“The efficacy of center pivot irrigation applications (chemigation) of chlorothalonil at recommended rates (1.25 kg a.i/ha) was less than with conventional, ground spray applications for control of late leaf spot (Cercosporidium personatum) in Florunner (susceptible) and Southern Runner (moderately resistant) peanut (Arachis hypogaea) cultivars in 1989 and 1990.”
