Abstract : Keitt Mango trees were sprayed with three materials kaolin, magnesium carbonate and calamine at three concentrations 3, 4 and 5% for each to prevent the injury of sunburn on fruits which causes economic losses. All Treatments were applied once during the summer of two seasons in this investigation and they were compared with the control (spraying water only) to study their effects on sunburned drop fruits percentage as well as yield and fruit quality. Results show that spraying kaolin or magnesium carbonate at 5% had a positive effect on reducing sunburned skin area and fruit drop percentage. This effect was clear detected with kaolin followed by magnesium carbonate under this experiment conditions.
