Description 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).
