What disease is Phalaenopsis most likely to get? How to deal with Phalaenopsis easily getting sick?

What are the common diseases of phalaenopsis? 1. Anthranose: Phalaenopsis is mostly infected with anthrax because the environment provided is too humid and the ventilation environment is too poor.

Once infected, there will be small spots on the leaves, which will gradually expand into black-brown or yellow-brown lesions. After discovery, it is necessary to treat it in time, ventilate more, strengthen fertilizer and water management, improve the growth environment, and improve disease resistance. In addition, it is necessary to spray the drug, the drug is mancozeb, once a week, spraying two or three times can be effective.

2. Botrytis cinerea: During the management period, the environmental temperature of the plant is too low and too humid to be infected with gray mold, and the flowers are vulnerable to damage when the disease occurs. In the early stage, the flowers and sepals are prone to water-stained spots, and in the later stage, the spots will enlarge and appear as round patches, and in severe cases, they will fall flowers.

After discovering it, ventilate it more and let it bask in the sun more. Also cut off diseased flowers to avoid infection. In the later stage, Sukrin should be sprayed, once every ten days, and two or three times will be effective.

3. Soft rot: This disease mostly occurs in high temperature and humid environment, harming the leaves of plants. There will be transparent spots on the leaves, and the leaves will rot in the later stage, which is harmful and spreads quickly, so it is necessary to treat them as soon as possible.

The moisture should be controlled, and the spray should be sprayed. The drug can be treated with antibacterial or polyantimycin, sprayed once every ten days, and can be controlled by two or three times. 4. Brown spot disease:

Brown spot disease also occurs in the season of high temperature and high humidity, and there will be brown irregular lesions on the leaves at the onset of the disease, which will cause great damage to the seedlings, and the leaves of the old plants will also yellowish and dry up when they are serious. Polyantimycin should also be sprayed at the time of treatment, once every ten days, and sprayed two or three times to control it. I see that your Phalaenopsis situation is like having anthrax, and you can treat it in time according to the above ** method.

One isBacterial diseases. Common symptoms include sap secretion and decay, which are usually caused by overwatering or through contact with insects or plants. Special attention should be paid to the ventilation of the greenhouse, and the temperature should be adjusted appropriately.

The second isBrown rot. At first, it produces light spots on the body or leaves, and then gradually turns dark brown and wrinkles. Brown rot is easy to occur in the environment of high air humidity, if there is an orchid plant found to be diseased, it is necessary to stop watering, and cut off the diseased part, and apply fungicidal drugs, if the disease is serious or there is a doubt about the expansion of the disease, the disease can be removed or isolated.

Excision, ventilation, keep dry and prevent spread.

Don't think that phalaenopsis will bloom normally after it grows buds. In fact, if the two steps are not done well, Phalaenopsis not only cannot bloom, but also is easy to get sick.

Because this flower bud of phalaenopsis has just grown, it is very insect-friendly, because its bud tip is very tender, and small pests like it very much, especially in the summer when the temperature is high, pests are overflowing, so after the flower buds grow, it must be treated with insect control.

The simplest and most effective way to do this is with this dinotefuran. It is very simple and convenient to use. We just need to take out a pill, open it and sprinkle it directly on the surface of this pot. This not only protects against insects, but also prevents the wound from rotting after the insect bite, which can lead to bacterial infection and cause disease.

Therefore, whether you raise phalaenopsis or orchids, when the buds and arrows have grown, they are the most attractive insects. You have to take precautions, and the same goes for other flowers.

Summary. Dear, phalaenopsis leaves have a lot of bumps on the back of their leaves, which may be due to phalaenopsis being infected with a disease called "leaf spot". Leaf spot is a disease caused by bacteria or fungi that can form raised tumours or spots on the back of Phalaenopsis leaves.

May I ask all flower friends, what kind of disease is Phalaenopsis?

How to send **.

I have a lot of tumor-like stuff growing on the back of my Phalaenopsis leaves.

What color. What other symptoms are you talking about?

It's just that a few leaves have these on their backs, and nothing else.

I'll check it out for you. Do you have every piece of it?How long has it been?

I don't know how long it has been, but I suddenly found it, so scary.

I sent it to you.

Dear, Phalaenopsis has a lot of bumps on the back of its leaves, which may be due to a disease called "leaf spot". Leaf spot disease is a bacterial or fungal disease that causes raised tumours or spots to form on the back of Phalaenopsis leaves.

1.Cut off infected leaves or raised bumps to prevent the spread of germs. 2.

Clean up the diseased area, clean the leaves, disinfect the tools and the surrounding environment. 3.Use fungicides to spray the affected area, such as carbendazim, copper sulfate, etc., and those who are missing should be used according to the drug concentration and use method on the instructions.

Never overwater.

Phalaenopsis is susceptible to anthrax, gray mold, scale disease, and whitefly. When the Phalaenopsis plant has pests and diseases, to be in time for it, we need to cut off its diseased leaves, if the situation is serious, spray it with insecticides, and the methods for different diseases are different.

1. Anthrax

Phalaenopsis is prone to anthracnose, in a high temperature, high humidity and unventilated environment it is prone to this disease, when the disease occurs, it will cause its leaves to appear brownish-black round spots, and finally will gradually expand outward, after the appearance of this disease, we need to cut off the diseased leaves, and then spray with special drugs**.

2. Botrytis cinerea

If not properly maintained, phalaenopsis is also prone to gray mold, when the disease occurs, its leaves will appear gray-white mold, which will eventually lead to the rot of its leaves, in a wet and cold environment it is easy to appear this disease, this time it needs to be sprayed with drugs, but also to strengthen management.

3. Scale insects

Phalaenopsis is also prone to produce scale insects, this kind of insects generally parasitize on the leaves and false corms of plants, which will cause the leaves of the plant to yellow, fall, and it is easy to produce this kind of insects in a hot and humid environment, at this time we need to remove the insects, and if the situation is serious, it needs to be sprayed with insecticides.

4. Whiteflies

Phalaenopsis is also prone to whiteflies, the reproduction ability of this insect is very strong, generally mainly harmful to the leaves and false corms of the plant, after the appearance of this pest, it is necessary to use the emulsion of quick-extinguishing pine to spray the plant**, generally every 1 week or so, spray 2-3 times in a row, so as to completely kill the insects.
