Findings from University of Tehran Broaden Understanding of Plant Diseases (Synthesis of Nanopesticides by Encapsulating Pesticide Nanoparticles Using Functionalized Carbon Nanotubes and Application of New Nanocomposite for Plant Disease ...)

By a News Reporter-Staff News Editor at Life Science Weekly -- Data detailed on Plant Diseases have been presented. According to news reporting originating from Tehran, Iran, by NewsRx correspondents, research stated, "Polymerization of citric acid onto the surface of oxidized multiwall carbon nanotubes led to MWCNT-graft-poly(citric acid) (MWCNT-g-PCA) hybrid materials. Because of the presence of conjugated citric acid branches, synthesized MWCNT-g-PCA hybrid materials were not only soluble in water but also able to trap water-soluble chemical species and metal ions."

Our news editors obtained a quote from the research from the University of Tehran, "Trapping of pesticides such as zineb and mancozeb in aqueous solution by MWCNT-g-PCA hybrid materials led to encapsulated pesticide (EP) in the polycitric acid shell. Optimum conditions for encapsulation of zineb and mancozeb in hyperbranched polycitric acid such as pH, time of stirring, and temperature were investigated by the UV-vis spectroscopy method. Encapsulation of pesticides on CNT-g-PCA hybrid material was confirmed via TEM analysis."

According to the news editors, the research concluded: "Experiments indicated that new the CNT-g-PCA-EP hybrid material in comparison with bulk pesticide had a superior toxic influence on Alternaria alternata fungi."
