The leaves of the bamboo suddenly turned white, and there were white spots, what is the problem?

The leaves of the bamboo suddenly turn white, and the white spots may be due to insect infestation. Here are some possible workarounds:

1.Cut heavily damaged leaves: If the leaves of the bamboo are already severely damaged, they can be cut off to avoid further pest spread.

2.Strengthen maintenance: If the pest infestation is not very serious, you can strengthen maintenance to improve the resistance of bamboo. This includes proper watering, fertilization, and pruning.

3.Use pesticides: If the pest infestation is severe, it can be treated with pesticides. Choose an effective insecticide, use it as directed, and spray it on the leaves and stems of the bamboo.

4.Replace the potting soil: If the infestation is very severe, it may be necessary to replace the potting soil to completely remove the source of the potting. When changing potting soil, pay attention to choosing healthy soil and proper potting.

Please note that when using pesticides, follow the instructions and be safe. If the problem is serious or cannot be solved, it is advisable to consult a professional horticulturist or plant doctor.

First, your plant is not bamboo.

Second, ** is not very clear, but there is a feeling that it is the cause of the spotted loon. Therefore, you can buy a small bag of the potion of spotted loon flies in the market.

Third, it is very likely to be a fungal disease, so it is recommended to buy some fungicides** and choose carbendazim.

or methyl tobuzin, or allicin.

Like being harmed by red spider (leaf mites), you can spray Sendebao, imidacloprid, aphid mite extreme kill, avermectin.

Look at the picture This pot of pocket coconut is a red spider infestation.

The cause of whitishness is long-term exposure to high temperatures, poor ventilation, and little light. As a result, the plant's ability to resist diseases and insects is reduced, and the growth is slow. If you think it's a lack of growth, it's probably a lack of light and put it on the balcony.

Under the conditions of sun exposure, the chlorophyll sucked by the spider mites is vacant, unable to provide water and nutrients, and quickly changes color and withers.

Suggestion; Place the plants in a bright, well-lit location. Go to the flower market to buy anthers and nutrient solution for killing red spiders, mix with water according to the instructions, and even 2 times a day for 7 days. The pot of hydroponic pothos is also low in light and seriously lacking nutrients.

The nutrient solution is mixed with water according to the instructions, and the two pots of flowers are used at the same time, and new leaves can grow soon. Withered leaves are eliminated naturally.

Summary. Hello dear, the white thing on the bamboo leaves is caused by improper maintenance, you can cut off the leaves with spots to avoid affecting the ornamentation, hydroponic rich bamboo has not replaced the water for a long time, the water quality becomes turbid, the plant can not absorb nutrients normally, and the leaves will also appear white spots, so it is necessary to change the water regularly. When the nutrients are insufficient, the leaves will also have white spots, the amount of fertilizer should be controlled when fertilizing, the appropriate top dressing should be applied according to the growth of the plant, nitrogen fertilizer should be applied during the growth period of the soil culture rich bamboo, a small amount of diluted potassium dihydrogen phosphate foliar fertilizer should be sprayed, fertilization should be stopped in winter, and nutrient solution should be added to the water during hydroponics.

Hello, I've seen your question, I'm sorting out the answer, please wait a while Hello, I've seen your question, I'm now hand-hungry for you, but it takes a little time, please wait patiently, thank you

Hello dear, the bamboo leaves with a long white sail are caused by improper maintenance, you can cut off the leaves with spots, to avoid affecting the ornamentation, hydroponic rich bamboo has not replaced the water for a long time, the water quality becomes turbid, the plant can not absorb nutrients normally, and the leaves will also appear white spots, so it is necessary to change the water regularly.

Summary. Hello, the whitish leaves of the bamboo indicate that something is wrong. The first thing to consider is nutrition, and it is necessary to replenish it with a nutrient solution. Another is light, although bamboo is shade-tolerant, but the lack of light is not bad for its growth.

Hello, the leaves of the bamboo are whitish, which means that there is a problem. First of all, we must consider the problem of nutrition, and supplement it with Li Yinwu nutrient solution. Another is light, although the bamboo is shade-tolerant, but the lack of light is not bad for its growth.

Another is to ventilate more, collect more light in a bright environment, and photosynthesize more, so as to avoid the appearance of white leaves.

Common pests and diseases of bamboos and control methods:

1. Bamboo bush branch disease

Symptoms:Bamboo bush branch disease is a common disease of bamboo, which will seriously endanger the survival of bamboo, a handful of disease on bamboo branches, will produce white rice-like bacteria in the bamboo branch sheath, and then will be infected to other bamboo branches, and even infect other bamboo branches, and eventually cause the decay of the entire bamboo forest.

Prevention and control:If bamboo bush branch disease occurs in the bamboo, there is no particularly good agent to kill, so when maintaining the bamboo, try to observe as much as possible, once the bamboo bush branch disease is found. Sick and sick bamboos should be cut down as soon as possible, and then disinfected to prevent bamboo bush disease from infecting other bamboos.

2. Bamboo stalk rust

Symptoms:If there is bamboo stalk rust, yellow-brown and dark brown raised lesions will appear in the middle and lower pictures of the bamboo, and then these lesions will gradually spread and connect around, and it looks like the bamboo pole is rusty from a distance. The eye affects the growth and ornamentality of bamboo.

Prevention and control:When planting and maintaining bamboo, it is necessary to maintain a reasonable density and strengthen drainage management, which can effectively prevent the occurrence of bamboo stalk rust. Of course, you can also use aminobenzene sulfonic acid, 250 500 times of powder, 0 5 Baumé stone sulfur mixture and other agents to spray diseased bamboo.

3. Bamboo borer

Bamboo borer is a common pest of bamboo, it lives on the bamboo leaves of the bamboo, by eating the bamboo leaves of the bamboo, the bamboo leaves will be eaten by it, if the bamboo borer is too much, it is the bamboo leaves of the bamboo to eat up, so that the bamboo looks smooth. At this time, it is enough to spray insecticides such as 90% trichlorfon 400 times liquid, phosphine 400 times solution and other insecticides to kill bamboo borer.

4. Spodoptera exigua

Although Spodoptera exigua is a kind of noctuidae, its larvae can harm the bamboo shoots of the bamboo, and the larvae grow by eating the bamboo shoots of the bamboo, affecting the reproduction of the bamboo. It was found that Spodoptera exigua can dig up the damaged bamboo shoots as early as possible to eliminate pests, or you can choose to spray with 20% pyrethrin EC L000 2000 times to kill them.

5. Bamboo weevils

Bamboo weevils are not small in their ability to eat the bamboo shoots of bamboo, but also to eat the tender bamboo, so that the young bamboo has poor growth. After discovery, it should be decisively sprayed with green Weilei 300 times liquid insecticide.

6. Aphids

Aphids have the characteristics of small size and fast reproduction, they gather on the main page of the bamboo, and then suck the plant sap of the bamboo, affecting the growth of the bamboo, and also spreading plant diseases. If you find it, you should use 1:6-1:

8 The ratio of chili water, 3000 times of cleaning emulsion and other insecticides are used to kill!

In an unventilated place, it is normal for any plant to have yellow leaves and lose leaves. In this case, it is usually necessary to maintain the humidity of the air, and the watering is moist and not dry.
