Most corn is in R1 with a few fields at R2 (blister) stage. R2 stage corn looks to have had good pollination take place. Soybean fields are in or approaching the R3 stage with good pod set on the stems. Noting a wide variety of defoliators in the fields but not at damaging levels. At this time, I have not seen leaf diseases of note on corn or soybeans.

Corn, soybeans, and forages are stressed with growth stunted. V10 growth stage corn is barely shoulder high at its highest point. Soybeans planted in 15-inch rows at the end of April are finally closing over. Most corn is in the V7 – V10 growth stage with some at V11. Soybeans vary from V7 to R1. Wheat harvest is just beginning in this part of Illinois (DeWitt, Macon & Piatt Counties). Second cutting hay looks to yield about 50% of first cutting on the average across the the area. Pastures and roadsides are brown where grazed or mowed.

My area is dry, but cool nights and cloudy or hazy days are helping to keep stress on the lower end. Corn fields are in growth stage V6 to V10+ for the majority. Corn height is shorter than normal. Soybeans fields vary from V4 to R1 and are shorter then usual. Area wheat fields are looking good with leaf leaves clean and green with harvest getting close.

The cool, low humidity nights of late May have caused “silver leaf” to show in local corn fields. According to Purdue University, yield effects are negligible. Corn is mostly in the V5-V7 stage and soybean plants at about the same stage, V6-V7. Topsoil is dry down to 4+ inches fields in fields at the V6-V7 growth stages. Noticing along field edges increasing numbers of amaranth species becoming evident and this family of weeds tolerates hot, dry weather well.

Corn is in the V6 to V2 growth stage, except for replanted areas. Soybeans are V3 to V1 growth stage. Crusting in some soybean fields is causing stand variability where planting was done just ahead of the early May heavy rains. Rotary hoeing may have paid in some of these fields. Currently farmers are side-dressing N in corn and are making post-emergence herbicide applications. The past week saw only minor amounts of rainfall across DeWitt and Macon Counties.

In Piatt County, the heavy rains of May 6 -8 have caused some emergence issues in fields planted ahead of those rains. Some fields have been rotary hoed and some not. Wheat fields have finished flowering and look good. Early planted crops are growing well, corn is at V4 and soybean at V2. Ponding damage is visible in poorly drained areas of fields. Only light rain has fallen in the past week.

2023 planting is nearly done with most farmers in the area finished planting. The dry April weather has allowed spring planting to progress quickly. The cool temperatures for the second half of April has slowed emergence and plant growth of plants that have emerged.

All crops are planted. Corn growth stages vary from emerging to almost V3 with third leaf almost fully developed. Soybean are similar varying between just breaking through the ground to first trifoliate.
