What about the leaf blight of the rich tree: what about the long spots on the leaves of the rich tree: the leaf spot is easy to distinguish, and dark brown or brown spots grow on the leaves at the beginning.

Make a fortune tree, this is a lot of people are super like, this name is not super auspicious, to see how to make a fortune tree with long leaf spots? What about the leaf blight of the rich tree:

What if the rich tree has long spots on its leaves:

Leaf spot disease is easy to distinguish. At the beginning, dark brown or brown spots grow on the leaves, especially on the outer edge of the spots, which are particularly dark, while the inside of the leaves will slowly become gray and white, feeling like being exposed to the hot sun. If the disease is aggravated, these irregular spots will slowly expand, continue to infect other plants, and black powder will appear on the spots.

Introduction of prevention and control methods:

1, the prevention method is very simple, that is, in rainy or wet season, spray carbendazim or topiramate once a month, to avoid spraying directly on the leaves, there will be white stains.

2. Of course, the diseased leaf disease branches should be cut off first to avoid further infection, and the scissors built should be sterilized before use to avoid secondary infection.

3. If a serious disease spot has been induced, carbendazim can not be used, and the effect is not great. After cleaning the diseased leaves, use chlorothalonil or thiophanate spray. It can also be used in combination with methyl topiramate. The effect of alternative use is better.

4. It is necessary to improve the conservation environment, strengthen ventilation, reduce watering, avoid the environment from being too closed, and the lack of nutrients in the soil is also easy to infect diseases and insect pests. Organic liquid fertilizer can be given once or twice a month after recovery to ensure the growth of the plant and avoid the next infection.

The solution to the leaf blight of rich trees:

Leaf blight is very different from leaf spot, and it is easy to distinguish. Leaf blight is that the whole leaf is scorched black or brown, while leaf spot is black on the outside and white on the inside. The leaf blight begins with brown spots and spreads slowly into a large brown or scorched black patch.

If the leaf blight is not dealt with in time, it will spread slowly, and the disease will be aggravated when it is wet, which should be solved in a timely manner.

Treatment method:

1. The diseased leaf disease branches can be cut off in the early stage of the disease to improve ventilation and light transmission.

2. At the initial stage of the disease, Acetobacter or thiophanate-methyl can be sprayed, and the solution can be prepared according to the proportion of the instructions, or alternately used with copper sulfate suspension and daconine. The effect is the best, usually once every 7 days, about 4 times in a row.

When dealing with the diseased leaves of the rich tree, we should pay attention to distinguish what the disease is, so that we can solve the problem as soon as possible and help the rich tree restore its healthy state as soon as possible.

This is the end of the treatment of leaf blight and long leaf spots of the rich tree, so that the rich tree can be cultivated well.

Rich tree leaves have brown spots, pay attention to distinguish leaf blight from leaf spot.

Brown spots appear in the leaves of the rich tree, which will not only affect the appearance of the rich tree, but also very likely affect the growth of the rich tree. However, brown spots alone may not be able to accurately judge what is wrong with the rich tree. This paper intends to introduce the brown spot on the leaves of the rich tree, and briefly introduces the two diseases of the rich tree and their control methods.

Leaf blight and leaf spot are common diseases of rich trees.

1. Leaf blight

Disease symptoms

The initial production of dark brown, the internal production of gray or dark brown symptoms like sunburn spots, long-term lesions can be seen on the black powder.

Prevention and cure method

1. Diseased leaves should be removed and destroyed in time.

2, strengthen maintenance and management, timely watering, fertilization, each growing season can be topdressing 2 to 3 times foliar fertilizer, such as 0.5% potassium dihydrogen phosphate or double-effect micro-fertilizer 200 times.

3. Prevention. When rich trees are cultivated in the southern region, timely prevention should be carried out from the rainy season, spraying 50% carbendazim 800x solution, or 70% chlorothalonil 800x solution, 75% methyl thiophanate 1500 times solution every 10-15 days.

4. At the initial stage of the disease, spray control with 75% chlorothalonil wettable powder, or 50% carbendazim wettable powder, or 1500 times methyl thiophanate wettable powder.

2. Leaf spot

Disease symptoms

The disease causes leaf scorch and is an important leaf disease. The disease affects growth and appreciation. In the early stage of the disease, small brown spots appeared on the leaf edge or leaf tip, and after expansion, the disease spot was irregular and dark brown; in the later stage, the disease spot was gray or grayish brown, the edge was dark brown lines, and there were or no yellow lesions in the periphery of the disease spot. The major disease spot is in the shape of paper. Under wet conditions, the disease produces a small number of small black spots.

Treatment method

At the initial stage of the disease, the new high-fat membrane was sprayed with 65% Acetobacter wettable powder or 50% methyl thiophanate, 800 times sulfur suspension, 30% basic copper sulfate suspension 400 times, 75% Dakening wettable powder 700 times, and so on. Once every 10 days.

Whether it is leaf blight or leaf spot, brown spots will appear on the leaves. Therefore, the rich tree leaves have brown spots, before prevention and control, we need to distinguish between different diseases in order to prescribe the right medicine to cure the disease.

What if the leaves of the rich tree always grow leaves?

Bonsai Flower Network Guide: today, the editor of the Flower Bonsai Network shares an article about how the leaves of rich trees always grow. Let's take a look.

The disease spot of the rich tree is caused by improper maintenance, and it is generally caused by fungal infection caused by too much watering, too strong light or too low temperature, which will not only cause long spots on the leaves, but also cause the whole plant to wilt seriously. So how to solve the problem of long spots on the leaves of the rich tree?

Tips:

To improve the conservation environment is the most critical, potted rich trees to avoid frequent watering, it is easy to rot roots or induce diseases and insect pests. Be careful not to pour tea or coffee grounds into the basin, it is easy to burn plant roots, but also easy to breed diseases and insects, let alone bury unripe rice water, milk or bean dregs into the basin soil.

First, get rich leaf blight

Leaf spot disease is easy to distinguish.
