| Show Now New Dusting Methods Tested in Michigan Charging Fungicides Ma May Revolutionize Spraying Fighting insects and plant diseases dis diseases eases which damage farm crops may be revolutionized by charging dust particles in fungicides and Insecticides In with electricity Michigan researchers reported recently Laboratory tests by Michigan State College researches show charging of dust particles of normal dusting compounds gets five to ten times better coverage than through usual dusting processes A A.
