2018 Crop Management Conferences Registration Open

Registration is open for the 2018 Crop Management Conferences. These regional conferences provide a forum for discussion and interaction between participants and university researchers. We are looking forward to introducing new specialists from the University of Illinois, and have adjoining state specialists joining us at Mt.… Read more

Precautions for Dicamba Use in Xtend Soybeans

The extension weed science programs at The Ohio State University, Purdue University, and the University of Illinois recently collaborated to produce suggestions and precautions for use of dicamba in dicamba-resistant soybean.  The United States Environmental Protection Agency issued amendments to the Xtendimax, Engenia, and FeXapan labels last October, and this new extension weed science publication offers additional suggestions to help further reduce off-target dicamba movement. … Read more

Label Changes for XtendiMax, Engenia, and FeXapan

On October 13, the United States Environmental Agency (EPA) issued several amendments to the XtendiMax, Engenia, and FeXapan labels that will impact all purchases and applications of these products in 2018 and beyond.  These amendments can be summarized as:

1) XtendiMax, Engenia, and FeXapan are now restricted use products (RUP), permitting only certified applicators to purchase and/or apply these products.… Read more

Timing Fall Nitrogen

The substantial rain that fell over central and northern Illinois between October 5 and 15 mostly soaked into the soil that was dried out by crop water use, and harvest has moved back to full speed in most areas.… Read more

Weed Seed Destructor Field Demonstration Reminder

Here is a great opportunity to see a novel weed management tool!  Dr. Adam Davis, USDA/ARS weed ecologist at the University of Illinois, will host a field demonstration of the Harrington Seed Destructor (HSD) on October 12. … Read more

Using the N rate calculator

A group of people who work on nitrogen fertilizer met in 2004 to talk about an alternative to the yield-goal-based N recommendation system that had been in widespread use for some three decades. The main concern with the yield-goal-based system was that, as corn yields increased over time, N rate trials were showing that the amount of fertilizer N needed to maximize yields was not going up as fast as yields.… Read more

Issues as Harvest Approaches

It is looking like at least some harvest surprises may be positive after an up-and-down 2017 season in Illinois. The September 1 yield predictions released by the USDA this week are for Illinois corn yield to average 189 bushels per acre, up a bushel from the August 1 estimate.… Read more

New Grain Phosphorus and Potassium Numbers

Corn and soybean take up relatively large amounts of phosphorus (P) and potassium (K), and much of this P and K ends up in the grain that is taken off the field during harvest. In order to keep soil nutrient levels from dropping over time, the amounts removed need to be replaced by applying fertilizer or manure.… Read more

Increased Insect Densities Reflected in Annual Corn and Soybean Survey

 

Thirty-six counties representing the nine crop reporting districts were surveyed at the end of July/beginning of August as part of our annual statewide corn and soybean survey. The surveys were performed by sampling five corn and five soybean fields per county.… Read more

The Dicamba Dilemma in Illinois: Facts and Speculations

Only a short time ago, many agricultural professionals were optimistic Illinois would somehow be “spared” the incidents of off-target damage caused by dicamba that continue to plague several states to our south.  The recent preponderance of evidence (observations made traveling the state, stories on social media, an increasing number of pesticide misuse complaints filed with the Illinois Department of Agriculture (IDOA), etc.), suggests otherwise. … Read more
