Jujube Anthracnose Prevention and Control Measures
In the middle of August and September of each year, the weather is hot and rainy, and jujube anthracnose is at a high stage. Bacteria are transmitted through dew and wind and rain. The onset of disease is sooner or later related to rain. If rain is more frequent in June, the disease usually begins in late June. In dry years, the disease is light or does not occur. After the disease, the diseased part or the jujube's waist is the most vulnerable. It initially turns light yellow, and then there are water-stained spots. It gradually expands into irregular yellow-brown patches, with round depressions in the middle, and the diseased patches are red-brown. Cause the fruit to fall early, so jujube anthracnose should be prevented as soon as possible. Preventive measures: (1) Strengthen the comprehensive management of the jujube garden to increase the organic fertilizer, and use the new high-fat membrane to prevent insects and protect the plants. (3) A reasonable intercropping between the Zaoyuan for peanuts, sweet potatoes and other low stalk crops, reduce the park's air humidity, reduce the incidence of disease. (4) Use the general of the Hushu Tree to sterilize the Qingyuan Garden, trim the jujube hangings, diseased shoots and dead branches left on the tree, and deep-dip in winter to clear the pathogen. Above for reference.
