Polymerization of citric acid onto the surface of oxidized multi wall carbon nanotubes was led to MWCNT-graft-poly (citric acid) (MWCNT-g-PCA) hybrid materials. Trapping of pesticides such as Benomyl, Trichlorfon and Pymetrozine (chess) in aqueous solution by MWCNT-g-PCA hybrid materials was led to Encapsulated Pesticide (EP) into polycitric acid shell.Optimum condition for encapsulation of Benomyl, Trichlorfon and Pymetrozine in hyper branch polycitric acid such as pH, stirring time and temperature was investigated by UV-Vis spectroscopy method. Also encapsulations of pesticides on CNT-g-PCA hybrid material were confirmed via TEM analysis. Furthermore effect of encapsulated Benomyl on Alternaria alternate fungi was investigated. Experiments indicated that encapsuled Benomyl in comparison with bulk Benomyl had superior toxic influence on Alternaria alternata fungi.
