Black Cutworms Observed in Sangamon County
Some scouting in Sangamon County (IL) this morning revealed some Black Cutworm damage in corn plants where winter annuals were nearby. Based on early recorded BCW flights this is the right time to scout for damage. Sangamon and Macoupin Counties both observed significant flights in April.
It is recommended to watch this closely and prepare for a treatment if the damage threshold is reached.
