Abstract:
A survey was conducted in selected ginger growing areas of malnad districts of Karnataka to know the incidence of rhizome rot complex disease in ginger. Among the different places where survey was conducted, Banavasi in Uttar Kannada district recorded the highest incidence of disease 40-48 PDI and the least incidence(15-18 PDI) was recorded in Haveri district Among the different treatments, T9 (Pre-sowing soil application with Trichoderma harzianum enriched FYM (@ 2 kg/ton) + Pseudomonas fluorescens enriched FYM (@ 5 kg/ton) + Neem cake (1.0 qt/ac.) + Pre-sowing rhizome treatment with 0.05% Streptocycline + 0.30% Copper oxy-chloride for 15 minutes followed by drenching with 0.30% Bleaching powder + 0.30% Copper oxy chloride + 0.15% Metalaxyl-MZ + 0.05% Streptocycline) recorded the least Per cent Disease Incidence (4.25) and the highest rhizome yield (370.83 Q/ha). The highest phenol content (3.622 and 4.117 mg/g leaf tissue), reducing sugars (4.976 and 2.954 mg/g of leaf tissue), non-reducing sugars (1.862 and 0.957 mg/g leaf tissue) at 60 and 90 Days after planting in inoculated plants recorded in CV. Himachal. Whereas, the highest chlorophyll content was recorded in Cv. Varada (39.46 and 31.94) at 60 and 90 days after planting.
