II. Disease and pest control of ginseng banyan

1. Scale insects

In the process of culture, ginseng banyan diseases and insect pests are rare, but when the environment is not ventilated and improperly maintained, there are occasional scale insects. The insect sucks the sap from leaves and twigs with stinging mouthparts. If it is not noticed for a long time, it will also cause ginseng banyan leaves to turn yellow, and even more seriously, ginseng banyan leaves will fall off.

Prevention and control methods: when a small amount of shell insects are found, brush them off manually in time and put them in a ventilated place; when there are too many scale insects, they should be sprayed with medicine, which can be used to kill scale 800-1000 times, and the control effect can be achieved at one time.

When it comes to the diseases and insect pests of ginseng banyan, apart from shell insects, the most common disease is brown spot, which mainly harms the leaves of plants and is one of the main causes of blackening of ginseng banyan leaves. Symptoms: at the initial stage, the diseased leaves will appear round or oval spots, showing purplish brown and turn black in the later stage, and even the leaves will wither and yellow and fall off in serious cases.

Prevention and treatment: when the above symptoms are found, remove the diseased leaves in time and burn them centrally to reduce the source of the disease. At the initial stage of the disease, spray 70% manganese zinc wettable powder 400 times, once every 10 days, 3 times 4 times in a row, the prevention and control effect is good.

3. Other diseases

In addition to shell insects and brown spot, ginseng banyan also suffers from other diseases, such as freezing injury when the temperature is low and burns when the light is too strong. The specific symptoms and prevention and treatment methods are as follows:

① freezing injury

Ginseng banyan is not cold-tolerant, and the indoor temperature should be kept above 10 ℃ in winter. Once the temperature is lower than 6 ℃ and the basin soil is moist, it is easy to cause the young leaves of the plant to fall down due to cold, and in serious cases, it will cause tuber rot and it is difficult to restore vitality.

Control methods: in the process of cultivating ginseng banyan, the temperature should be properly adjusted, the temperature should be controlled at 18-33 ℃, the overwintering room temperature should be above 10 ℃, and the basin soil should be slightly dry.

② burns

Ginseng banyan likes the light and avoids strong light. Once it is exposed to the sun for a long time, it is easy to cause leaf burns, causing part of the leaves to lose green and whiten, or the whole leaves to be burned, and the necrotic parts turn brown and black in the later stage.

Prevention and treatment: when the light is too strong, especially in summer, ginseng banyan should be moved to indoor astigmatism for maintenance; in early spring, late autumn and winter, plants can be moved out to bask in the sun from time to time.

Generally speaking, the efficacy of ginseng banyan is good, and it is easy to raise, so it is very suitable for raising indoors. But once it is neglected to manage, it will be targeted by diseases and insects, thus seriously affecting its ornamental. Therefore, for the sake of the health of ginseng banyan, we must raise it carefully.

What should we do if the bachelors grow worms? pest control of bachelors / 1 pest 2 disease spraying

Single tree, also known as green jade tree, it is a beautiful succulent plant, its straight stem, covered with green, raised indoors is very ornamental. In theory, succulent bachelors are not vulnerable to diseases and insect pests, but in improper conservation, it will also be threatened by diseases and insect pests. So what if the bachelors grow bugs? Next, let's go with the editor to take a look at the pest control of bachelors.

As a common succulent, it is not difficult to cultivate bachelors, but because there are many novices, they will inevitably be improperly maintained, resulting in plant worms getting sick. As for what to do when bachelors grow worms, we should first identify the pests, and then solve the problem of spraying. Specifically, they are all in the pest control of bachelors, so let's move on.

II. Pest control of bachelorous trees

(1) insect pests of bachelorous trees

Because of the strong adaptability, the insect pests of single trees are relatively few, and the insects that want to grow are generally shell insects. The eggs of the insect will be hidden in the bark, and when they grow up, they mainly damage the leaves of the plant, making the buds curly and deformed, which can not grow normally, and if serious, it will also lead to the death of single trees.

Prevention and control methods: when a small amount of shell insects are found, they can be brushed off with a brush and then rinsed with water; then 50% omethoate emulsion or 50% monocrotophos are sprayed, and the control effect can be achieved at one time.

(2) Diseases of bachelors, anthracnose and leaf spot

1. Anthrax

Single trees rarely get sick, but they can also suffer from anthrax when the temperature is high and the air humidity is high. The disease is mainly harmful to the leaves of single trees. at the initial stage of the disease, there are round disease spots on the diseased leaves, then from round reddish brown to gray-white, and then to black-brown and black spots arranged in wheels; in severe cases, the leaves wither and die.

Prevention and control methods: once a single tree suffers from anthracnose, we should immediately cut off the infected branches and leaves and destroy them centrally to avoid re-infection; at the same time, we should spray drugs on sick single trees, such as 700-800 times of carbendazim wettable powder or 500 times of 75% chlorothalonil.

2. Leaf spot

In addition to anthracnose, there is another common disease of bachelors, that is, leaf spot, which often occurs in late autumn and early winter. At the initial stage of the disease, the diseased leaves appear purple-brown spots, if not timely prevention and control, will eventually become gray, endangering the life of single trees.

Control methods: after it is found that bachelors suffer from leaf spot disease, the diseased leaves should not be removed completely in winter to reduce the source of infection in the following year; in addition, the control effect of spraying carbendazim 800 times in time during the onset of the disease is excellent.

With regard to the pest control of single trees, this is the end of the editor's introduction. I believe that if you encounter worms or diseases of single trees again, you should know how to do it! Generally speaking, single trees are not difficult to maintain, as long as everyone can maintain them according to the cultivation methods of single trees. After doing so, the bugs will not come to the door. Finally, may everyone's bachelor trees grow beautifully.
