Wilt in brinjal has become more damaging in the red lateritic soil of Jharkhand due to the prevalence of Fusarium oxysporum and Ralstonia solanacearum making it wilt complex disease. Out of six organic amendments tested soil application of neem cake (5q/ha) proved to be the most effective treatment to minimize wilt incidence (26.3%) and increased fruit yield (19.23 kg/plot). Among the five fungicides viz; carbendazim, mancozeb, tricyclazole, blitox, oxathiin and streptocycline, seedling dip with mancozeb (2.5g/l) was most effective and showed least wilt incidence (24.21%) with highest fruit yield (21.59 kg/ plot) which was significantly at par with blitox-50. Among four bioagents viz; Trichoderma viride (TvD) Delhi isolate, Trichoderma harzianum Ranchi isolate(ThR), Trichoderma harzianum (ThD) Delhi isolate and Pseudomonas fluorescens Delhi (PfD) isolate soil application of precolonized ThD proved to be most effective in reducing wilt severity (16.15%) and highest fruit yield (24.79 kg/plot)were recorded. In the integrated approach of chemicals with bioagents and organic amendments under field condition among all the combinations, minimum wilt incidence (20.34%) was recorded in neem cake precolonized with ThD + seedling dip in copper oxychloride (0.3%). This treatment also provided the highest fruit yield (24.97 kg).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
