Abstract

Delayed dormant applications of endosulfan plus oil or ethion plus oil gave excellent control of both the pear leaf blister mite. <i>Eriophyes pyri</i> (Pgst.). and the pear rust mite. <i>Epitrimerus pyri</i> (Nal.) Lime sulphur as a dormant spray gave excellent control of the pear leaf blister mite but the delayed dormant application gave poor control. Both applications of lime sulphur gave good control of the pear rust mite.
