AB As part of an effort to develop biorational materials that can be easily incorporated into current nursery and landscape integrated pest management (IPM) strategies we evaluated two horticultural oils, a fatty acid based insecticide (insecticidal soap), sodium bicarbonate, an antitranspirant, and a conventional fungicide for the control of powdery mildew on field grown lilacs. In field trials both horticulturaloils (SunSpray Ultra-Fine and Saf-T-Side), performed as well as the standard fungicide (Bayleton). Horticultural oil combined with sodium bicarbonate in our trials was not significantly different from oil alone. Applications of sodium bicarbonate without oil failed to control powdery mildew and this treatment appeared similar to the control plants sprayed with water. The insecticidal soap (M-pede) was not significantly different from the horticultural oils in our evaluations. The antitranspirant (Cloud Cover) gave only slightly better results than the water treated plants.
