- Abstract
An experiment was conducted to study the role of different nanocides in the management of rice weevil and their impact on seed quality parameters at Seed Research and Technology Centre, Rajendranagar, Hyderabad, India. Nanocides viz, Nano silica, Nano alumina, and Nano clay, each at three different concentrations @ 500, 250 and 125 ppm/kg were compared with Diatomaceous earth @ 1000 ppm/kg seed and an untreated check. All 11 treatments were replicated thrice. The data on adult emergence, seed damage per cent, weight loss per cent, germination percentage and seedling vigour index were recorded at every three months intervals up to nine months of storage. Among the Nanocidal seed treatments, nano silica @ 500 and 250 ppm/kg seed was found to be superior as it gave complete protection to maize seed from development and seed damage caused by Sitophilus oryzae (Linnaeus) and also maintained germination (90.67 and 90.00%) above IMSCS > 90% upto nine months of storage as compared to control in which per cent seed damage at nine months of storage was 30.3% and also it maintained seed germination of 25% which is <IMSCS.
