Project Number: 6202-22000-023-00
Project Type: Appropriated

Start Date: Sep 24, 2003
End Date: Sep 23, 2008

Objective:
1) Develop and integrate GIS, GPS, and other systems for efficacious precision application; 2) develop technologies that account for material released during crop spray applications; 3) develop and evaluate nozzles and other application technologies and spray formulations with emphasis on reducing driftable fines and improving efficacy; 4) determine effects of meteorological conditions on off-target movements of sprays; 5) develop and evaluate systems for aerial delivery of new crop pest management materials.

Approach:
Utilizing engineering and biological principles, laboratory and field studies will be conducted to evaluate the effects of various aerial application parameters, such as droplet size spectrum and equipment, on efficacy and off-target movement of crop production and protection materials. Efforts will focus on maximizing efficacy and spray deposition, through equipment or formulation modifications, so minimal amounts of pesticides will be needed for crop production and protection. Spray deposition and movement will be quantified using various plant and artificial collectors in conjunction with chromatography and spectrofluorometry. Pest control efficacy will be evaluated using lab and field assessments. Novel application equipment, spray models, and product formulations will be developed.
