Development of a fungicide spray schedule to determine the effect of sugarcane rust (Puccinia melanocephala) on yield

Abstract

This study reports on work carried out to develop a fungicide spray program which is suitable for yield loss assessment investigations. Aspects examined include the efficacy of various concentrations of chlorothalonil and oxycarboxin on rust, the frequency of application of one concentration of chlorothalonil or oxycarboxin on level of infection, and arrangement of spray nozzles to give good coverage of fungicides.
