Sprouting elimination of decapitated peach trees

摘要

The effects of the herbicides Garlon, Roundup, ammonium sulfate (as dry fertiliser or sprayed liquid), fresh manure, and organic matter derived from wild grass, on elimination of re-sprouting by cut peach trees cv. Papagianni, grafted on the rootstock GF677, were recorded. Complete elimination of re-sprouting from decapitated peach trees was achieved following treatment with Garlon, Roundup or ammonium sulfate (as dry fertiliser). Treatment with fresh manure or organic matter eliminated 70–80% of re-sprouting. Spray application of ammonium sulfate delayed re-sprouting, but did not eliminate it. The use of manure and 'yard waste' can provide organic growers with a certified tool to control re-sprouting of decapitated trees.
