How to Tell If a Persimmon Tree Has Anthracnose? Detailed Explanation of Treatment and Prevention Methods

In the previous article, the editor discussed the characteristics and harm of persimmon tree anthracnose. So, how do you tell whether a persimmon tree has anthracnose? What are the control measures and prevention methods for persimmon tree anthracnose? Don't worry just yet; next, the editor will explain it in detail for you, focusing on the treatment and prevention methods for persimmon tree anthracnose. Let's take a look below~

I. How to tell whether a persimmon tree has anthracnose

1. Persimmon growers, if you find that in recent days your persimmon tree is not behaving normally, and the fruit, before it has even reached the ripening season, no longer stays properly on the tree and keeps falling off for no apparent reason, then pay attention: the persimmon tree may have caught anthracnose.

2. Carefully observe the leaves to see whether some small spots appear on them, white in color. Or whether the leaves have already become curled. If so, then your persimmon tree very likely has anthracnose.

II. Control measures for persimmon tree anthracnose

1. Be sure to remember: before the persimmon tree sprouts, spray once with 5-degree lime sulfur mixture, or spray lime sulfur mixture plus Bordeaux mixture.

2. Cut off the dried fruit and diseased branches on the persimmon tree branches, and take them far away to be burned in a centralized pile.

3. During the dormant period of the persimmon tree, chemical control methods need to be used. During the growth period in June, spray lime sulfur mixture plus Bordeaux mixture 2 times.

4. If it is a drought year, then the disease incidence is milder and easier to manage. The anthracnose pathogen reproduces best at around 25 degrees Celsius. Temperatures below 10 degrees or above 35 degrees are not suitable temperatures for its reproduction and spread.

5. Remember: persimmon fruit trees that are not carefully managed and are weak in growth are the most prone to the disease. So manage your persimmon tree well.

III. Prevention methods for anthracnose

1. Drainage prevention during the rainy season

When rainy weather brings waterlogging problems, first ensure smooth drainage; only in this way can the occurrence of disease be reduced and alleviated. In the rainy season, improve the supporting water system facilities; in the dry season with little rain, ensure timely irrigation when the soil is dry.

2. Improve the environment in the orchard

Improve the environment in the orchard, prune away excess dense branches and leaves, remove thin and weak branches, eradicate branches, leaves, and fruit infected by pests and diseases, and increase ventilation and air permeability in the orchard.

3. Reasonable fertilizer allocation

Apply more phosphorus and potassium fertilizer to strengthen the tree body. Applying other fertilizers will inevitably cause excessive vegetative growth of branches with insufficient tissue, which is unfavorable for disease resistance.

4. Winter cleanup must be thorough

In winter, a major cleanup of the persimmon orchard must be carried out, and the cleanup must be thorough. Remove bacteria in the orchard, prune diseased branches and diseased dried fruit, and trim excess branches. Isolate all possible sources of infection.
