Insects require a certain amount of heat to develop from one stage in their life cycle to another (eggs to larvae to pupae to adults). Degree-days measure insect growth and development in response to daily temperatures. The accumulation of these degree-days can be measured over a period of time and used to estimate growth and predict insect development. Calculating degree-days allows us to predict when significant biological events such as the appearance of insect pests may occur or when they may reach a life stage that is damaging to a particular crop.…

Agronomy Day is a collaborative field day hosted by the Department of Crop Sciences in partnership with several academic units in the College of Agricultural, Consumer and Environmental Sciences (ACES). From nitrogen management to drone demonstrations Agronomy Day shares cutting-edge research with practical implications for your farm or business. CEU and CCA credits are available during tour stops.

The 2016 Illinois soybean story is similar to the corn story; current (July 24) crop ratings for both crops are similar to those we saw in 2014, when we produced the highest-ever yields for both crops. Illinois producers matched the 2014 soybean yield (56 bushels per acre) in 2015, despite the crop’s getting off to a very rocky start last year. Few surprises in crop production have been greater than that of seeing fields that looked marginal in July 2015 go on to produce 60,…

With the exception of a few cool and wet periods in May and some areas of southeastern Illinois that stayed wet and were planted late, the 2016 growing season has been very good so far. The Illinois corn crop was planted a little earlier than normal, stands are excellent, and the crop has had outstanding leaf color throughout the spring and into mid-summer. On July 24, 82% of the crop was rated good or excellent. That matches the late July rating in 2014,…

The 2016 Orr Center field day will be held on Wednesday, July 20, beginning with sign-in and refreshments at 8:00 AM. The format will be new this year, with three UI Extension specialists making presentations in indoor classrooms:

• Weed scientist Aaron Hager will talk about weed management
• Agronomist Emerson Nafziger will discuss crop conditions and nitrogen management
• Ag economist Gary Schnitkey will discuss crop income projections

Indoor sessions will be followed by a short wagon tour to look at crop conditions and some of the research trials underway at the Center.…
