Try togetherness: Study promotes cooperative weed management to curb herbicide resistance

The following article was written by Lauren Quinn, media specialist in the College of Agricultural, Consumer and Environmental Sciences at the University of Illinois.  The article describes recently publiched research, lead by Dr. Adam Davis, a research ecologist with USDA-ARS and adjunct professor in the Department of Crop Sciences, that examined cooperative weed management as a tool used against the challenges of herbicide-resistant waterhemp. … Read more

Residual Soybean Herbicides Applied Postemergence

Soil-residual herbicides are important components of integrated weed management programs.  Reducing the number of weeds exposed to foliar-applied herbicides helps reduce the selection intensity for weeds resistant to foliar-applied herbicides.  Residual herbicides applied with postemergence soybean herbicides also can reduce the need for a second postemergence application. … Read more

Soybean Cyst Nematode: Race Shifts and Grass Cover Crops as a Potential Alternative Control

Authors: Talon Becker and Nathan Kleczewski

Among the various soybean pests, Heterodera glycines Ichinohe, known by most as soybean cyst nematode (SCN), continues to be a persistent cause of yield loss for soybean producers1.  … Read more

Seedling Diseases in Soybeans – Time to Scout!

Now is the time that seedling diseases of soybeans will start to be apparent.  Indeed, we have started to see more images of soybeans that may have symptoms of seedling disease.  However, it is important to understand that seedling diseases are complex, and a simple picture often is not sufficient to adequately diagnose the issue. … Read more

Western Corn Rootworm: Adult Sampling and Economic Thresholds

Authors: Nick Seiter, Joe Spencer, and Kelly Estes

Based on degree day accumulations, western corn rootworm egg hatch should be underway in much of Illinois (roughly south of Peoria as of May 29; you can view your specific location using the degree day calculator here: https://www.isws.illinois.edu/warm/pestdata/sqlchoose1.asp).… Read more

Corn Growth Stage and Postemergence Herbicides

The labels of most postemergence corn herbicides allow applications at various crop growth stages, but almost all product labels indicate a maximum growth stage beyond which broadcast applications should not be made, and a few even a state minimum growth stage before which applications should not be made. … Read more

New Crop Protection Network Publication on Proper Fungicide Use for Fusarium Head Blight Now Available

The Crop Protection Network is a free, online resource for producers and those in the agronomic community interested in diseases of field crops and their management.  Recently, CPN started adding resources to the site to include diseases of small grains such as wheat. … Read more

Diagnosing disease related issues in the field

Well, it is that time of year where we start to see issues developing in the field.  Questions such as, “What happened?”  and  “Why me?” will become more common.  The key to managing diseases is proper diagnosis, and this starts in the field. … Read more

A fast start for the 2018 crop

We worried our way through the cool month of April, with 32 percent of corn and only 7 percent of soybean acres planted by April 29, and nothing emerged. During the first two weeks of May, the weather was warmer and drier than normal, and adding together corn and soybeans, Illinois farmers planted more than a million acres for each of the 10.3 “days suitable for fieldwork” between April 29 and May 13.… Read more
