With the uncertainty of fruit loads and extended bloom period, many growers are just now applying a petal fall spray. Recommendations for petal fall were outlined in the April 15 update, with an emphasis on control of plum curculio.

Codling Moth:  In lower elevation orchards such as Lincoln and Cleveland Counties, codling moth degree-day accumulations have increased to 300, while in Henderson County they are only about 180 DD. First egg hatch begins at about 250 in orchards with moderate to high populations. However, in orchards with low populations, which includes most commercial orchards, initial applications can be made at about 350 DD. In Henderson County, 250 and 350 DD are predicted to occur on May 9 and 15, respectively. In Lincoln county 350 DD is predicted for later this week.
