Both corn and soybean planting progressed at about normal speed into May, with 56 percent of the Illinois corn crop and 31 percent of the Illinois soybean crop planted by May 3. Unfortunately, the period of warmer, drier weather we have been hoping for has not yet materialized.
Over the ten days through May 5, about two-thirds of Illinois has gotten from 3 to more than 6 inches of rainfall. Temperatures have not cooperated very well,…
Wheat development in most in Southern Illinois fields is between Feekes growth stage (FGS) 9-10.5.1. Wheat in the central portion of the stage varies from FGS 6-9.
Stripe rust was detected in Eastern Madison County as of 5.5.20, and conditions are favorable for disease development and spread. This is a cool season disease that loves wet weather and temperatures in the high 40’s through the mid 60’s. Fields should be scouted for the disease, keeping in mind that it often starts in small pockets,…

Ample soil moisture and warming temperatures are promoting rapid growth and development of many early-season weed species. Most weeds currently growing in fields emerged last fall and successfully overwintered (winter annuals, biennials or perennials), but several early-season summer annual species recently have emerged. Existing weed vegetation should be controlled before planting by utilizing tillage, herbicides, or a combination of tactics so the crop can become established under weed-free conditions.
Field scouting to identify the weeds present and their relative densities will provide the information needed to tailor a burndown herbicide program for any particular field. …

March rainfall in Illinois ranged from normal to a couple of inches above normal, but the last week of March and first week of April have been relatively dry, and field operations are getting underway. The April 6 NASS report indicates that there were 3.1 days suitable for fieldwork in Illinois during the week ending on April 5, but no planting was recorded. As is often the case in early April, soils are wet over most of the state.…

As was the case a year ago, there have been limited opportunities to apply nitrogen fertilizer since last fall. Rainfall in Illinois through the first three weeks of March has been at or above average, and temperatures have been a few degrees above normal. Soils remain wet, and there is little in the current weather pattern to indicate that a drying period is on its way soon. Potential drying rates will increase as temperatures rise, though,…
