Abstract:Since the insect pests of peaches are becoming increasingly important each year in Tennessee, a study of the newer spray materials such as cryolite and barium fluosilicate was made. These were compared with the standard lead arsenate. The latter material gave foliage injury at Kingston, Tennessee, whereas the fluorine compounds were found safe, when used at the rate of one pound to fifty gallons of water. The largest percentage of sound fruit, 81.11 per cent, was recorded for plot 7 receiving a dust of 50 per cent barium fluosilicate and 50 per cent sulphur. The plots sprayed with cryolite and barium fluosilicate showed 77.6 per cent sound fruit as compared with 68 per cent with lead arsenate and 5.8 per cent in the cheek plots. The fluorine sprays and dusts were decidedly more efficient than lead arsenate against the Oriental moth.
