Planters were rolling over the weekend in parts of Champaign County, but rain from Monday into Tuesday has kept everyone out of the field since. Most fields I passed during my survey of the northern half of the county had been planted, but maybe only 10% to 15% had crop emergence. Cooler weather and relatively wet soils over the past couple of weeks have made the crop slow to emerge in many fields, with some taking more than two weeks after planting. Most soybeans are just starting to get out of the ground, while a few corn fields I saw were a bit further along, near the V2 stage. The one wheat field I found was still in the stem elongation phase, with the flag leaf visible on some of the more advanced plants.

I’m looking forward to another growing season and crop reporting in Northeast Illinois. April and May precipitation has slowed planting progress compared with other regions of Illinois. I’m estimating almost as much seed is still in the bag as is in the ground. On suitable days for planting, reports received suggest local farmers actively planted both soybeans and corn. The practice of planting soybeans ahead of corn acres has been adopted by many. Whether corn or soybeans, I was impressed by the acreage planted in a limited time frame. Despite planting date, low accumulations of GDDs have slowed crop emergence.

With limited emerged crops, we will highlight insect pests found in alfalfa. While sweeping alfalfa, we netted alfalfa weevil larvae, aphids and bean leaf beetles. We will continue to monitor leaf feeding in the alfalfa crop to determine whether a management threshold is reached.

Fieldwork and planting have been ongoing once fields dried enough following the significant rainfall events experienced in the area in mid-April. Although two weeks ago we experienced a number of uncharacteristically warm days, the weather this week continues to vary, as some days have been relatively warm but many nights have been relatively cool, with some even falling below freezing. Those who have recently planted may see slower emergence due to the consistently colder nighttime temperatures. However, the next week should bring temperate weather to facilitate further planting progress and good conditions for crop emergence across the area.

Roughly 75% planted after an early planting season. Crop that’s up is in the “ugly duckling” stage and needs some heat to really get going. Wheat spraying wrapped up for the most part, and many are very optimistic about the wheat crop. Finding ladybug pupae in soybean fields!

Our region received between 0.4 and 1 inch of rain on Monday, April 27, and the majority of the week was cool and overcast with small chances of rain every day during the week. Since the first part of the week was not optimal for fieldwork, we found a way to stay busy doing projects like aerial seeding a new pasture. Farmers are pushing to get more done before the next rain. Fieldwork picked up toward the end of the week, allowing us to accomplish more than anticipated, as well as assisting in planting corn research plots at the FS Technology Learning Center in Galesburg.

3.61 inches of rain for the week of April 26 has put a halt to field operations. Early planted soybeans look excellent. Early corn has emerged and is off to a good start, despite the cooler temperatures. Most corn planted in the window before the large rain still has not emerged. Replant operations appear to be likely on those acres. Soft red winter wheat has headed out, and anthers have appeared, triggering aerial applications of head scab fungicide.
