Fugui bamboo pole has white spots on it, what is it?

Leaf spot disease, in the process of planting, Fugui bamboo is very susceptible to upper leaf spot disease because of its poor stress resistance, which affects its ornamentality. Prevent the plants from being too dense and keep them ventilated and light-transmitting. When the growth is too dense, prune in time, and remove the diseased leaves in time.

The bacterium is mainly transmitted through wounds, and the disease is severe under humid conditions. This is due to the high temperature and humidity of the climate at this time, coupled with the frequent wounds caused by typhoons and showers, which makes the disease very easy to spread. The disease is highly contagious and can rot the leaves and stems of plants.

If you do not change the water for a long time, a large number of bacteria will grow in the water, resulting in poor water quality, so that the bamboo poles of Fugui bamboo will soon be white. Water cultivation Fugui bamboo can be changed once a week. Extended Information Precautions for Fugui Bamboo Planting 1. Fugui Bamboo Water Cultivation is also to fertilize it frequently, and the branches and leaves will turn yellow if they lack nutrients.

At this time, as long as you immediately replace it with clean water and drop a few drops of nutrient solution, it can be relieved. 2. If the rich bamboo is put for a long time.

There are white spots on the Fugui bamboo poles, which may be leaf spot. Because of its poor stress resistance, Fugui bamboo is susceptible to upper leaf spot disease.

Hello, thank you for your patience, if there are white spots, it means that there is a lack of nutrient solution.

At this time, it is necessary to replenish the nutrient solution in time or replace the water in time to be in the water, and I hope that it will help you if there are germs.

It is a manifestation that some are going to rot, and the water can be changed.

Aquatic Fugui bamboo is not like soil-cultivated Fugui bamboo can automatically absorb nutrients in the soil, hydroponic Fugui bamboo needs people to regularly add nutrient solution in the water bottle, if there is no nutrient in the growth water, the leaves of Fugui bamboo will grow some white spots, so the maintenance should be added to the product to add a certain amount of nutrient solution.

Summary. 1. The white spots caused by insect pests should be killed in time.

In the process of maintaining Fugui bamboo, sometimes the leaves will grow insects. Common insect pests are red spiders, aphids, etc. Once an insect infestation occurs, the insect will suck and damage the leaves, resulting in white spots on the leaves.

Solution: Carefully inspect the leaves to determine what kind of pest it is, and then use the corresponding pesticide to eliminate it. If the insect infestation is not serious and the number is relatively small, use a rag to remove all the insects. Pay attention to the condition of the leaves in the follow-up to prevent the resurgence of insect infestation.

Fugui bamboo has white flocculent on it.

1. The white spots caused by insect pests should be insecticidal in time In the process of maintaining Fugui bamboo, sometimes the leaves will grow insects. Common insect pests are red spiders, aphids, etc. Once an insect infestation occurs, the insect will suck and damage the leaves, resulting in white spots on the leaves.

Solution: Carefully inspect the leaves to determine what kind of pest it is, and then use the corresponding pesticide to eliminate it. If the insect infestation is not serious and the number is relatively small, use a rag to clear all the insects.

Pay attention to the condition of the leaf slag stool in the follow-up to prevent the resurgence of insect pests.

2. White spots caused by diseases, increase ventilation and sterilizationWhen leaf spot, stem rot and other diseases occur in Fugui bamboo, brown or white spots will also appear on the leaves. It needs to be treated when the cover is closed, otherwise the disease area will become larger and larger, which will directly affect the healthy growth of the plant. Solve the problem of making stuffy stoves:

Move the Fugui bamboo to a place with better ventilation and strengthen ventilation. When the disease is not serious, cut off the damaged leaves; When the disease is severe, spray pesticides to prevent and control it.

3. The white stuffy ridge spots caused by the lack of fertilizer, if the hydroponic Fugui bamboo is not fertilized for a long time, due to the lack of nutrients, the growth of the plant will be getting worse and worse, the leaves will gradually turn yellow, and there are some spots, which look unsightly. Solution: To fertilize Fugui bamboo regularly, hydroponic Fugui bamboo fertilization is very simple, use nutrient solution, drop three or four drops into the water each time, and fertilize two to three times a month.

In winter, when temperatures are low and growth is slow, fertilization stops.

<>1) Specific causes: The most likely cause is insect pests, such as mites, red spiders, etc. Sometimes, pests multiply quickly, so it's important to take action when you find them.

2) Solution: There are two ways. Observe the number of bugs, if not particularly numerous, use a damp cloth to wipe the infested area (including the front and back of the leaves).

Then, rinse the area with plenty of water to flush away as many bugs as possible. It's easy and harmless. However, if there are too many of them, then they can only be eliminated with the help of some pesticides, such as defenfen, avermectin, and so on.

These agents work well and quickly, but they can cause some harm and may also pollute the surrounding environment.

1) Specific cause: If the nutrients are insufficient, white spots may also appear on the leaves. This problem can occur with either soil-grown or water-fed plants.

2) Solution: Appropriate fertilization. Water-fed plants can be treated with some nutrient solution; Soil-raised plants can be moderately supplemented with some organic fertilizer.

1) Specific reasons: This situation is for water-fed plants. If the water is not changed for a long time, the leaves will also have white spots.

1. Pest control.

Specific causes: The most likely cause is the occurrence of insect infestations, such as mites, red spiders, etc. Sometimes pests multiply quickly, and it is important to take measures in time when they are found.

Workaround: There are two ways to do this. Observe the number of insects.

If it's not too much, you can wipe the infected area with a damp cloth. Then, rinse the smeared area with plenty of water to wash away as many bugs as possible. It's easy and doesn't hurt either.

But if there are too many pesticides, you can only use some insecticides to kill them, such as trichlorfon, avermectin, etc. These chemicals are effective and fast, but they may cause some harm and pollute the surrounding environment.

2. Appropriate amount of fertilization.

Specific causes: If nutrients are insufficient, white spots may also appear on the leaves. This problem can occur in plants that grow in soil or water. Solution: Proper fertilization. Aquatic plants can use some nutrient solution; Soil-grown plants can use some organic fertilizer, etc.

3. Change the water regularly.

Specific reason: This situation is aimed at plants raised in water. The leaves will have white spots if they are not changed for a long time. Solution: Change the water regularly. The water should be stored for a few days before changing it. In addition, don't change all the water, leave it to be cautious.

Guangdong called "cane aphid", the mainland is mostly called "white aphid", they often parasitize in the shade of fruit trees and flowers, or parasitize in the leaf axils of grasses, the white cotton wool is the inclusions of insect eggs, the insect body is flat and pink white, crawls slowly and sucks the sap of plants, and the destructive power of crops and fruit trees and flowers and plants is great.

Only a small amount of white aphids in potted plants can be pinched to death by hand in time, if too much, it should be killed with 300-500 times higher concentration of dichlorvos or dimethoate spray (Fugui bamboo needs to break the leaf axils and perfuse poison, they are more resistant than ordinary aphids).

Note: Dichlorvos and dimethoate are relatively low in toxicity, with less residue after application and less harm to people.

The white thing on the rich bamboo is: it should be a white aphid.

Generally parasitic in the shade of flowers, or parasitic in the leaf axils of grasses, the white cotton wool is an inclusion of insect eggs, the body of the insect is flat and pink white, crawling slowly to suck the juice of plants.

Control agent: 50 ml of 25% aphid mite clear emulsifiable concentrate, or 1500 2000 times liquid spray of imidacloprid series products, 60-70 grams of 10% aphid lice; 20% imidacloprid 2500 times; 25% anti-aphid 3000 times liquid spray control.
