A COMPARISON OF TEBUFENOZIDE (CONFIRM®), DIFLUBENZURON (DIMILIN®), ESFENVALERATE (ASANA®) AND CHLORPYRIFOS (LORSBAN®) FOR CONTROL OF CODLING MOTH, CYDIA POMONELLA IN WALNUT, JUGLANS REGIA

Codling moth is a major insect pest of walnut, Juglans regia in California. The insect growth regulators Confirm® and Dimilin® have the potential for codling moth control without disruption of biological control. In test orchards, Confirm®, Dimilin®, grower’s standard (Lorsban® plus Asana®) and a modified check treatment (Asana® in the 1B flight) were tested in 1995, and Confirm® and Lorsban® were compared in 1998. The untreated checks suffered significantly more damage from first flight codling moth in both years than did the grower standard, Confirm® or Dimilin® treatments. Confirm® and Dimilin® can be used effectively where codling moth populations are moderate, and where preservation of beneficials is very important.
