Most projects have been targeted atcodling moth, primarily through the use of mating disruption to replace organophosphateinsecticides. Pear psylla, another important pest of pear, is amenable to areawide management, inthat it is highly dispersive and has a number of potential natural enemies in surrounding nativewoodland. Establishing organic orchards or orchards using soft management practices amongconventional orchards has often been difficult in that pests readily migrate in from theconventional orchards, yet natural enemy immigration is limited by the pesticide use in thosesame conventional programs. Organic pest management on an areawide basis could providemore opportunities for immigration of biocontrol agents. In 2002, an Areawide OrganicManagement Program was established on 310 ac of contiguous pear, surrounded by nativevegetation. Organic pest management practices were implemented for insect and mite controlthroughout the project, however other organic practices were not required (e.g., nutrient, rodent,and weed management were often by conventional practices). Overall, there was a reduction inpesticide use and an associated reduction in insecticide costs. This program will be expanded in2003.

The first is to r&x*implement arthropod management without the use of organophosphate and carbamate ^z3ri^-/insecticides. The second is to achieve pest control equal to or better than the standard approach ^^^rTfused during the past 30 years. The third is to keep pest control cost equal to or lower than the ^O^McKstandard broad-spectrum insecticide approach. Fourth, grower adoption is necessary for success. *The program has involved 7 farmers with 11 farms over 4 San Joaquin Valley counties. The 3- dK^year comparison of insect damage has resulted in an average of 7.4% and 9.5% between the ^GAlliance Program and the Standard Program, respectively. The average cost for pesticides in theAlliance Program is $183. The average cost for pesticides in the Standard Program is $190.Onlyone orchard utilizing the Alliance program has required supplemental use of broad-spectruminsecticides in 2002.
