economic pest in dry bean and corn production. Despite its name, western bean cutworm (WBCW) does not naturally feed on field soybeans. Larvae feed on corn ears, leading to yield loss and reduced grain quality.
