WiscWeeds Program
Our Research and Extension Program (WiscWeeds) at the University of Wisconsin-Madison focuses on agroecologically-based approaches to address sustainable weed management in corn, soybeans and small grains in Wisconsin and beyond. Our program also focuses on weed management strategies that can help address herbicide resistance, protect water quality, enhance agroecosystems services and increase food security.

Planting winter wheat after soybean harvest? Check this blog post for information on winter wheat rotational restrictions following commonly used soybean herbicides.
Check the results and field images of 22 corn and soybean herbicide evaluation research trials conducted by the Wisconsin Cropping Systems Weed Science Program during the 2021 growing season.
Check the results of the 2021 WiscWeeds study evaluating multiple two pass herbicide programs for weed control in conventional corn.
Over the last two growing seasons (2020 and 2021), weather and soil conditions across southern Wisconsin were favorable for early soybean planting. Herein we attempt to address some of the questions we have been receiving regarding PRE-emergence herbicide selection for early planted soybeans.
We invite Wisconsin farmers and agronomists to collect waterhemp seeds this fall from their row crop production fields and submit them to UW-Madison for herbicide resistance screenings.

Projects
WiscWeeds Research Coalition - Ongoing Projects:
Given the widespread occurrence of herbicide-resistant weeds across Wisconsin Cropping Systems, the shortage of novel herbicide sites of action, and the socioeconomic and environmental challenges herbicide-resistant weeds bring to farming operations and communities, it’s time for our industry to come together and work towards a similar goal: to promote and hopefully achieve effective and sustainable weed control in crop production systems.
The objective of the WiscWeeds Research Coalition is to bring together Researchers, Educators, Policy Makers, Industry, Consultants, Service Providers, and Growers to work towards preventing the spread, reducing the selection for, and to increase the adoption of integrated management strategies to combat herbicide-resistant weed species. Through the WiscWeeds Research Coalition we expect to develop a strong relationship amongst key stakeholders allowing for effective exchange of materials, practical knowledge and research-based recommendations.

Rodrigo Werle is an Assistant Professor and Extension Cropping Systems Weed Scientist in the Agronomy Department at UW-Madison. His research and extension program (WiscWeeds) focuses on agroecologically-based approaches to address sustainable weed management in corn, soybeans and small grains in Wisconsin and beyond. The program also focuses on weed management strategies that can help address herbicide resistance, protect water quality, enhance agroecosystems services and increase food security.
Rodrigo was born in a small farming community of Dutch immigrants in the state of São Paulo, in southeastern Brazil. His early passion for Agriculture led him to study Agronomy in Brazil and Weed Science at Nebraska, which then brought him and his family to beautiful Wisconsin in 2018.
