Abstract:

Data are presented which indicate that the effectiveness of oil sprays is proportional to the heaviness of the oil and the percentage of oil used in the spray, and inversely proportional to the amount of spreader used in the spray. Within the range of sulfonation of the oils used in the tests, no significant difference in insecticidal efficiency of the sprays was caused by difference in sulfonation of the oils. Injury to foliage was found to be proportional to the heaviness of the oil and the percentage of oil used in the spray, and inversely proportional to the amount of spreader used and the sulfonation of the oil.
