Progress Report:
Sprayable (3M Canada) and emulsion (Confuse-OFM) pheromones were evaluated in comparison with a conventional insecticide program and untreated check for the control of oriental fruit moth in 28 acres of peaches. Comparable moth capture occurred in the 3M Sprayable, Confuse-OFM and conventional plots, which was much lower than in the check plot. Terminal and fruit injury were significantly higher in the Confuse-OFM than in the 3M Sprayable plot, and slightly higher in the 3M Sprayable than in the conventional plot, where no injury was found. In a 24 acre peach orchard, Isomate LPTB mating disruption dispensers (250/acre) were evaluated on 10 acres in comparison to a conventional application of Lorsban 4E on 14 acres for the control of lesser peachtree borer and peachtree borer. Isomate LPTB resulted in excellent trap shutdown of both borer species. Injury (LPTB pupal exuvia) in the Isomate LPTB plot was approximately half the level of that in the conventional plot. In a 12 acre orchard, organic (8 acres) and IPM (4 acres) pest management strategies were evaluated on processing apples. The organic program consisted of Isomate-C/OFM mating disruption dispensers at 400/acre (for codling moth and oriental fruit moth), Aza-Direct, Dipel and Surround. Asana, Imidan and Intrepid were used in the IPM program. Foliage-feeding insects, except for Japanese beetle, were lower in the organic plot. Fruit injury in the organic plot was slightly higher for codling moth, oriental fruit moth and San Jose scale, and twice as high for tufted apple bud moth as that found in the IPM plot, with similar injury levels for tarnished plant bug and plum curculio. Mesa acaricide/insecticide with oil provided more effective control of European red mites than combinations with LI-700 or Silwet, which were comparable to Mesa applied alone. MANA-300 and Apollo provided comparable control of European red mites following an early season application. Applications of BAJ2740 acaricide at 3 and 4.5 weeks after petal fall resulted in better control of European red mites than earlier or later applications.

Impact:
Mating disruption pheromones have the potential to provide insect control comparable to insecticides without the associated problems of chemical residues on food, toxicity to man and natural enemies, lengthy restricted-entry intervals, and environmental contamination. Development of a successful organic pest management program for apples would provide producers with the opportunity to enter a niche market with potentially greater returns.
