Abstract
Root-knot nematode, Meloidogyne incognita is ubiquitous, polyphagous in
nature and causes severe losses in pulses including mungbean. Looking to its
economic importance, several pesticides have been tested for the management of rootknot
nematodes and found effective, but due to health hazards, residual toxicity,
environmental pollution and high cost, adoption of pesticides at farmers level has
been limited. Attempts were therefore, made to develop effective, economical and
eco-friendly technology for the management of root-knot nematode, M. incognita on
mungbean.
Biochemical studies showed that ascorbic acid @ 1000 ppm when applied as a
seed soaking + foliar spray proved most effective followed by ascorbic acid @ 500
ppm and salicylic acid @ 200 ppm with respect to plant growth parameters and to
reduced root-knot nematode infection on mungbean.
Mixed sowing studies revealed that mungbean when grown alongwith
marigold was found most effective in respect to plant growth parameters and to
decreased root-knot nematode infection on mungbean followed by mungbean +
sesamum and mungbean + clusterbean.
Organic amendment trial exhibited that neem leaves @ 12 g/plant was found
most effective with respect to plant growth parameters and to reduced nematode
reproduction on mungbean followed by neem leaves @ 8 g/plant and mustard leaves
@ 12 g/plant.
Integration of neem leaves @ 8 g/plant with ascorbic acid @ 500 ppm (seed
soaking + foliar spray) was found most effective with respect to plant growth
parameters and to reduced nematode infection on mungbean followed by mustard
leaves @ 8 g/plant + ascorbic acid @ 500 ppm and neem leaves @ 8 g/plant +
salicylic acid @ 100 ppm.
