Stripe Rust Observed in Madison County Wheat

Retired commercial agriculture Extension educator Robert Bellm observed stripe rust yesterday in several wheat fields in Madison County ( Figure ). Rust pathogens are obligate parasites, meaning that they need a living host in order to survive. Wind and rain systems from further south bring spores to our area. This is why rust sightings in states to the South and in S...

Symptoms and signs of Fusarium head blight (scab) on wheat

Although wheat is typically grown primarily in southern Illinois, where producers are then able plant double crop soybeans, some wheat is also produced throughout the rest of the state. At the Northwestern Illinois Agricultural Research and Demonstration Center (NWIARDC), winter wheat has been included in Dr. Emerson Nafziger long-term tillage and rotation trial since 1996 and more recently has...

What happens 1 to 2 weeks after 85 true armyworms land in my pheromone trap?

No this is not a trick question; let me explain. What are true armyworms ? True armyworms are insect pests of grasses and crops such as corn and small grains. Many of the Bt-traited corn hybrids express proteins that provide protection against the true armyworm. However, not every Bt hybrid provides pr...

What is small plot research?

At the University of Illinois Research Centers we do small-plot research. This isn't research that takes place in the highly controlled environment of a laboratory or a test tube, but outdoors. A farm field is a diverse environment, with many abiotic factors (rocks and other inorganic soil components, soil nutrients, residual pesticides, temperature, humidity, wind, precipitation, etc.) and biotic...

Stripe rust observed at the NWIARDC

Dr. Carl Bradley, University of Illinois Plant Pathologist, observed stripe rust in some of his research plots at the NWIARDC this week (May 9th).  Symptoms and signs of disease were observed primarily on the variety called Kaskaskia. He observed the symptoms on several flag leaves and leaves below the flag leaf had moderate severity. These symptoms indicate that the pathogen has reache...

Time to scout your wheat

The Feekes wheat growth staging scale was developed to focus on important milestones in wheat development, particularly those that are important growth stages for scouting for insects, disease and weeds. See the blog article, Growth staging wheat , for more discussion about the Feekes sc...

Growth staging wheat

The Feekes wheat growth staging scale ( Figure ) was developed to focus on important milestones in wheat development, particularly those that are important for scouting for insects, disease and weeds. For diseases, scouting should typically begin at Feekes 8, when the flag leaf is first visible. The flag leaf is important to protect because this leaf provides the...
