In Turpan region of Xinjiang, with the continuous cultivation of vegetable growing area in the greenhouse, continuous cultivation of the main varieties of pepper in the greenhouses and the increasing resistance of the pathogenic bacteria in the greenhouse resulted in serious deterioration of peppers diseases. Some vegetable farmers were eager to cure diseases and pesticides frequently, Concentration spraying or spraying mixed with several pesticides, the drug particles directly block leaf stomata, water holes, so that photosynthetic plants, transpiration and respiration blocked, which showed a series of physiological diseases and tissue lesions occurred phytotoxicity. In the event of injury, the leaves hardest hit, the general performance of the leaves withered, color reduction, gradually become yellow-white, and accompanied by various colors
