Hello Art, I would contend that a well-planned properly filled out orchard of dwarf trees (say from seventh year) has just as many leaves as the majority of orchards with standards. If this were not the case the dwarf orchard would not be able to out-yield the standard orchard in tons of crop per acre, which the dwarf orchard clearly is able to do. I think that TRV is over simplistic and really only useful when considering younger dwarf orchards where the volume has not filled out, or older orchards with missing trees etc., or perhaps badly planned orchards where the space is not filled due to trees being spaced too widely.
I would certainly hope that new pesticides are researched on fully filled-out dwarf orchards, and not on trees in their second or third leaf.

Sorry everyone. If research on older pesticides was done on standard trees and semi and dwarf trees require less material due to less canopy and newer pesticides were researched on small trees why wouldn't larger trees require more material per acre? Reverse tree row volume if you will. Art Kelly Kelly Orchards Acton, ME
