CATDOLL : CATDOLL: What is chicken aspergillosis? What are the characteristics of fruit tree fungal disease?

1. What is chicken aspergillosis?

Chicken aspergillosis is mainly caused by Aspergillus fumigatus, Aspergillus flavus and Aspergillus niger. Under suitable temperature and humidity conditions, the fungus adheres to feed, bedding and feces and reproduces. It mainly harms chicks. Chicks will be infected when they eat feed contaminated with mold spores and live on bedding. It will present an acute outbreak type, and the mortality rate can be as high as about 30%. Adult chickens are less infected. In addition, during the incubation process, Aspergillus can enter the egg through cracked or washed eggshells, causing embryonic death.

Chicks are mostly infected within 5 days of age. Chicks older than 5 days have enhanced resistance to Aspergillus and the infection rate is greatly reduced. The main symptoms of chicks infected with Aspergillus are difficulty breathing, stretching the neck and raising the head, rapid breathing or gasping with the mouth open, and a large amount of mucus secretions in the mouth. The sick chicks have anorexia, lack of energy, lethargy, and like to drink water. In the later stage, diarrhea occurs, and they quickly become emaciated and die of exhaustion.

Autopsy shows that the air sacs and lungs of the sick chicks have gray or yellowish nodules ranging in size from the tip of a needle to a grain of rice, and liver-like changes are found in some parts of the lungs. Adult chickens infected with Aspergillus often have a chronic course, and the symptoms are basically similar to those of chicks. Commonly, sick chickens have pale combs, bloody and thin feces, become emaciated, and have decreased egg production. Arthritis often occurs in later chickens.

2. What are the characteristics of fungal diseases in fruit trees?

①Rot. Due to the decomposition of pectinase secreted by bacteria, the cells of the roots, stems, tubers, rhizomes, fruits, ears and other thick and juicy organs of the affected plants dissociate, and the tissues collapse and rot, such as the soft rot of cabbage.

② Necrosis. It mainly occurs on leaves and stems, with various spots or scorch. The former is like cotton angular leaf spot, and the latter is like rice bacterial leaf blight.

③ Wilting. It is caused by bacteria parasitizing in the vascular bundle and blocking the vessels or by bacterial toxins, such as bacterial wilt.

④Tumor: It is formed due to the proliferation of host cells and expansion of tissues caused by bacterial stimulation, such as cancer.

⑤ Yellowing and dwarfing. Bacteria that parasitize in the wood cause the plant to turn yellow and shrink.

3. Are you specialized in chicken diseases?

I think chicken disease is professional. Because chicken disease is a professional field. So it is professional

4. How to prevent and control rose fungal disease?

First, drug control. Everyone knows that drugs are the best way to treat house diseases, because different diseases can be treated with different drugs, which can treat various diseases more quickly. Gray mold of roses is a fungal infection, so we need to solve the fungal problem to prevent and control gray mold. Therefore, you can choose drugs such as fenpropimorph and fenpropimorph for treatment. It only needs to be sprayed once every half a month to effectively solve gray mold and allow roses to grow and bloom normally.

Second, reduce the amount of watering. As we all know, gray mold is affected by a humid environment, coupled with a relatively low temperature, so you can keep the soil dry by reducing the amount of watering. This can effectively prevent plants from spitting water due to excessive water, and effectively avoid the occurrence of gray mold. Especially in rainy spring weather, you need to reduce the amount of watering and keep the potting soil moist, which is very effective in preventing and controlling gray mold.

Third, timely pruning. Everyone knows that the occurrence of gray mold is not only related to the external environment, but also to the rose itself. Because the growth of the rose is too vigorous, the branches and leaves will be too dense, resulting in the internal branches unable to get the sun, and the ventilation will be much worse, so gray mold will occur. Therefore, everyone needs to prune off the overly dense branches and leaves. Not only can it allow the branches to get the sun and grow more healthily, it can also reduce the plant's nutrient consumption and produce more beautiful roses. Therefore, timely pruning is very important.

5. How to deal with fish fungal disease?

1. Potassium permanganate bath

1. Cause: Goldfish mold may be caused by traumatic infection. This type of mold takes advantage of the goldfish's body surface to enter. The early stage of mold invasion will not be obvious until white hair grows on the wound. However, at this time, the mold has already entered the goldfish's body through the wound. If it is not treated in time, it will ulcerate and wilted.

2. Treatment method: The breeder needs to fish out the sick fish first to prevent them from spreading the fungus to other fish. Then use potassium permanganate solution to give the sick fish a medicinal bath, once a day, for 20 minutes each time. During the treatment period, the breeder needs to change the water once a day, but the amount of water changed each time should not be too large, and it can be controlled at one-fifth of the total water volume.

2. Malachite green medicinal bath

1. Cause: Goldfish mold may also be caused by bacterial infection, mainly because the water quality is too poor or the food fed carries bacteria. When there is mold on the body of the goldfish, the look will become decadent, and in severe cases, it is easy to rot.

2. Treatment method: The breeder can first install an ultraviolet lamp for them, and turn it on for 4-5 hours a day, which can kill the mold in the water. Then install a heating rod to raise the water temperature to about 25℃. High temperature can also inhibit the growth of mold and prevent the condition from worsening. Finally, use malachite green solution to bathe the sick fish once a day. After the hyphae fall off, the goldfish will gradually get better.

