Develop tools to detect Group 15 herbicide resistance in waterhemp before residual control visibly fails, helping farmers distinguish resistance from weather effects and make field specific herbicide decisions that protect early season weed control.

Identify how temperature and herbicide rate affect glufosinate performance on waterhemp to help farmers improve POST control, slow resistance development, and protect one of the last effective herbicide options for soybean production.

Waterhemp with nontarget-site resistance is one of the biggest weed challenges for Illinois farmers. Using an epidemiological approach with real field histories, this project will identify which management practices best slow resistance so farmers can protect herbicides, maintain yields, and manage waterhemp sustainably.

Detect red crown rot (RCR) hotspots with satellite imagery, evaluate commercial products, and study how those treatments influence the interaction between RCR and soybean cyst nematode to improve disease management in soybean fields.

Evaluate the effectiveness of PRE and POST herbicide programs, with and without cereal rye, for weed control in early-planted no-till soybeans to help farmers maintain yield and manage resistance under tight application windows.

Develop integrated weed management strategies that combine cover crops, herbicides, and tillage to control herbicide-resistant waterhemp, protect soybean yields, and support long-term sustainability.

Develop and test bioherbicides that specifically target palmer amaranth (pigweed) and waterhemp without harming soybeans, while creating a commercialization roadmap to provide farmers with a cost-effective, sustainable weed control option.

Assess how cover crops influence lesion nematode populations and their impact on soybean yield through field and greenhouse studies, while identifying and evaluating the pathogenicity of different lesion nematode species found in Illinois.
