First, how to judge whether persimmon is suffering from anthracnose

1. For the vast number of persimmon growers, if you find that there is something wrong with your persimmon tree these days, the fruit will not stay on the tree well before the fruit is ripe, and it will always fall down for no reason. Then you should pay attention to it. Maybe the persimmon tree is suffering from anthracnose.

2, carefully observe the leaves to see if there are some small spots on the leaves, the color is white. Or the leaves are already in a curly state. If so, it is very likely that your persimmon tree has anthracnose.

Second, the prevention and control measures of persimmon anthracnose.

1. Be sure to remember that before the persimmon sprouts, spray it with a 5-degree stone-sulfur mixture, or spray stone-sulfur mixture plus Shi Baomei.

2. Cut off the dried fruit and diseased branches from the branches of persimmon trees, take them far away and burn them centrally.

3. Chemical control method should be adopted during the dormant period of persimmon trees. During the growing season in June, spray stone sulfur mixture and Shi Baomei twice.

4. If it is a dry year, the disease is light and easy to manage. The reproduction of anthrax is the most suitable at about 25 degrees Celsius. Temperatures below 10 degrees and above 35 degrees are not suitable for breeding and spreading.

Remember, persimmon trees with poor management and weak growth are most likely to suffer from the disease. So manage your persimmon tree.

III. Measures for prevention of anthrax

1. Dredging and prevention in rainy season

When there is a problem of stagnant water on rainy days, we must first ensure the smooth flow of drainage, so as to reduce the occurrence of diseases. Improve the supporting facilities of the water system in the rainy season, and ensure the dry and timely irrigation in the dry season.

2. Improve the environment in the park.

Improve the environment of the garden, cut off the extra dense branches and leaves, get rid of the thin and weak branches, eradicate the branches and fruits infected with diseases and insect pests, and increase the ventilation and permeability of the garden.

3. Rational distribution of fertilization.

Apply more phosphorus and potassium fertilizer to strengthen the tree body. The application of other fertilizers will inevitably lead to the phenomenon of unsubstantial branches, which is not conducive to disease resistance.

4. Clean up thoroughly in winter

In winter, persimmon orchards should be cleaned up thoroughly. Remove bacteria in the garden, cut off diseased branches, diseased dried fruit, and prune excess branches. Isolate all infectious bacteria sources.
