Abstract

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 severity (26.30%) 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 severity (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) 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 severity (20.34%) was recorded in neem cake precolonized with ThD + seedling dip in blitox (0.3%) treatment and also found highest fruit yield (24.97 kg).
