How to treat the rust spot of fir leaf (cause and medication)

First, the reasons:

The rust spot of banyan is easy to occur under the condition of high temperature and humidity, especially from March to June and October to November in Guangzhou and other places. At the same time, some diseases can also spend the winter with plants. The second year will be active and continue to harm its leaves.

Second, to deal with:

1. If the erosion of the leaves is more serious, it is recommended to cut off the leaves directly.

2. If the whole plant is relatively infected by the disease, the disease site can be removed first, and then the basin and soil can be changed.

3. Special medicine can also be used for spraying, if it is not serious, it can only be sprayed with medicine, and in serious cases, consideration should be given to changing the basin and soil.

4. Do not spray water to the leaves after rust spots appear.

Control methods of banyan banyan blight rot

1. Cultivation and management

Strengthening the management of cultivation is beneficial to enhance the disease resistance of the plant and make it healthier. The soil had better choose loose and permeable sandy soil with good drainage performance, give sufficient light, appropriate shade in summer to avoid direct sunlight, winter temperature had better not be lower than 10 ℃, in order to prevent frostbite leaving scourge, watering not too much, long-term humid environment will not bring too many benefits. Usually pay more attention to clean up the dust on the leaves, whether it is thin or heavy, should be disposed of in time to keep the leaves dry.

2. Get rid of dead plants.

After the disease, the plant should be moved to a sunny and well-ventilated place in time, do not sprinkle water on the leaves, and cut off the diseased leaves. When cutting off diseased leaves, cut off the spotted part and part of the healthy tissue, and then spray some Dodor solution to protect it, or you can spray some doubling solution, such as 80% Dysen zinc wettable powder 500 times, 25% metalaxyl wettable powder 500-800 times, and so on.

Why did the banyan lose its leaves?

Generally speaking, it is not a particularly strange thing for a plant to lose its leaves, but what we need to think clearly is that the loss of leaves is different. Qin Yerong is an evergreen plant all the year round, with luxuriant flowers and no leaves. Isn't that equivalent to the attending doctor without a scalpel? it's a little scary to think about it. The reason why Qin leaf banyan loses leaves is undoubtedly due to the insufficient supply of yin and yang. There are too few nutrients in the soil. In addition, insufficient water supply or too much water supply will cause banyan leaves to lose their leaves. Insufficient nutrients have the same effect on banyan leaves as insufficient water supply, that is, they make the leaves withered and yellow, while too much water supply will make the leaves look green, but they are easy to fall when touched.

When does the leaf banyan change the basin?

1. Time

Changing the basin does not need to be done every year, usually we do it every two or three years, and this operation needs to be done in the spring. Only at this time can it be in line with its growth, and changing the basin will be more successful.

2. Soil

If you change the basin, consider the soil it needs, which it likes is loose, but also needs strong drainage, generally speaking, peat soil or some acid soil is feasible. In addition, we'd better give it mixed rotten leaf soil or culture soil and coarse sand, etc., if we can add some basic fertilizer, so much the better.

3. Flowerpot

Its flowerpot is not a random choice, generally speaking, the first thing we have to determine is its size, not too large, if too large impact on it is not good. If the plant itself is relatively small, the diameter we choose for it is between 20 and 25. If it is larger, we have to choose about 30 to 35 for it. In addition, the bottom of the flowerpot needs to be perforated, so that the drainage will be better, and the leaves will not change color because of stagnant water.

As mentioned above, if the leaves of the banyan are yellow and rusty, rescue measures need to be taken as soon as possible. If they continue to be ignored, it will seriously affect its appearance and may even wither and wither. Although Qin leaf banyan is well maintained, it also needs to be properly maintained.
