AB Scattered but persistent questions concerning the pesticidal efficacy and potential phytotoxicity of horticultural oils applied to woody and herbaceous plants in verdant condition prompted a continuing evaluation of the superior oil product Sunspray 6E. Fifty-one species commonly grown as ornamentals were evaluated for foliar phytotoxicity and efficacy against a wide range of arthropod pests. Treatment with 3% oil proved to be highly effective against aphid, scale, mite and other pest infestations. Phytotoxicity was limited to certain species of deciduous nut trees.
