dc.description | Chilli (Capsicum frutescens) is one of the most popular and leading spices in
Bangladesh with world wide distribution. In Bangladesh 87,044.53 hectares land
is under its cultivation and total production is 1,09,000 t. per annum
approximately (BBS, 2009-10). Capsicin, an alkaloid of chilli is used in many
pharmaceutical preparations like lineaments and ointments for cold and chest
congestion like prickly heat powders and skin ointments. It helps in the digestion
of cereal foods (Pruthi, 1979). The nutritive value of chilli is high as it contains
1.29 mg protein, 11 mg calcium, 870 1. U. vitamin-A, 17.5 mg ascorbic acid, 0.06
mg thiamine and 0.03 mg riboflavin and 0.55 mg niacin per 1.008g edible fruit
(Joshi and Singh, 1975). On a global basis, out of the approximately 35 % crop
losses annually caused by crop enemies; 12 % is due to diseases caused by fungi,
bacteria and viruses, 11 % is due to diseases caused by nematodes, 7 % is due to
insects and 3 % is due to weeds (Cramer,1967). According to Sasser and
Freckman (1987), the annual loss of crops due to nematode is about 12.3 %. Loss
in chilli due to nematode is 12.2 % (Singh, 2005). The soil and climate of
Bangladesh are very favourable for the cultivation of chilli, but the crop
cultivation is hampered by the attack of several species of nematodes (Timm and
Ameen, 1960). Moreover, the nematode population in the soil of Bangladesh is
increasing day by day (Chowdhury, 1976). Plant parasitic nematodes, especially,
root-knot nematodes are associated with many solanaceous crops especially with
chilli (Anwar, 1977 and Qumar et a/., 1985). The soil and climatic condition of
Bangladesh has made her an ideal abode for nematodes. It is reported that 15
genera of plant parasitic nematodes are associated with commercial crops in
Bangladesh, where Meloidogyne spp. are more abundant and widespread (Timm
and Ameen, 1960). Among the different diseases caused by nematodes, the rootknot caused by Meloidogyne spp. | en_US |
dc.description.abstract | Seven treatments viz. BAU-Biofungicide (Trichoderma spp.), mustard (Brassica —
campestris) oil-cake, basak (Adhatoda vasica), telakucha (Coccinia indica),
takamondir (Tinospora cordifolia) and satodron (Leucas aspera) extracts in
standard concentration with a control were tested against root-knot of chilli
caused by Meloidogyne javanica through root dipping and soil drenching methods
(after 7 and 21 days of transplantation). Among the treatments, BAUBiofungicide and mustard oil-cake extract (S) gave superior result as it had
increased length of shoot and root, weight of shoot and root, number of fruit and
weight of fruit per plant with the lowest galling incidence as well as the reduced
population of Lz, L3, L4 and adult female of Meloidogyne javanica in chilli in all
methods. Better effect on plant growth characters with lower galling incidence
and development of the nematode was observed with basak, satodron, takamondir
and telakucha extract (S) compared to the control. Lower effect on plant growth
character was found with extract (S) of basak followed by satodron, takamondir
and telakucha leaf extract (S). Negative correlations between number of galls with
length of shoot and root, weight of shoot and root and number of fruit and weight
of fruit and positive correlations between number of galls with egg, eggmass, Lo,
L3, L4 as well as adult female under different treatments indicated the superior
effect of the treatments as envisaged with the lower galling incidence and the
suppressive activities of the nematode. | en_US |
