Welcome to SmarterAppleSpraying!

The Intelligent Sprayer is the creation of a team of USDA-ARS engineers at Wooster, Ohio, led by Dr. Heping Zhu. It has been tested on nursery trees, peaches, grapes, and other large-canopy crops, and is now available commercially for retrofitting standard airblast sprayers. Our study is the first to evaluate the Intelligent Sprayer for control of the full range of pests and diseases on apples during the whole growing season.
