Wheat Insects – What to Watch for This Spring

Consider adding some insect scouting to your wheat management routine this spring if you are not doing so already. While damaging insect pest infestations are pretty sporadic in Illinois, missing one can be costly. The first step in managing these infestations is knowing what to look for.… Read more

Variable vs. Uniform Seeding Rates for Corn

Along with colleagues from Ohio State University, we took a look recently at data from a lot of corn plant population trials in both Ohio and Illinois to see if we could come up with estimates of the value of variable-rate corn planting.… Read more

Grape Colaspis in Corn and Soybean: a Pre-Season Primer

Grape colaspis is a common insect, but it only occasionally affects corn and soybean production in Illinois. However, 2018 was that rare year where “outbreak” levels of infestation occurred in parts of the state, resulting in stand reductions and, in some cases, replanting of damaged areas.… Read more

Cool season viruses in wheat

Currently, most small grains are approaching jointing or just past jointing in many parts of the state.  Now is the time that you most likely will start to see early season viral diseases in some fields, specifically Wheat Soilborne Mosaic Virus and Wheat Spindle Streak Virus.… Read more

Another Look at Soybean Planting Date

As we wait for things to dry out so planting can begin in Illinois, I’ll provide an update on soybean planting date, including addition of some recent data and more detail on what planting date studies are telling us.… Read more

Early season diseases in soybeans

Now that the soils are warming, some producers are discussing planting soybeans in the ground.  When considering early planting of soybeans, there are two diseases that should be considered: 1) Sudden death syndrome (SDS)  and 2) Pythium root rot (PRR)

Both SDS and PRR are favored by cool, wet weather. … Read more

Remember to check your hybrids for tar spot ratings, scout your fields

It is that time of year again.  Soon corn will be in the ground, and the 2019 field season will be taking off.  It is no surprise that I spent the majority of my time on the speaker circuit discussing tar spot in corn. … Read more

Cooperators sought for Insect Trapping and Field Surveys

We are starting to look for cooperators that are willing to place and monitor traps for black cutworm and true armyworm this spring and European corn borer, corn earworm, fall armyworm, and western bean cutworm this summer.… Read more

Managing Nitrogen for Corn in 2019

The fall of 2018 and so far in 2019, there have been limited opportunities to apply nitrogen fertilizer. Average rainfall through the first 25 days of March ranged from a little less than normal in the northern half of Illinois to an inch or more above normal in south-central Illinois.… Read more

Waterhemp Resistance to Group 15 Herbicides

The continual evolution of weed species and populations resistant to herbicides from one or more site-of-action groups represents one of the most daunting challenges facing weed management practitioners.  Waterhemp has evolved resistance to herbicides from more site-of-action groups than any other Illinois weed species, including resistance to inhibitors of acetolactate synthase (ALS), photosystem II (PSII), protoporphyrinogen oxidase (PPO), enolpyruvyl shikimate-3-phosphate synthase (EPSPS), hydroxyphenyl pyruvate dioxygenase (HPPD), and synthetic auxins. … Read more
