Abstract
In field experiments conducted during 1990 and 1991, chemigation applications of biosynthesis inhibiting fungicide cyproconazole (0.112 kg a.i./ha) were equal to or bether than ground-spray applications of cyproconazole or chlorothalonil (1.26 kg a.i./ha) late leaf spot, caused by Cercosporidium personatum, on peanut (Arachis hypogae) cultivars Florunner and Southern Runner. Late-season leaf spot epidemics and resulting defoliation were severe in nontreated plots in both years. All fungicide treatments provided similar levels of control in 1990 (.)
