thAbstracts ofthe 77 Annual Western OrchardPest &Disease Management ConferenceImplementationThe California walnut IPM expansion projectPatrick Weddle and Larry ElworthCenter for Agricultural Partnerships, Asheville, NCAbstract: The Center for Agricultural Partnerships (CAP) in cooperation with growers and theirorganizations, crop consultants, researchers and farm advisors has developed a project toimplement sprayable mating disruption and other new technologies on 25% of the walnutacreage susceptible to codlingmoth (CM) infestation(approximately 25,000 acres by the end ofthe fourth year). During year 1 (2001) the project's potential for success was researched, projectobjectives were developed, the project architecture was designed and cooperators wereidentified. In year 2 (2002) baseline surveys of cooperators were conducted, work plans wereformulated and the pilot field project was initiated with regional coordinators, 3 key pestmanagement consultants and 8 grower cooperators on 900 commercial walnut acres statewide.2002 results showed that cooperators have a continuing commitment to testing the targettechnologies under commercial field conditions, that mating disruption, though more expensivethan conventional spray technologies, does have potential as a tool for CM management inwalnuts, that the DA lure significantly out-captures pheromone baited traps in mating disruptedwalnuts and that there is continued interest in expanding the project into 2003. Discussion of theproblems and pitfalls of this approach to wide-scale commercial implementation will also beprovided. Codling moth is one of the key pests of walnuts, infesting 60% of the more than200,000 acres in California. Uncontrolled codlingmoth can lead to economic damage of up to40% of the crop. The walnut crop in California was valued at $346 million in 2001.Co^xri'-0Y^^^ CWI-OIImplementationDevelopment ofPalm Pilot based spray recommendation databases for deciduous fruitsVincent P. Jones and Gary GroveWashington State University, Tree Fruit Research and Extension Center, Wenatchee, WAAbstract: Palm OS databases were developed to help agricultural consultants make decisions forIPM programs in deciduous fruits and grapes. The databases allow the user to view therecommendations by time of season and pest or disease. Each record for a pesticide includesrates, information on other pests controlled, effects on natural enemies, re-entry interval, pre-harvest interval, bee toxicity and any use restrictions. The disease databases are similar, but alsoinclude cross-resistance factors that are a serious concernwith disease management programs.The inclusion of this information in a small, inexpensive, and easy-to-use hand-held computerallows the user to compare pesticides to maximize control while considering other use factors.15-17January 2003, Hilton Hotel, Portland, OR *> Publ. byWashington State Univ., Pullman, WashingtonPage 20
