Abstract: Chilli, Capsicum annum L. is an annual herbaceous spice/vegetable/cash crop grown in both tropical and sub-tropical regions. Among the fungal diseases anthracnose or ripe fruit rot of chilli caused by Colletotrichum capsici (Syd.) Butler and Bisby is one of the limiting factors in cultivation of chilli. The survey revealed that the highest severity of anthracnose of chilli was recorded in Nalsvadi (46.35%). Plant extracts Ocimum sanctum, Neem Gold (300 ppm), Achook (1500 ppm) and Neem Fighter (10,000 ppm), T. harzianum, commercial bioagent Biocure F and Criyagen F, organic products Neem oil and Neem oil plus butter milk were found highly effective in inhibiting mycelial growth of C. capsici. Highest fungal population before planting and at flowering was noticed in Vermicompost (VC50%) + Farm yard manure (FYM50%) equivalent to recommended dose of nitrogen (RDN) with seedling dip in Panchgavya @ 3%, sulfur @0.2%, panchagavya @ 3%, nimbicidine (0.03% EC) @ 0.25% and VC 50% + FYM 50% equivalent to RDN with seedling dip in cow dung slurry @ 10% + Trichoderma harzianum @ 10g/l, sulfur @ 0.2%, nimbicidine (0.03%EC) @ 0.25%. The highest bacteria population before planting and at flowering was noticed in untreated check (VC50% + FYM50% equivalent to RDN) and VC50% + FYM50% equivalent to RDN with seedling dip in cow dung slurry @ 10g/l + Pseudomonas fluorescens @10g/l, sulfur @0.2%, nimbicidine(0.03%EC) @ 0.25%. Highest germination, seedling growth and vigour index was noticed in(VC50% + FYM50%) equivalent to RDN along with seedling dip in cow dung slurry @10% + Pseudomonas fluorescens 10g/l, sulfur @ 0.2%. The field trial results indicated that VC50% + FYM50% equivalent to RDN with seedling dip in cow dung slurry @10% + Pseudomonas fluorescens 10g/l, sulfur @ 0.2% recorded least per cent disease index and per cent infection in first and second picking and yielded(4.38q/ha).
