First Paragraph: Hopefully the coming season does not have the weather related problems experienced by growers in the 1998 season. One problem especially noted is the extensive damage caused by Phomopsis Cane and leaf spot on highly susceptible varieties such as Thompson seedless, Grenache, Tokay, Flame, and Red Globe. Below are the results of the experimental trial conducted by Paul Verdegaal (San Joaquin County Viticulture Advisor) and myself in Manteca on Grenache. UTC was the untreated control to provide the level of disease without any treatments. All rates are formulated material per acre except treatment 2 which was applied at 3.2 oz per gal. of water.
