Resumo:  In 2002 and 2003 two randomized trials and three “on farm” trials where carried out to test the hypothesis that a single winter treatment could reduce the primary inoculum of Sooty Blotch sufficiently to prevent fruit disease during summer. copperoxychloride (0.2%-0.4%) and lime sulfur (4.0%-5.0%) were applied until run-off in March shortly before bud break. Assessments of Sooty Blotch incidence and severity where made immediately after harvest. The winter treatments with copperoxychloride did reduce disease severity during summer in one case. The treatments with lime sulfur reduced the disease level in three sites to some extent. However, winter treatments alone were not nearly as efficient as summer treatments. Therefore, we see no reason to advise this kind of treatment with lime sulfur in practice as the effectiveness is poor, the necessary spray cover can not be reached under practical conditions, and with the amount of material needed for this single spray five sprays can be made in summer that will be more effective to control the disease.
