The results from OrchardMAX help you make every drop count when airblast spraying apple trees. It uses the Crop-Adapted Spraying (CAS) model to adjust the pesticide rate-pre-planted-area to match the size, shape and density of the trees. The app will calculate a sprayer prescription for each block of trees. That way, when combined with a properly calibrated sprayer, all trees should receive a consistent dose. Spraying according to this app will give the same control as a conventional application but will save a great deal of potentially wasted spray.
