In this study we aimed to reduce pomegranate losses because of sunlight injury in khorasan razavi province, Iran. Midday temperatures in summer may rise above 45◦C in this area causing sunburn damage to the fruits, which may object losses of up to 28% of the total yield. Processed kaolin (Khorasan Kaoline Co.) Sprayed over the whole canopy and fruits four times at 12 – 16 days intervals from early July to early September. All applications done at 6% of kaolin suspension. The resulting white coating significantly reduced fruit surface temperatures mean from 35.44◦C in control to 29.3◦C. Sunburn damage of fruits decreased from 22.35 % in control to 15.30 % in the kaolin treated fruits. Beside the total reduction in sunburn injury of fruits, kaolin reduced the severity of sunburn. Sunburned fruits in kaolin treated trees had lower intensity of injury in comparison to control, significantly
