Caption: Sandwich Fair Corn entries Sept 2024
SYNOPSIS

Another dry week, in travels across northeast Illinois we see both green corn and soy fields and in others, plants that have browned, dropped leaves and are likely only weeks from harvest. We have had reports of hand shelled corn samples near 30% moisture. For areas that had heavier soils, received timely rains and had higher water holding capacity, the yields will be impressive. A visit to the Sandwich Fair this week judging corn entries demonstrated sizeable ears. If they are representative, it will be interesting to see final yields from these locations. Somewhat of a surprise, we are finding pockets of white mold in some soy. Even though the symptoms (dead plants) are easily visible now, the initial infection took place when the soy was in the R1 to R3 stage. Harvesting white mold infected soy last and then cleaning your combine can limit the spread of sclerotia, the overwintering structures of this disease, to other areas or fields. Tar spot continues it spread in corn, even in earlier fungicide treated fields.
