Endophytic isolates of Trichoderma viride and T. pseudokoningii from black pepper caused 64.4 and 65.6 per cent inhibition of mycelial growth of Phytophthora capsici in vitro. In planta screening showed that the isolate of T. viride was efficient in reducing Phytophthora rot incidence and enhancing plant growth characters. In pot and field experiments also this isolate resulted in the lowest infection by the pathogen.Keywords

Bacterial wilt is one of the most dreaded diseases in tomato growing areas all over the world. Though chemical control measures and resistance breeding offers certain degree of protection against wilt pathogen, both have their own limitations such as high cost, environmental impact, non target effect and development of resistance. Hence, biologically safe methods such as use of composts as soil amendments for wilt management was investigated in the present study which revealed the possibility of the use of ligno-phenolic composts in disease management. Among the five composts tested, application of ayurvedic compost at 45 days after planting was found to be the most effective with lowest wilt incidence of 6.94 per cent against 36.10 per cent in control, with 80.77 per cent disease reduction. At 60 DAP, same trend was noticed with minimum disease incidence in ayurvedic compost (13.88 %) which was on par with full basal application of leaf litter compost (15.27 %), and coir pith compost (16.66 %) with 86.79 to 60.02 per cent reduction of wilt incidence. In case of yield, among the different composts, split and basal application of ayurvedic compost recorded highest yield of 8.9 kg/6.48 m2.Keywords

A study was undertaken to determine the presence of aflatoxigenic fungi and other fungal contaminants in the kernel, mace and shell of ripened nutmeg tree fruits collected from nutmeg plots of Ernakulam and Thrissur districts of Kerala. Mace and nut were separated from fruits and washed in tap water to remove soil particles and other debris adhering to it. The kernel, mace and shell were subjected to different chemical/botanicals by four methods viz; dipping, decoction, samples in cloth bag and fumigation in order to prevent aflatoxigenic fungi and other fungal growth during storage. Based on the present studies, it was found that pre-treatment of kernel, mace and shell of nutmeg with either citrus leaf decoction (@100 g/litre) or curry leaf decoction (@ 100 g/litre) or Anona seed extract (5%) using decoction method were effective against aflatoxigenic fungi as well as fungal contamination. However, further studies are needed on pilot scale to confirm.Keywords
