Abstract:Home-made and central plant manufacture of the so-called, cold-mix, caseinate oil emulsion, during the past two years, and the indiscriminate use of this material have been the main causes for the suspicion and disfavor with which oil spraying in general is looked upon at present in the Northwest. Investigation has shown that the kind of emulsifier and method of emulsification of spray oil are practically as important as the oil itself, from the standpoint of safety and efficiency. The preparation of dependable oil sprays, therefore, involves technical ability, which can best be furnished by the insecticide chemist or specially trained entomologist. A highly refined, colorless oil emulsion has proven a safe and effective ovicide for the Codling Moth, Carpocapsa pomonella, and has been used successfully as a summer control for San Jose Scale, Aspidiotus perniciosus. The use of any dormant type of oil spray, even at low percentages, during the growing season is a dangerous practice. There is considerable evidence that oil sprays will soon return to favor in the Northwest.
