The pedicel of golden marble is black.

Black spot disease is common in persimmon trees, and leaves, petioles, branchlets and pedicels can all be harmed, but it mainly harms leaves. There are two types of symptoms:

One is that reddish-brown to purple-brown spots appear on the surface of leaves at the beginning of the disease, and gradually expand into round or amorphous dark black spots. There is often a yellow halo around the spot, and the edge is radial, and the diameter of the spot is about 3-15 mm.

The second is the late stage of the disease spot, that is, the small black spots scattered on the pathogen meristem bubble disk. In severe cases, the lower leaves of the plant turn yellow and fall off early, resulting in the death of individual branches.

Prevention and control methods:

Spraying 50% carbendazim wettable powder 500- 1000 times, or 75% chlorothalonil 500 times, or 80% zineb 500 times, continuously spraying for 7- 10 days and continuously spraying for 3-4 times.
