Abstract
A comparison of liquid lime sulfur and a flotation sulfur paste on both young and mature apple trees indicates the marked superiority of the later material from several points of view. Lime sulfur resulted in a greater reduction of carbon dioxide assimilation, less stored starch, more visible leaf injury, less tree growth and a smaller yield. Flotation sulfur is a much safer material to use on apple trees than is lime sulfur. Laboratory results such as the gas analysis method of determining carbon dioxide assimilation, are supported by field data such as growth and yield records. From the standpoint of leaf injury, growth, and yield, flotation sulfur should be used in place of lime sulfur.
