Abstract

Morestan applied at the white bud, calyx, or white bud plus calyx stage on Bartlett pears gave good control of the pear rust mite, Epitrimerus pyri (Nal.), and prevented fruit russet caused by rust mite feeding. A June spray of Morestan or ethion also controlled the mite but did not prevent fruit russet. During the white bud and calyx stage, the rust mite is found at the base of leaves and flowers but moves to the fruit shortly after the calyx stage. By early June, it can cause considerable fruit russet, especially on the calyx end of the pears.
