Laboratory tests with two per cent oil emulsions, under severe conditions, did not give the kill noted in the investigations of 1931.2 Several commercial oil emulsions have been used without injury on peach and apple. The same oils, in combination with sulphur, have been used on peach and in combination with 3-3-50 Bordeaux, on apple, without injury. Two per cent oil emulsions without lead arsenate gave no control of codling moth. A five per cent oil impregnated lead, sulphur, lime dust gave considerable reduction of oriental fruit moth injury.
