The insect situation has not appreciably changed since last week. Codling mothremains the key pest of concern throughout the region. Cumulative degree-days range from about 445 in Henderson County to about 656 in Cleveland County, which indicates we are in the midst of first generation egg laying. Overall, populations have been quite low throughout the area. With unseasonably warm weather forecast for the next few weeks, first generation flight should be completed much sooner than normal;  the main period of activity should be complete in about a week in lower elevations such as Cleveland County, and about two weeks in Henderson County.

The warm spring has also accelerated tufted apple bud moth development, with about 550 DD accumulated since biofix in Henderson County. A single insecticide spray made between about 700 and 1200 DD will provide season-long control of TABM. Insecticides of choice include Altacor, Delegate, and Intrepid, all of which are highly effective against this pest.
