Table 2 Results of field trials evaluating disease control conducted in two vineyards in Sonoma and Colusa counties, 2005 and 2006. Values represent the least square means for percent infection of pruning wounds treated with four fungicides plus a water control and artificially inoculated with nine fungal pathogens. Results are presented as the average for the locations over both years. Values followed by a different letter in each row were significantly different according to Dunnett’s test (p = 0.05).
