| dc.description.abstract | Chilli and brinjal are important spice and vegetable crops in India and known to be suffered mainly by Colletotrichum capsici and Phomopsis vexans respectively. These pathogens cause damping off at seedling stage and fruit rot at maturity stage affecting the crop yield and marketability of the produce. Seed treatment with carbendazim or other chemical fungicides for control of these important diseases are already in vogue. However, use of these chemicals lead to residual toxicity, induced resistance to pathogens and environmental pollution. Hence, an attempt was made to identify eco-friendly natural measures like plant oils or biofungicides in place of carbendazim to control these diseases. Results revealed that the mycoflora including Colletotrichum capsici and Phomopsis vexans were controlled with the use of carbendazim (2 g kg-1 seed) and also equally with the neem oil treatment @ 5 ml kg-1 seed or Trichoderma viride @10 g kg-1 seed. Further, seedling parameters like seed germination, seedling growth, seedling vigour and disease control were high in infected seed treated with plant oils or biofungicides and were comparable to that of carbendazim treatment. Among the plant oils, neem oil was relatively better than carbendazim in controlling disease and improving the seedling parameters. Similarly, among the biofungicides, Trichoderma viride was better over the Trichoderma asperellum, Pseudomonas fluorescens and their combinations to control the disease and to enhance the seedling vigour. Hence, seed treatment with neem oil @ 5 ml kg-1 seed or Trichoderma viride @10 g kg-1 seed can be effectively used in place of carbendazim (2 g kg-1 seed) for chilli and brinjal to control diseases and also to achieve higher seedling vigour which leads to higher crop productivity. | en_US |
