Tea cake disease harms tea tree growth
Tea cake disease, also known as blister leaf blight and leaf swelling disease, is an important disease on tender shoots and leaves, distributed in various tea areas throughout the country, mainly damaging tender leaves, tender stems, new shoots, buds, fruits and petioles. Young leaves infected with the disease initially appear pale yellow to reddish brown translucent small spots, and then expand into a circular spot with a diameter of 0.3~ 1.25 cm. The front of the spot is depressed, light brown to dark red, and the back is raised. It is a steamed bun shaped blister with gray or pink or gray powder on it. The powder disappears in the later stage, and the raised part shrinks to form brown withered spots. There is a round spot around the edge.
