Synthesis of copper (II) citrate and evaluation ofits in vitro antifungaland antibacterial activities, and the suitability of using this chemicalas a plant protection agent

In this paper, copper (II) citrate Cu3(C6H5O7)2 was successfully synthesised in an aqueous solution. The factors for the synthesis process such as temperature and molar ratio of reactants were investigated. structural, properties composition characteristics elements investigated evaluated by X-ray diffraction pattern (XRD), Fourier-transform infrared spectroscopy (FTIR), energy-dispersive (EDX), UV-Vis spectroscopy. yield reaction 82.46% at CuSO4/C6H5Na3O7 1.5/1 70oC. vitro results showed that a concentration 1,000 ppm inhibits mycelial growth Sclerotium rolfsii Fusarium oxysporumwith control values ranging from 19 to 53% after 2 days incubation. Besides, it strongly suppressed plant bacterial pathogens Xanthomonas axonopodis (bacterial strain causing citrus canker), Ralstonia solanacearum(bacterial wilt tomato), Clavibacter michiganensis subsp. (cause canker tomato). These suggested can be used promising fungicide/bactericide fungal diseases on tomato plants.
