Workgroup Information European Pear |
|
| $3,000 | |
| Summary | The European Pear Workgroup continues to focus more on horticulture, particularly new varieties, rootstocks, and planting systems to accommodate labor efficient orchard operations using orchard platforms and other means. There is also new information being developed on using oil to mitigate the effects of poor chilling and increase fruit size and quality. This occurs coincidently with the loss of the Extension Specialist covering pears and downsizing of applied horticulturists at the campus level. County-based advisors are increasingly working with Pacific Northwest colleagues with similar interests and goals. A productive relationship with the Agricultural Ergonomics Research Center has also been established to study platform machines. Pest management activities continue to focus on alternatives to broad-spectrum pesticides, e.g. organic codling moth (CM) control, development of a new bactericide, i.e., kasugamycin, for fire blight management, secondary pests in mating disruption programs etc. Resistance to streptomycin is widespread and terramycin resistance has been recently described in the state for the first time worldwide. Resistance to scab fungicides is also of major concern to growers.Statewide surveys have been initiated in the last two years. A major accomplishment is the release (in spring 2007) of the new Pear Production and Handling Manual. |
