Trees are pruned during dormancy so that spray penetration and air circulation are adequate, and diseased wood and fruit mummies are removed.
Pruning debris is removed or destroyed using flail chopping or another method such that no residue is present after one year.
Summer pruning is done on densely-foliated, vigorous trees.
Orchard plantings include dwarfing rootstocks planted at high density using a training system that will reduce spray volume and improve spray deposition.
