SYNOPSIS

The warm temperatures across the county this week appear not to have slowed down crop progress at all. At the Hartsburg Research Plot in northern Logan County, soybean growth is mixed throughout the field. In the parts where there was standing water, plants are in the V5 stage, while the rest of the field is at V10. In the parts of the field that had standing water, there are many empty spaces where plants have not developed or failed to emerge. Volunteer corn is the most-present weed at the Hartsburg Research Plot this year, given the late planting date. Other weeds such as Palmer amaranth, Redroot pigweed, and Common waterhemp are also starting to show themselves. While there are Japanese beetles in the field too, they do not appear to be causing significant damage to the leaves, with only a handful of plants and leaves showing major signs of damage.
