Integrated management strategies for red rot disease of sugarcane

Abstract

Field experiments were conducted during 2006–07 and 2007–08 crop seasons at IISR institute farm, Lucknow to find out the impact of Integrated Disease Management (IDM) practices over Non-Integrated Disease Management (NIDM) i.e. normal package of practices of cane cultivation on red rot incidence, yield and quality parameters of sugarcane in plant and ratoon crops of moderately susceptible variety CoSe 92423. It was observed that in both plant and ratoon, IDM practices reduced red rot incidence, enhanced growth parameters and quality attributes of sugarcane compared to NIDM practices. In plant crop of IDM practices, germination was improved by 6.29%, tiller counts (16.93%); millable canes (4.90%); yield (13.09%); juice extraction (2.33%); pol % juice (0.46%); purity (0.88%), CCS (16.47%), plant height (8.90%), cane girth (13.52%); internodes (12.67%); internodal length (3.00%) and cane weight (34.04%) over NIDM practices. In ratoon crop, improvement in clump emergence (30.0%), height of cane (14.76%), cane girth (7.66%), internodes (5.31%); internodal length (14.04%); cane weight (18.90%); juice extraction (5.56%); pol % juice (0.84%); purity (2.12%), CCS t/ha (22.42%), tiller counts (19.77%), millable canes (12.09%) and yield (18.38%) was observed in IDM over NIDM practices. Thus, this study revealed that use of T. viride is beneficial for controlling red rot, improving quality attributes, enhancing yield and shelf life of a moderately red rot susceptible variety.
