The advantage gained bythis combination is that we can spray against both fungiand insects in one operation. If desired, in place of thearsenate of lead, from 4 to 8 ounces of Paris greenmay be used. Less of the Paris green than of thearsenate of lead is used because the Paris green hasa tendency to injure foliage. In spraying peach trees,and other plants having tender foliage, Bordeaux mix-ture and lead arsenate, the 2-2-2-50 mixture should belUsed, and never should Paris green
