Abstract
ABSTRACT. Vegetables are infected by
root knot nematodes, especially Meloidogyne
incognita, which results in both quantitative
and qualitative losses. This study’s objective
was to assess the effectiveness of plant
extracts from Senna alata and Tamarindus
indica in controlling cabbage-infecting root
knot nematodes. The experiment was carried
out to determine the effect of aqueous and
powdered extracts of T. indica and S. alata
on the control of root knot nematodes in two
cabbage varieties. The test plants underwent
phytochemical
screening.
Data
were
gathered on plant height, shoot weight, root
weight, yield and soil nematode populations.
All numerical data were subjected to
analysis of variance using the GENSTAT
statistical programme. Treating F1 Majesty
and F1 Minotaur with powdered T. indica
extract resulted in a significantly better
(p>0.05) growth and yield (62.77 cm and
53.77 cm) than the other treatments.
Significant variations were found between
the shoot, root and yield weights of treated
plants and their control counterparts. The
positive control had the highest number of
galled roots in both varieties (6.25 and 8.27).
The treated plants performed much better
than the control plants. The experiment also
revealed
some compounds, such as
hexadecanoic, butyric and octadecadienoic
acid. Based on this study’s findings, it is
advisable to make use of these botanicals (T.
indica and S. alata) on root knot-infested
farms, as they are cheap, available and eco
friendly
alternatives
to
chemical
nematicides, which are expensive and not
environmentally friendly.
