Back-to-back microsprinkler nozzles spraying
Sustainable production of high quality fruit requires application of numerous pest management inputs to protect crops from disease and insect pests. However, reduced-risk pesticides require exceptionally uniform canopy coverage for successful disease and pest management. This presents a challenge for growers using tractor-based spray equipment in poor weather or to cover large acreages. We have been working in a multi-disciplinary research and extension team in New York to develop, evaluate, and optimize a resource-efficient solid-set canopy delivery (SSCD) system for a diversity of critical uses by tree fruit producers, including application of pesticides, pheromones, thinners, and foliar nutrients. The system is based on a central pumping station that pushes material down the row through tubing running along the the tops of tree canopies, where it is then emitted via microsprinkler nozzles, supplied by a central tank and pump. This project addresses a niche need with a novel technology that is so far relatively undeveloped in this cropping system; is capable of being implemented in a relatively short time; is interdisciplinary; can ultimately reduce dependence on application modes and rates of conventional pesticides; and has the potential to be more cost-effective than currently used application technology and could positively affect the economics of fruit production.

We have also adapted this approach for use in high tunnel bramble production systems, to optimize efficacy and efficiency in applying insecticides to control an invasive pest, Spotted Wing Drosophila.
