Technical Abstract: Development of microencapsulated formulations of sex pheromones that can be applied through standard orchard spraying technology holds promise. Until recently products containing the sex pheromone component for codling moth have been short-lived. One approach to improve effectiveness of these products for codling moth is to target a greater percent of the active ingredient into the upper portion of the canopy. Studies were conducted to examine the deposition patterns of a typical air blast application vs. a low volume over-the-top application. The level of disruption with these 2 approaches was compared and contrasted with an application made directly on the ground. Capsules treated with a fluorescent pigment were added to the spray tank with the 2 canopy treatments. Fifty leaves from the top and bottom of each plot were collected and examined under a blacklight. Within each plot 5 female-baited traps and 1 trap either baited with a Consep Inc. 1x or 10x Biolure.
