dc.description.abstract Septoria ampelina causes a disease of grapes known as septoria leaf spot. This study was done to determined which of the fungicides currently used to control the various diseases of grapes, plus one experimental fungicide, is the most effective in controlling septoria leaf spot. Both in vitro and in vivo methods were used. In vivo studies examined the systemic and/or protectant activities of the fungicides. The systemic and protectant fungicides included Bayleton, Benlate, Elite (an experimental fungicide), Nova, Rovral and Rubigan. The protectant only fungicides included Captan, Dithane and Kocide. In vitro tests to determine the minimum inhibitory concentration (MIC) for each fungicide (e.g., the concentration of the fungicide that prevents the fungus from forming colonies on the PEA-fungicide medium), indicate that Benlate (MIC = 0.1 ppm) and Elite (MIC = 1.0 ppm) have the greatest potential'to control septoria leaf spot of grape. These are followed by Dithane, Nova and Rubigan (MIC = 2.0), which in turn are followed by Bayleton and Captan (MIC = 50.0 ppm). Kocide and Rovral did not inhibit fungal growth at concentrations up through 100 ppm. Although all the fungicides tested significantly reduced the incidence of septoria leaf spot in vivo, Benlate and Elite were the most effective fungicides (both in systemic and protectant application).
