INTELLIGENT SPRAY APPLICATIONS IN ORNAMENTAL NURSERIES IN TENNESSEE AND SOUTH CENTRAL REGION STATES
Application Technology Research Unit
2012 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 Tennessee ornamental nurseries for the development of models to predict top insects and disease pressures; field experiments in a Tennessee leading nursery 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.
Six site visits were made to survey top insects and diseases in Tennessee ornamental nurseries and identify potential cooperators for the new intelligent sprayer trials in the 2013 and 2014 growing seasons. The intelligent sprayer development and benefits were presented at Tennessee Nursery and Landscape Association (TNLA) Field Day, Tennessee Landscape maintenance short course, Green Industry Express in Chattanooga, Tennessee Agricultural Professionals Associations, TNLA winter educational program, East Tennessee Nursery and Landscape Association, and the Bernheim Arboretum & Research Forest in Clermont, Kentucky.
This project addresses critical elements for the development of precision sprayer technology envisioned in ARS parent project Objective 1 “Develop precision sprayers that can continuously match canopy characteristics to deliver agrichemicals and bio-products accurately to nursery and fruit crops”.
