We had 0.5 inches of rain last weekend, and coupled with 80-degree weather all week, the crop has really progressed. Corn is at V4 to V8 and beans are at V2 to V6, depending on planting date. The crop as a whole looks good, but we seem to find more uneven stands of corn every day. We think the top-end yield may be dwindling on the corn planted in late April to mid-May with each day we don’t get rain. The early April-planted corn looks the best.

Warm temperatures have been very welcome and have helped spur crop development. While there has not been much rain over the last week, there is still plenty of moisture deeper in the soil from previous rains. Some insects are starting to show themselves in corn and soybean fields, but there are no signs of significant damage yet.

6 inches of rain in last 7 days. Just getting back in the field to get some spraying done. More rain expected next 5 days. Waterhemp going wild!

I’ve received several reports of injury from grape colaspis; in some cases it’s pretty extensive. Scout lighter textured soils and high points in rotated corn (or soybean following soybean), especially in areas that have had trouble in the past. The adults lay eggs in legumes; the partially grown larvae overwinter, then feed on roots of corn, soybean, or most other plants the following year. They resemble tiny white grubs.

Since last week’s update most of the region received 2”-5” of rain, so no planting has taken place.

Pictured here is a typical corn field planted on Memorial Day weekend, currently at V3, decent emergence during our relatively dry 3 week span, but some yellowing as a result of waterlogged soils.

First crop beans are still only partially planted, the typical field that did get in the ground is around VC-V2.

A typical wheat field in Marion county, largely golden, a few greens spots still remaining, grain is in dough stage.

The crop conditions across my 3-county area vary from V3 to V7 stage corn, and the soybeans range from unifoliate to blooming. Sidedressing of corn is completed with post-emergent herbicide applications still taking place. The corn and soybean crops look good with few problems.
The few wheat fields in the area are looking good where preventative fungicides were applied earlier. Wheat fields without preventative fungicide applications have numerous diseases present.
