abstract
Evaluation of new pesticide for the management of Sitophilus granaries was carried out in Nano – Bio translational research Laboratory, Bannari Amman Institute of Technology, Sathyamangalam during 2017-2018. An attempt was made to control the Sitophilus granaries menace by organic modus in combination with nanotechnology. The aqueous extract of Anthocephalous cadamba was used as reducing and capping agent for the phyto synthesis of iron oxide nanoparticles. The incorporation of nanotechnology enhanced the target specificity and mortality rate of pests. The antimicrobial activity of phyto synthesized iron oxide nanoparticles (PION) against Bacillus sp., (Gram +ve) and E. coli (Gram –ve) exhibited the minimal zone of clearance less than chemically synthesized iron oxide nano particles (CION), which implies that the PION is specifically lethal only to the pest. Out of the three, PION exhibited 100% mortality against Sitophilus granarius. Hence the iron oxide nano particle in conjugation with the aqueous extract of Anthocephalous cadamba has proved to be a target specific effective pesticide.
