loquat disease identification
Hi, the loquat tree is located near to the downtown of Sacramento of California, planted for about 5 years. The disease showed up about 3 years ago. It first only affected a few fruits and leaves, but now it ruins about half of the fruits. It affected mostly the fruits, plus a few leaves. The branches and shoots are not affected. After the fruits are harvested, the tree looks normal. Three days ago we had the first 90F here, then the disease looked like suddenly appeared on the fruits. Does anyone know what it is and how to treat this disease? Many thanks!
