1) To conduct validation research showing that the systems approach to prevent crabapple decay is effective using a combination of disease inoculum removal from infected ‘Manchurian’ crabapple pollinizer coupled with appropriate post-harvest fungicide treatments and rigorous pre-export inspection can reduce Neofabraea, Phacidiopycnis and Sphaeropsis decay to non-detectable levels. 2) Improve growers’ understanding regarding the incidence and management of bull’s eye rot in apple orchards. 3) Develop a decision support system to aid pear growers and packers in identifying and managing orchards that are at high risk for post-harvest fruit infection with Phacidiopycnis pyri and Sphaeropsis pyriputrescens.
This project will provide the information to determine the efficacy of the proposed systems approach mitigation for Phacidiopycnis and Sphaeropsis in apple orchards; identify an appropriate alternative to ‘Manchurian’ crabapple as an early season pollinizer in apple orchards; help growers understand the most effective ways to manage bull’s eye rot in apple orchards to prevent losses; and use existing research coupled with field surveys to identify characteristics of pear orchards at high risk for infection by Phacidiopycnis pyri and Sphaeropsis pyriputrescens.
