Corn earworms (Helicoverpa zea) are a species of moth whose larvae feed on a variety of crops in the Midwestern United States. The larvae mainly affect sweet corn and hybrid dent seed corn but also feed on field corn, tomatoes, peppers, lettuce, and snap beans.
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.
Published: Sept. 20, 2024 Cutting alfalfa when the weather is good can be tempting, but late fall cuttings could be damaging to long term alfalfa productivity and stand persistence. Why it might be bad to cut now As a perennial crop, one must manage alfalfa with not just this year but the next year in […]

In this video, Chris Clark and Jordan Kampa, outreach specialists for the UW-Madison Extension Nutrient & Pest Management program head to the field to talk about managing potassium in crops and the publication they co-authored on the Potassium Cycle, available now from the NPM program.
This publication is an overview of essential plant nutrients and the ways they interact with one another. Farmers and agronomists can use this guide as a tool in conjunction with a good soil testing program to help diagnose agronomic problems and consider their nutrient management strategy.
This comprehensive resource provides a visual overview of the potassium (K) cycle and breaks down the crucial role K plays in soils and crop growth to help you optimize your crop yield.
Many factors affect crop yield; only one of them is fertilizer. The six factors listed here have a strong relationship with consistently better-yielding areas of a farm field.
We’re starting to see some foliar diseases come into corn in WI, which may affect harvest timing and management. We’re not overly concerned; however, the time is right to be proactive and scout, scout, scout!
