What are the common diseases of monk fish**.

It is a perennial vine of Luo Han Guo, also known as Lahan Fruit, False Bitter Gourd, and Jin Huihuan. Its fruit is extremely nutritious, rich in vitamins and a variety of sugars, with the effect of stopping cough and phlegm, clearing heat and moistening the lungs. It has high edible and medicinal value.

China also has a history of cultivation of more than 300 years. In the process of growth, the breeding and spread of some pests and diseases seriously affected the growth of monk fruit, resulting in reduced yield. Let's take a look at the control methods of common pests and diseases of monk fruit.

1. Viral diseases.

Viruses are the main disease of monk fruit, mainly affecting the leaves and fruits of plants. After infection, the leaves show symptoms of yellowing, deformity, atrophy, and sometimes blistering. In the later stage, the leaves are thick and hard, and gradually turn yellow, so that the number of fruits decreases.

Even after hanging the fruit, the fruit can tuck, often growing abnormally, and the weight is much lower than that of normal fruit. The higher the temperature, the greater the harm of the disease.

Control methods: select detoxified seedlings and soil for planting, strengthen fertilizer and water management, increase the application of organic fertilizer and phosphorus and potassium fertilizer, and improve the disease resistance of plants. Aphids can be controlled by spraying insecticides regularly to avoid spreading the disease.

At the onset of the disease, anti-poison No. 1 and anti-poison 83 can be sprayed once a week, 2-3 times in a row.

2. Anthrax.

Anthrax mainly damages leaves, vines and fruits. When infected, lesions appear. Over time, the lesions will grow larger and turn brown.

If left untreated, these plants will die. In a humid environment, diseased areas can rot, especially after harvesting, causing a large amount of fruit to rot and affecting yields.

Control methods: increase the application of phosphorus and potassium fertilizers to improve disease resistance. At the beginning of the disease, spray methyl tobuzin, Luheng No. 2 and other agents every 7-10 days, and spray 2-3 times continuously.

3. Root-knot nematode disease.

Root-knot nematode disease is caused by root nematodes that damage roots and tubers. Named for the appearance of large and small nodes in roots and tubers, it is the main disease affecting the production of monk fruit. Because the onset site is underground, there are no obvious symptoms in the early stage of the disease, and the aboveground part gradually dies due to lack of nutrients and water in the later stage.

Prevention and control methods: When planting, the soil should be disinfected and the nematodes should take root. When planting, pesticides such as Fuduo should be sprinkled in the hole to reduce the occurrence of diseases.

4. Bud blight.

Bud blight, as the name suggests, damages the shoots of plants. After infection, the young leaves of the plant turn yellow, the young shoots turn brown and die, and the plant growth nodes are damaged, and they can not flower and bear fruit normally. In severe cases, it leads to no harvest.

Control methods: According to the actual production, the occurrence of the disease may be caused by soil boron deficiency and soil acidification, so increasing the application of boron fertilizer can prevent the disease. If the soil is acidified, lime powder or plant ash can also be applied to adjust the pH level.

5. Pests. The main pests of monk fruit are yellow gourd, red spider, scale insect, termite, fly, etc., which mainly harm the leaves, tender parts and fruits of the plant, and affect the yield and quality of monk fruit. Insect outbreaks can result in no harvest or plant death.

Control methods: You can regularly spray insecticides to control pests, and you can also use targeted pesticides to control various pests.

Prevention and treatment of common diseases.

1. Hydroenterosis**:

I'm a seller of Arhats, raising Arhats for 2 years, **Over n Duo Arhats, from the perspective of JS.

You can prepare coarse salt and yellow powder at home, and you can save other medicines.

1。Common enteritis ** method.

If the fish droppings are spherical, it's normal, and if it's very long, then observe more.

If the stool is white, then you have intestinal salt, stop feeding, and add coarse salt to the water temperature 32.

After 3 days, feed a small amount of feed, change 1 3 water, replenish salt, and feed normally until a week later.

2。Rotten head disease Head hole disease** method.

If you find that there is a small hole in the head of the fish, you should hurry up and use a high acid nail to clear the tank, change the water, and wash the bottom sand.

Then, in the fish hole, he dripped some salt water (a little thicker) for 2 days in a row, and he slowly recovered, without leaving a scar.

The causes of enteritis are: feeding indigestible food, such as grass carp, or feeding unclean things, such as unwashed bloodworms, and generally the arhats who get enteritis are more than 5 minutes, and few are less than 5 minutes.

Go to the monk fish bar and take a look, it's quite detailed.

1. Add about 3 taels of salt;

2. Add 10 tablets of oxytetracycline, remove the sugar coating, soak in water and twist;

3. Add potassium permanganate;

After changing the water after 1 3, under 5 tablets of oxytetracycline.

After 7-10 days, the monk fish is basically cured, the white hair is gone, and the burn is healed.

**:(a) Injuries to the lips caused by or during the fishing transport.

b) Bacteria are severely re-infected and then inflamed.

c) Water. Answer: Dysentery is attached to parasitism.

Symptoms: Flushing and swelling of the lips followed by cotton wool-like substances.

**:(a) Sick fish must be isolated.

b) If there is redness, swelling and bleeding alone, give antibiotics.

c) Infected by mixed hydrophosis bacteria, due to the combination of methane blue or malachite green**.

There are also egg flower dry lang soup, small fish boiled soup, carp papaya boiled soup, Lashi sea crucian carp shell fish boiled soup, bee chrysalis Lijiang begonia fruit is made into dry products**, there are bulk, bag, Naxi language called "Dolly Jiubu", is to treat nephritis.

As long as you control the water temperature and water quality when raising arhats, you will not get sick if you feed them on time.
