Current Progress in Developing a Fixed-spray Application Sytem for High-density Plantings

The application of pesticides to fruit throughout the Northeastern US, as in the rest of the world, gives rise to concern, primarily due to inaccurate application, which often results in high residues and environmental pollution. Inaccuracy, due to over/under application, may result in high levels of disease or insect activity. Air and water pollution is a major concern due to pesticide drift. There is also a growing concern for food safety and accountability among consumers who purchase fruit. Surveys of fruit growers of New York, based upon stakeholder input, show that evaluation of sprayers, sprayer management and fruit coverage issues are a research priority in tree fruits and apples in particular. Priorities developed by members of the Northeastern IPM Fruit Working Group include sprayer and pesticide application resources (evaluations, calibration, best use patterns, etc.).
