2010 Annual Report 1a.Objectives (from AD-416) Assist development of an expert system for the intelligent sprayers by investigation of top insects and diseases in ornamental nurseries and field experiments to test the new spray system. 1b.Approach (from AD-416) Literatures and research reports will be reviewed and nursery fields will be surveyed to determine top insects and diseases in ornamental nurseries in Oregon and western states for the development of models to predict top insects and disease pressures; field experiments in three Oregon leading nurseries will be conducted to evaluate performances of new intelligent sprayers to control the top insects and diseases with reduced pesticide rates; educational materials will be delivered through workshops, field demonstrations and grower meetings to teach spray applicators how to use the new spray technologies. 3.Progress Report An experimental intelligent sprayer was delivered to a commercial nursery in Oregon for field tests. The cooperator has determined two top insects and one top disease for the evaluation of the new sprayer performance. Document monitoring activities for the project: Regular email communications and phone calls are used to discuss research activities. A written report on the project progress is also delivered annually.
