Plots are looking strong and have been helped by excellent planting conditions and timely rain. Timely rain will need to continue as we are roughly 5 inches of precipitation behind the 30 year average and as plant uptake increases during the reproductive (R) stages. For instance, corn uses 0.25 – 0.32 inches per day at R1 growth stage. Many plots were planted early and have accumulated 150 GDUs (or more) above than the 30 year average. This combination has pushed us a week or two ahead of where we would “normally” be at for corn and soybean growth stages. The most surprising is how far soybeans have come. In some plots, we flowered before the Summer Solstice! Currently, we are in the R3 growth stage in soybeans, which usually occurs late July or early August.
We just applied a foliar fungicide to the corn and soybeans. CHS Acuvant™ was helpful because we were early on the corn. Acuvant is NPE-free; therefore, it will not cause arrested ear syndrome in corn. We are seeing significantly better canopy penetration as well as leaf coverage with Acuvant.
