Abstract
Curaterr solution(0.2%), standard extracts of Bashak leaf (Adhatoda vasica),
Pineapple (Ananas sp.) and Mustard oil-cake (Brassica campestris) were tested
against root-knot of Brinjal caused by Meloidogyne javanica . Among the treatments,
Curaterr solution(0.2%), gave the highest response followed by Bashak leaf extract in
plant growth like shoot length, root length, shoot weight, root weight, yield characters
like fruit number and fruit weight consequently with the suppressed development of
gall. Mustard oil cake extract resulted higher response in increasing plant growth than
Pineapple extract. Negative correlations observed between galling incidence with
shoot length, root length, shoot weight, root weight, fruit number and fruit weight of
Brinjal indicated the better action of Curaterr and plant extracts on the suppression of
the nematode activity.
Description
In Bangladesh Brinjal (Solanum melongona) is a popular, cheap and easily
