[Crop Note] current soybean stage (12 Sep 2023) at Champaign in IL, USA


Agronomy note
□ Sowing date: 2023/05/18
□ V4: 2023/6/28
□ Flowering: 2023/08/01 
□ R6: 2023/09/12

Three weeks ago, there was an insect problem on soybean leaves caused by Japanese beetles. After flowering, applying insecticide may not be advisable, and therefore I expressed my objection to such applications among several groups sharing the same field. Unless pods are damaged, it is less likely to affect grain yield at around R5.

The current growth stage is R6 (full seed), and now I see some pods damaged by insects. It is not widespread, but I observe some pods sporadically.

I might consider harvesting earlier than initially planned to prevent further damage to the pods.
