How Extensive Is Resistance to Group 15 Herbicides in Illinois Waterhemp Populations?
Waterhemp populations from soybean fields across Illinois are being collected and screened to better understand the level of resistance to Group 15 herbicides. Results [...]
Which Preemergence Herbicides Are More Likely To Cause Crop Injury When Soybeans Are Planted Early?
Planting soybeans early often means cold, wet soil conditions that can delay seed germination and prolong plant emergence. These conditions can reduce the plant’s [...]
Which Practices Help Improve Soil Health and Water Quality While Also Giving Me the Ability To Take Advantage of Ecosystem Markets Like Carbon Credit Programs?
This project is collecting soil health, water quality and climate footprint metrics across the state’s growing regions and cropping systems (soy-corn, double-crop wheat-soy with [...]
Which Insect Pests and at What Threshold Levels Warrant an Insecticide Application or an Insecticide Seed Treatment in Soybeans?
This multi-year project aims to identify insect pests responsible for reducing soybean yield and grain quality and which control mechanisms, including seed treatment and [...]
Which Wheat Varieties Offer Better Spring Freeze Tolerance and Allow Earlier Harvesting for Timely Double-Crop Soybean Planting To Maximize Yield Potential?
Double cropping soybeans after winter wheat is an attractive approach to enhancing profitability in Midwest crop rotations and improving soil health. This project is [...]
What Is the Ideal Planting Window To Establish Cover Crops and Obtain Optimum Crop Growth and Yield of Rotational Crops?
This project is comparing 1) different cereal rye seeding dates and rates before soybean, and 2) different planting dates of two clover species after [...]
How Can I Offset Some of the Potential Challenges When Planting Soybeans Into Heavy Corn Residue?
To help more farmers feel confident implementing conservation tillage systems, this project is investigating the interactions across soil types, starter fertilizer, tillage systems and [...]
How this research benefits the farmer
Understanding the presence of Group 15-resistant waterhemp will give farmers, their advisors and Extension the ability to refine integrated weed management recommendations to help [...]
Why this research is important
Waterhemp populations in Illinois have evolved resistance to herbicides from more site-of-action-groups than any other weed species. The confirmation of resistance to Group 15 [...]
Trial locations
Waterhemp seeds will be collected from at least 100 locations across the state
