Abstract

The epidemiological effects of a protectant versus a systemic, sterol-inhibiting fungicide on disease components of Cercosporidium personatum were quantified by linear regression and/or probit analysis. The effects of chlorothalonil (a protectant fungicide) and tebuconazole (a systemic, sterol-inhibiting fungicide) were quantified for the following disease components: 1) infection frequency, 2) incubation period, 3) lesion size, and 4) sporulation. An inoculation technique to quantify the protectant versus systemic effects of fungicides on disease components was developed. Both fungicides greatly reduced spore germination when applied to peanut leaf surfaces prior to inoculation
