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)...
Citrus bacterial spot (CBS), caused by Xanthomonas campestris pv. citrumelo, produces unsightly blemishes on leaves and stems of nursery plants that may affect their mar ket value. In simulated nurseries, Swingle citrumelo and 'Ruby red' grapefruit infected with X. c. citrumelo were treated with combinations of defoliation and sprays of copper ammonium complex (CAC) to control CBS.
