Abstract
Description
Studies on the effect of AgNPs with five different concentration viz.,
0.0015 ppm, 0.003 ppm, 0.015 ppm, 0.03 ppm and 0.15 ppm on the mortality of M.
incognita showed that all the treatments with AgNPs were found to be effective in
causing mortality of M. incognita. The mortality of M. incognita increases with increase
in concentration and time of exposure. All the treatment were found to be effective in
causing mortality of Meloidogyne juveniles. Out of six treatments, the treatment with
0.15 ppm concentration were found to be the best treatment in causing maximum
mortality and the next best treatment was the treatment with 0.03 ppm concentration.
In the investigations, on the effect of AgNPs on the management of M.
incognita in green gram, the results showed that all the treatments were found to be
effective in increasing all growth parameters. Maximum growth parameter viz., plant
height, fresh and dry weight of shoot and root were recorded in the treatment with 0.15
ppm AgNPs + M. incognita. Maximum reduction in galls, eggmasses and final
nematode population in soil were recorded in the treatment with 0.15 ppm AgNPs. All
the treatments significantly differed from control except the treatment with 0.0015 ppm
AgNPs + M. incognita.
