Each week, I put out a request to crops educators and specialists from the University of Illinois to compile an update to share with the entire state. We hope you find this information useful. If you have any questions or suggestions about the format or any feedback in general about these updates, please email me (firstname.lastname@example.org).

I’ve received a report of some economic stand losses from black cutworm in the area around Effingham County; in particular, scout fields that had problems with winter annuals and/or a late burndown relative to planting. If you’re considering an insecticide application, verify that the larvae are still present in the field, as in many areas they are likely close to pupating. Fireflies are coming out in east central Illinois and have been to the south for a week or so, indicating rootworm egg hatch has begun.

Maroa to Monticello transect did not find any unplanted fields. Scattered reports of replant mostly from specific planting dates. Herbicide application was primary field activity, with some anhydrous tanks on the move.

Moving into June most of the corn and soybeans have been planted in NW Illinois. Consistent rainfall events have been welcome, assisting with germination and emergence without hindering field operations too much. Soybeans are approximately VC/V1 with corn approaching V3. Conditions after planting seem to be good with favorable stand counts being observed. A good residual herbicide application post-emergence may be needed in some fields where planting took precedence. Be sure to look at a recent article by Dr. Aaron Hager to help with the decision-making process.
Pasture condition looks good, having benefited from ample rainfall over the last month. Where appropriate, first hay cuttings are taking place when conditions are favorable.

Despite a forecast for a wet week and we have dodged the rain. Late last week we had a total of 0.3″ and this week we haven’t even had a tenth. Temperatures and humidity dropped on Thursday with highs close to 80. Most planting is done and most of the fields I have seen look good and warm weather and good moisture have made for quick emergence. Wheat is also looking good and so far any head scab observed has been limited in occurrence and severity.
