Technical Abstract: Studies were conducted in replicated small plots of apple comparing the efficacy of ULV sprays of Checkmate CM-F alone and in combination with Asana, Assail, or Imidan. A five-spray program of pheromone + insecticides using half rates of Assail or Asana were significantly more effective than spraying pheromone alone and equivalent to a four-spray, air blast insecticide program using full rates. Imidan at 1.0 lb per acre plus pheromone gave intermediate results. All ULV programs had lower phytophagous mite: predator mite ratios compared with plots treated with air blast applications of each insecticide. Interestingly, this ratio in both the Assail and Imidan treatments was not different than in the pheromone-only or untreated plots. ULV Assail applications were also very effective for control of white apple leafhopper. A new technique coined PULSV (Pulsating Ultra Low Spray Volume) was developed in 2006 for applying the microencapsulated pheromone formulation. PULSV allows growers to concentrate the deposition of microcapsules in the canopy to create 1,000’s of attractive point sources in the orchard. Future studies will examine the effectiveness of the PULSV approach.
