In the attached graphs for CM degree day accumulation in central Virginia you will note that the last optimal timing for managing 2nd brood CM larvae using products indicated by the green lines is within the next 1-3 days, based on model predictions using a biofix of April 17 and 22 for the Red Hill and Batesville areas, respectively. After 2nd brood, the model is not used, so management decisions can be based on whether or not CM captures in pheromone traps exceed the threshold of an average of 5 moths/trap/week.
