Wisconsin Field Crops Pathology Fungicide Test
and Disease Management Summary 2025

This report is a concise summary of pesticide related research trials conducted in 2025 under the
direction of the Wisconsin Field Crops Pathology program in the Department of Plant Pathology at the
University of Wisconsin-Madison.
Quantifying Nitrate Leaching from Agricultural Soils

Minimizing nitrogen (N) loss to groundwater is important for human health, the environment, and long-term farm profitability. Quantifying nitrate leaching – a primary pathway of nitrogen loss from agricultural fields – can help you understand the influence of different management practices on water quality, and identify options for reducing nitrate leaching.

Establishing alfalfa following wheat

Look out for herbicide carryover, volunteers in late summer seeding of alfalfa after wheat.
As we head toward the end of summer, it is closing in on time for a late summer establishment of alfalfa. Commonly in Wisconsin, this is done following a wheat crop in the spring. This can lead to a few challenges to consider: residual herbicide carryover and the effects of volunteer wheat on successful establishment.
Giant Ragweed Control- Research Summary

This publication–which was the result of six years (2018-2023) of giant ragweed driven research projects–was conducted by the WiscWeeds team at the Rock County Farm (Janesville, WI) and sponsored by commodity groups and crop protection industry. It will benefit those battling giant ragweed.
Waterhemp control in XTendFlex soybean without dicamba

The Wisconsin Cropping Systems Weed Science program has conducted several research trials investigating postemergence (POST) weed control in XtendFlex soybean systems (dicamba-, glufosinate-, and glyphosate-resistant soybean) without OTT applications of dicamba. Follow link for the full article:
2023 Wisconsin Weed Science Research Report
The purpose of this report is to share the results of corn, soybean, and spring wheat herbicide evaluation research trials conducted by the Wisconsin Cropping Systems Weed Science (WiscWeeds) Program during the 2023 growing season.
2024 Cereal Rye Cover Crop Research Report
“The adoption of cereal rye (Secale cereale) cover crop has triggered the interest of farmers as an additional tool for pigweed
(waterhemp [Amaranthus tuberculatus] and Palmer amaranth [A. palmeri]) management in soybean production systems. Along
with interest in this practice, there have been many questions about how cereal rye can impact other weed management
practices, such as the fate of PRE-emergence (PRE) herbicides in the soil when applied over high cereal rye biomass.” Follow link below to view this multi-state field study.

Sam Bibby serves as Regional Crops Educator, covering La Crosse, Vernon, and Crawford counties. Sam works to address the specific needs of producers and community members related to crop production. Outreach efforts will aim to form a bridge between university lead research and on farm practices.
He attended the University of Wisconsin-Platteville where he earned his undergraduate degree in soil and crop science in 2019. He then attended North Dakota State University and earned his master’s degree in plant science. Sam’s masters research was titled “Corn-Alfalfa Intercropping with Different Row Spacings” and was focused on developing a more profitable way for producers in the Northern Great Plains to establish alfalfa. Most recently, Sam worked for the NDSU Forages and Industrial Crops Program as the Research Specialist and was responsible for designing, managing, and analyzing field trials related to forage and industrial crop production.
Sam’s primary interests lie in conservation, farm technology, intensive crop management, forages, and alternative crops. Sam hopes his background in research and day-to-day farm operations will help him deliver tangible, data driven solutions to growers.
