Crop-Adapted Spraying: A Proposed Method to Reduce Coverage Variability in Apple Orchard Spraying

摘要

AN ORCHARD SPRAYING SCENARIOPicture this: An orchardist following an IPM protocol identifies a pest that poses an economic threat. This is no surprise because it's an annual pest and spraying is only a matter of when, not if. The operation is 150 acres and runs three airblast sprayers; two have a tower and one does not. Multiple varieties are planted in several blocks on different root stocks, and they are at different stages of maturity. The newer blocks are trellised high-density trees, and the older blocks are semi dwarfs on different row spacings. Just for fun, let's imagine the pruning team hasn't finished yet, so some trees are un-pruned.
