Keeping a pot of green plants indoors is the choice of many people today, and Fulutong is loved by the majority of flower friends because of its large and green leaves. However, when cultivating flutong indoors, many flower lovers will encounter the phenomenon of long worms, so what about the long bugs? The following are several common diseases and insect pests of Fulutong. Follow the editor to learn the prevention and control methods.

First, Fulu tung long insects

As a common foliage plant, the breeding method of Fulutong is not difficult, but it does not mean that it can be raised at will. Once there is negligence in breeding, Fulutong will not only grow insects, but also get sick, thus affecting the health of the plant. It is understood that the diseases and insect pests of Fulutong are: shell insects, red spiders, anthrax, brown spot and so on. Next, let's take a look at how to control the insects.

II. Disease and insect pest control of Fulutong

1. Scale insects

Although Fulutong is generally not easy to infect insects, it is also easy to develop shell bugs in an environment with poor ventilation and poor light. The insect generally floats and attaches to the surface of the plant leaves, and the secretions pollute the leaves, causing wilting of the leaves and inducing coal fouling disease, causing great harm.

Control methods: when there are few shell insects, you can gently brush them off with a brush and spray white vinegar to prevent them; when there are too many shell insects, spray 1000 times of omethoate in time to control them, once a week, for 2 or 3 times in a row. If it is found in time, the plant can be sprayed with 1500 times of 25% chlorpromazine wettable powder or 40% of fast killing 2000 times during the larval hatching period, which can kill the scale insect directly.

2. Red spider

If you want to say that Fulutong is a long worm, you should also consider it to be a red spider, because it is the enemy of foliage plants. It is understood that red spiders mainly use mouthparts to pierce into the leaves of Fulutong to suck juice, so that the chlorophyll of the plant is destroyed, causing the leaves of Fulutong to turn yellow and even detach.

Prevention and control methods: for red spiders, we should always take precautions and check the back of leaves in time. When individual leaves are damaged, insect leaves can be removed; when more leaves are damaged, propargite, dimethoate, Huachongjing and other drugs should be sprayed as soon as possible to control them.

3. Anthrax

In addition to the long worm, Fulutong can also get sick. Due to lack of light, poor ventilation and too much nitrogen fertilizer, Fulutong will also be infected with anthracnose. If the leaf tip turns black and the leaf has macula, it should be suffering from anthracnose.

Prevention and control methods: diseased leaves were removed and destroyed in time in winter and spring, and the soil was disinfected with quicklime. In the early stage of the disease, 80% anthrax Fumi wettable powder or 50% carbendazim wettable powder is sprayed every 10 days, 3-4 times to take effect.

4. Brown spot

Brown spot, the main disease of Fulutong, generally occurs under the conditions of high temperature, high humidity and poor ventilation. When suffering from this disease, Fulutong leaves will appear round or oval spots, showing purple-brown later become black, or even leaves withered and yellow shedding.

Prevention and treatment methods: when the above diseases are found, the diseased leaves should be removed in time and destroyed centrally to reduce the source of the disease; at the initial stage of the disease, 50% carbendazim wettable powder 600 times or 40% chlorothalonil suspension 500 times, spraying leaves every 10 days, continuously 3 times 4 times, the effect is excellent.

5. Other diseases

① freezing injury: Fulutong is not cold-resistant. In winter, once the temperature drops below 10 ℃ and the basin soil is moist, it is easy to cause the young leaves of the plant to fall down by freezing. In serious cases, it will cause the tuber to rot and it is difficult to recover its vitality. Control method: in winter, move Fulutong indoors to ensure that the overwintering room temperature is more than 10 ℃, and keep the basin soil slightly dry.

② burns: Flutong likes light, but it avoids strong direct light. Once it is exposed to direct sunlight for a long time, it is easy to cause leaf burns, causing part of its leaves to lose green and whiten, or the whole leaf to be burned. Prevention and treatment: in summer, Fulutong should be moved to indoor astigmatism for maintenance.

Diseases and insect pests of Fulutong and its control

Anthracnose of Fulutong

The most common disease of Fulutong is anthracnose, which is caused by lack of light, poor ventilation, excessive nitrogen fertilizer and so on.

Symptoms of anthrax: anthracnose will make the leaves appear watery macula, there will be grayish white and moire in the middle of the leaves, and the small black spots will turn into black in the later stage, causing the plant to show symptoms of drying up.

Control of anthracnose in Fulutong

Control methods of anthracnose in Fulutong

In the early stage of the disease, 80% anthrax Fumi wettable powder or 50% carbendazim wettable powder should be sprayed on the leaf, once every 10 days, three or four times in a row.

In normal maintenance, fertilization should pay attention to the balance of nitrogen, phosphorus and potassium, and put it in a place with sufficient light and good ventilation.

The insect pest of Fulutong the shell worm of Fulutong

The cause of shell insect disease is caused by poor ventilation, poor light, high temperature and high humidity. In these cases, the plant is most prone to shell insect disease.

Scale insect disease symptoms: will engulf leaves, so that the plant growth is poor.

Control of scale insects in Fulutong

The control method of shell insect disease of Fulutong: during the larval hatching period, the plant can be sprayed with 1500 times of 25% prolactin wettable powder or 40% of 2000 times of quick killing or 1000 times of omethoate EC to kill the scale insects directly.

Or use manual to catch the insects, and then spray with medicine to get rid of the diseases and insects completely.
