Control of leaf blight of Platycladus orientalis

Platycladus orientalis leaf blight: the bacteria spent the winter on the diseased leaves and began to move in April of the following year. In May, the diseased leaves began to infect from the lower part of the crown, and the diseased leaves appeared macula at the initial stage, which gradually expanded, making the whole cypress leaves yellow and finally yellowish brown. In June, black spots appeared on the diseased leaves, that is, the reproductive organs of the bacteria, and released spores for re-transmission. If the forest is dense, the humidity in the forest is high, and the temperature is suitable, it will spread and infect in large numbers, resulting in a pandemic of the disease, with the most serious disease from June to July. There is often a disease center in the dense forest, which gradually spreads out into a piece, and when it is serious, it looks like a fire, and a large number of diseased leaves fall off, often sprouting clumps of new leaves from the branches of the tree trunk, and people call it "tree beard."

Prevention and control methods:

1. Clean the diseased leaves under the tree in autumn and winter, burn and dye the source. Eliminate the pathogen of winter and reduce the first invasion

2. From May to August, spray Bordeaux solution with Bordeaux liquid once every two weeks, especially pay attention to strictly control the primary infection, find the center of primary infection, block it and prevent it from spreading.

3. The over-dense cypress forest should be thinned properly to make the forest ventilated and transparent and reduce the disease conditions.
