The 2022 Weed Control Guide for Ohio, Indiana and Illinois contains 232 pages of weed management information, including weed response ratings for corn and soybean herbicides. Information and recommendations for managing weeds in small grains and forages are included, along with specific information about,…
As of October 31, 81% of the 2021 Illinois corn crop and 75% of the soybean crop had been harvested. That’s close to the 5-year average for corn, but 11 percentage points less than the average for soybeans. While harvest started early and with low grain moisture,…
After an early start to fall harvest in 2021, widespread rainfall over most of Illinois in the second week of October slowed harvest progress; by October 17, 62% of the corn crop and 51% of the soybean crop were harvested, compared to 5-year averages of 59 and 62% for the two crops,…
With warm and dry weather prevailing over the past month, harvest of the corn and soybean crops has proceeded at a brisk pace in Illinois. By October 1, 41% of the corn crop and 32% of the soybean crop had been harvested;…
Have you had issues with dectes stem borer in soybean over the last several years? We are kicking off a project this fall to better understand dectes stem borer populations in Illinois – where they are most common, how severe they are,…
Over the last two weeks, reports of fall armyworm (Spodoptera frugiperda) activity in southern and western Illinois have been on the rise, with reports of severe injury in some cases. The Southern U.S. has had a big year for fall armyworm (you can read more about their experience here,…
In an article posted last week I described the effects of rainfall and standing water on corn plants, especially corn roots, and what this might mean for corn crop prospects. Here, we’ll consider the extent to which damage from wet soils can be addressed by management during the second half of the 2021 season.…
The 2021 cropping season in Illinois (and the Corn Belt) continues to be a story of haves, have-nots, and have-way-too-much with regard to rainfall. In the first three weeks of June, nearly all of Illinois had below-normal rainfall, and concerns about dryness increased.…
Nearly all herbicide labels (soil-applied or postemergence) have rotational crop intervals that specify the amount of time that must elapse between herbicide application and planting a rotational crop. This becomes particularly important with late-season herbicide applications, and when soil moisture is limited.…
Japanese beetle emergence is beginning throughout Illinois. While they get a lot of attention every year, the real impact on corn and soybean yield is generally pretty minor. (If you have roses, sassafras trees, or a golf course, different story). A few things to keep in mind when you scout:
Check the field interior as well as the edges.…
