The 1995 research project evaluated organic foliar amendments for disease control in tree fruits, grapes, and roses. Apple scab and powdery mildew were managed with fungicides and M-Pede, but M-Pede increased russeting, and handgun applications were more effective than mist blowers. In apples, Lime-Sulfur Solution and Ocean Fresh Fish reduced leaf scab but increased russeting, with lime sulfur causing injury. For sweet cherries, fungicides controlled brown rot blossom blight and leaf spot, while seaweed extracts showed promise for brown rot blossom blight in Royal Anne cherries, though Kocide DF caused phytotoxicity. Grape studies showed Thiolux DF treatments reduced powdery mildew in Cabernet Sauvignon, Chardonnay, and Venus varieties.

Peach trials indicated that fungicides reduced brown rot blossom blight and peach leaf curl, but preharvest treatments inadequately controlled brown rot fruit rot at harvest, although postharvest fruit rot was reduced. Pear rust was significantly reduced by most treatments except frozen Ocean Fresh Fish and Dithane M-45, and pear scab was controlled by fungicide treatments excluding Alliette, with Ocean Fresh Fish increasing russeting. In roses, most treatments significantly reduced powdery mildew, except for canopy pruning, but sodium bicarbonate caused phytotoxicity.
