abstract
An experiment was conducted to study the effect of different nano particles, viz, Nano silica @ 0.5g kg-1, 0.25g kg-1, 0.175g kg-1 of cured turmeric rhizomes, Nano alumina @ 0.5g kg-1, 0.25g kg-1,0.175g kg-1 of cured turmeric rhizomes, Nano clay @ 0.5g kg-1, 0.25g kg-1, 0.175g kg-1 of cured turmeric rhizomes and Diatomaceous earth @ 5g kg-1 of cured turmeric rhizomes (check) along with control. All the treatments were replicated thrice. Among the three nanocides, nano silica applied at 0.5 and 0.25 g kg^-1 dosages showed the superior performance of the over other treatments at one day after treatment followed by nano silica at 0.175 g kg^-1 which caused higher mortality, reduced oviposition and adult emergence of L. serricorne and has a great promise in cigarette beetle pest management.
