Reinstating integrated mite control in apple orchards
Author: Elizabeth Beers
Published: 2007
Summary: This trial was conducted for three years in commercial orchards from Bridgeport to the Royal Slope. The treatments consisted of three newer codling moth insecticides (Assail, Calypso, and Rimon) compared to an OP standard (either Guthion or Imidan) applied to 1-4 acre blocks. The same treatments were applied to the same blocks in successive years. Mite populations in 2005 (Fig. 1a) were high in only one orchard out of five. The highest levels occurred in the Rimon treatment followed by Assail and Calypso. Very few differences were found in rust mite or predatory mite levels among the various treatments.
