Abstract:A recent development in a dormant tree spray is described. The spray combines a type of oil emulsion and Flotation sulphur in such a manner as to give an efficient combination spray for San Jose scale and peach leaf curl. The methods of mixing and the physical properties of the combination are discussed.
