Weeds and Their Management in 2020
No sooner have many unpleasant memories of the 2019 growing season begun to fade than we find ourselves looking ahead to contemplating potential residual weed management challenges in 2020.
Winter Annual Weed Species
Delays in planting the 2019 crop often accompanied delays in controlling existing stands of winter annual weeds prior to planting. The obvious and unwelcome result was that seed production by winter annual species likely was a high in 2019 as any spring in recent memory. …

Nutrient movement off frozen and snow-covered soil
Snow has now fallen throughout much of Illinois, and temperatures have dropped going into the last weeks in 2019. With the recent Illinois Nutrient Loss Reduction Strategy biennial report highlighting P and N levels in Illinois waterways, this is a good time to review the application of nutrients on frozen and/or snow-covered soils.
Last spring, after a short and often-muddy fall fertilizer season, a considerable amount of fertilizer—mostly P in the form of DAP or MAP and K as KCl—was applied during the first week of March when the soil surface was frozen.…
Wet grain, test weight, and late corn harvest
According to NASS, 20 percent—some 2 million acres—of the 2019 Illinois corn crop was still in the field on November 17. Following unprecedented delays in planting, the warm weather in September helped move the crop towards maturity, and frost did not come earlier than normal. So most of the corn in Illinois was at or close to maturity by mid-late October, but temperatures have been below to much-below normal over most of the past month, and this has delayed drydown of the crop.…
Statewide Corn and Soybean Survey Indicate Lower Insect Populations in 2019
The Illinois Statewide Corn and Soybean Insect Survey has been occurred in eight of the last nine years (2011, 2013–2019). These surveys have been conducted with the goal of estimating densities of common insect pests in corn and soybean cropping systems. In 2019, 40 counties representing all nine crop reporting districts were surveyed, with five corn and five soybean fields surveyed in each county.
Within the soybean fields surveyed, 100 sweeps were performed on both the exterior of the field (outer 2 rows) and interior (at least 12 rows beyond the field edge) using a 38-cm diameter sweep net.…