6. How to prevent and control tomato mold disease?

1. When removing diseased fruits and leaves, cover them with plastic bags before removing them to avoid improper operation, the spread of germs and diseases.

2. Seed ozone sterilization: Soak the seeds in ozone water for 40-60 minutes before planting.

3. Large-dose ozone sterilization of empty greenhouses: Before transplanting seedlings, close the vents and sterilize the empty greenhouse with a large dose of ozone gas.

Use DuPont Chloride to prevent and control tomato mildew.

This is tomato leaf mold, which can be controlled by spraying pesticides such as Seco, Carinon, Amicid, Wuyimycin, Leaf Mold, and Anti-Mold.

Use metalaxyl mancozeb to control tomato leaf mold.

Chemical control: You can use Guoguang Fucyprodinil, polyoxin, cyprodinil, fenpropimorph and other pesticides to spray the whole plant for control, focusing on spraying the back of the leaves and the middle and lower leaves.

Tomatoes have mildew, spray carbendazim!

Tomato mildew can be controlled with chlorothalonil, metalaxyl mancozeb, and DuPont Chloride.

In the early stage of the disease, fumigate tomatoes in protected areas with 3-3.75 kg/hm3 of chlorothalonil smoke, or spray with leaf mold dust, chlorothalonil dust or dithiocarb dust, once every 8-10 days. Use alternately.

Leaf mold of tomatoes can be controlled with DuPont Klein.

You can use 45% chlorothalonil aerosol 250g/mu. Apply the medicine after closing the greenhouse in the evening, and place the medicine at 5-7 lighting points for fumigation. You can also spray 5% chlorothalonil powder 1kg/mu. Apply the medicine once every 7-10 days depending on the condition.

7. What is pulmonary aspergillosis?

Pulmonary aspergillosis is a rare fungal infection of the lungs. Aspergillus is widely distributed in nature and mainly parasitizes the human upper respiratory tract. Since normal people have immune defense functions, a small amount of Aspergillus usually does not cause disease. When the human immune system decreases or a large number of pathogens invade the human body, it can cause infection and disease.

8. What is feline aspergillosis?

Cat mold infection is caused by a kind of mold. This mold not only infects cats, but also people will be infected once they come into contact with it. Therefore, it is very important to reasonably prevent mold infection. Moreover, not all cats will be infected. Only some cats with low immunity are very susceptible to infection. Owners should usually enhance the resistance of cats to avoid this disease. This disease is caused by infection with a kind of mold. This mold, which is rich in dry pigeon feces, floats in the air. Once it comes into contact with the skin or is inhaled into the human body, it will cause infection. However, healthy cats are almost never infected. If the respiratory organs are infected, runny nose and sneezing will cause pneumonia; skin infection will cause symptoms such as ulcers and tumors; if the eyes are infected, blindness may occur. Cats with normal immunity will not get this disease, so the abnormal immunity must be cured first. Since the symptoms often start with skin diseases, they should be discovered as early as possible.

9. How to treat goldfish fungal disease?

Black dragon eye is a very obvious case of powder disease. There should also be other complications.

Powdery mildew itself is not a serious disease, the cause is water acidification. When the pH value of water is around 6.0, it is very easy to break out. Just raise the pH value to 8.0 and it will heal naturally. However, since acidophilic dinoflagellates invade the surface of fish and cause wounds, it is easy to cause other bacteria and fungal infections, such as water mold, so anti-infection treatment is also required at the same time.

When adjusting the pH value, be sure to use pH test paper. Dissolve the baking soda in water first before adding the fish. Do not add the baking soda directly into the tank. If the fish eats it directly, there is no need to treat it.

The pH value of water should not be adjusted in one step. The daily increase in pH value should not exceed 1.0. In other words, the pH value of the original water in the tank should be measured first. If it is 6.0, you need to slowly increase it to 8.0 in two days. Generally speaking, the pH value of tap water is about 7.0.

During this period, use a light potassium permanganate solution (light red) for a 10 to 20-minute bath every day. It has the effect of sterilizing and astringing the wound. The water should be at the same temperature.

You will see the powder disappear significantly in about two days.

There is a serious problem with your filtration system and the water quality is not good.

For goldfish breeding, it is recommended to keep them in a bare tank. Use a submersible pump for the water pump. The three-in-one water pump must block the flow and oxygen nozzle. The filter box can be ordered online for a three-layer turnover box drip filter. The physical filter box is a magic carpet + four layers of physical filter white cotton. Two biological filter boxes are used to place the bacterial house and coral bones respectively.

In addition, it is highly recommended not to use so-called nitrifying bacteria. In fact, they are not nitrifying bacteria at all. To put it nicely, they are called nitrifying bacteria growth liquid, but in fact, they are smelly sewage. For newly opened aquariums, since the water body lacks ammonia nitrogen sources, adding organic sewage is of course more conducive to the formation of a nitrification system, but its effect is no different from directly peeing in the aquarium.

What's worse is that it takes at least half a month to establish the nitrification system of a new tank. During this period, if there are fish in the tank and you add a large amount of so-called nitrifying bacteria, the fish will definitely be poisoned by ammonia and nitrite.

Therefore, when you are raising water in a tank with fish, do not add this kind of things.
