dc.description | Chilli (Capsicum frutescens) is one of the leading spices of Bangladesh,
where dry chilli contributes the major share. The chief use of chilli throughout the
world is due to its pungency and pleasant flavor. Capsicin, an alkaloid of chilli is
used in many pharmaceutical preparations like liniments and ointments for cold and
chest congestion like prickly heat powders and skin ointments (Pruthi, 1979). It helps
in the digestion of cereal foods. The nutritive value of dry chilli per 100 g of edible
portion are carbohydrate 30.6 g, protein 15 g, fat 6.2 g, mineral 6.1 g, fiber 30.9 g,
vitamin-C 50 mg and food energy-246 calories (Gopalan, ef al. 1981). It is available
throughout the country in all seasons but mostly grown in winter season. In 2002-
2003, the acreage of chilli was 144 thousand hectare and the production was 213.5
thousand mt (BBS, 2005). 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 climatic condition of Bangladesh
has made her an ideal abode for nematodes. The nematode population in the soil of
Bangladesh is increasing day by day (Chowdhury, 1976). | en_US |
dc.description.abstract | The standard (S) and half-standard (S/2) leaf extract of Bermuda grass, Water !
spinach, Ivy leaf morninglory, Nisinda, and Justicia were tested against root-knot of |
chilli caused by Meloidogyne javanica in two sets of pot experiment after 10 and 18 |
days of transplantation. Among the plant extracts, standard (S) extract of Bermuda |
grass followed by Water spinach gave superior result as it had increased shoot and
root length as well as fresh weight of shoot and root correspondingly with the lowest
galling incidence and development of adult female, J, J3, and Jy juveniles of
Meloidogyne javanica in chilli. Comparatively better effect on plant growth
characters with lower galling incidence and development of the nematode was
observed with standard (S) extract of Ivy leaf morninglory leaf followed by standard
(S) extract of Nisinda leaf. Half-standard (S/2) extract of Bermuda grass also gave
promising effect on plant growth characters with lower galling incidence and
development of the nematode. Comparatively lower effect of plant growth character
was found with half-standard (S/2) extract of Water spinach leaf followed by halfstandard (S/2) extract of Ivy leaf morninglory leaf. Half standard (S/2) extracts of
Nisinda and Justicia leaf were also found effective compared to control. Negative
correlations between gall numbers with shoot and root length as well as shoot and
root weight under different treatments indicated the superior effect of the treatment |
as envisaged with the lower galling and the suppressive activities of the nematode. | en_US |
