| dc.description.abstract | Plant extracts like upatlangra (Achyranthes aspera), kharazora (Teinostachynum
griaffithii), telakucha (Coccinea cordifolia), takamandir (Tinospora cordifolia) and
satodrone (Leucas aspera) were used against root-knot of chilli caused by
Meloidogyne sp. followed by seed treatment, soil drenching and seed treatment and
soil drenching method. Among the treatments, satodrone leaf 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 reduced population (L2, L3, L4 and adult female) of Meloidogyne sp. in
chilli in all methods. Better impact on plant growth characters as well as lower
galling incidence with reduced population of nematode was observed with
satodrone, takamandir, upatlangra, kharazora and telakucha leaf extract (S)
compared to control. Lower effect on plant growth character was found with
extract (S) of telakucha followed by kharazora, upatlangra, takamandir and
satodrone 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, L2,
L3, L4 as well as adult female under different treatments indicated the superior
effect of the treatments as evident with the lower galling incidence and the
suppressive growth of the nematode. All the extracts performed better in seed
treatment and soil drenching method than any other methods. | en_US |
