Green apple aphids are building up their colonies, but the numbers are still relatively low. White apple leafhoppers and potato leafhoppers are spotty. People who are planning on using Confirm or Esteem for obliquebanded leafrollers will be treating by the end of the week. Growers planning on using SpinTor or Bt will be closing in on a target date some time next week. A significant increase in the numbers of spotted tentiform leafminers indicates the second-generation emergence.
Pears have an excellent crop potential.
Adult pear psylla has been spotted. Sweet cherry fruit is sizing well and beginning to show color. Brown rot control is increasingly important. Frequent rains that the forecast calls for will contribute to fruit-splitting potential and increased brown rot infections. Tight and complete coverage is essential.
