Is there a cure for capsicum virus disease?

Pepper virus disease, prevention first, first of all, to prevent aphids, planthoppers, etc., control the source of infection, serious disease strains uprooted. Hydrochloric acid can be used. Morpholinoguanidine, riboside triazole.

Morpholine, bitter. Calcium. Sulfur compound, lentinan polysaccharide, Ningnanmycin, phytoling, etc. plus zinc sulfate plus amino acid foliar fertilizer plus imidacloprid spray.

Apply 2 to 3 sprays in a row 5 days apart.

Paratyphoid fever in piglets is an intestinal infectious disease caused by Salmonella cholera and Salmonella Typhimurium, among others. The disease can occur in pigs of all ages, mostly in piglets aged 1 to 4 months, and is usually transmitted through the digestive tract, but can also be transmitted through contaminated feed and drinking water.

According to the severity of the disease, it can be divided into two types: acute septicaemia, in which some pigs die suddenly before and after weaning. In the course of the disease, symptoms such as abdominal pain and diarrhea may be seen in older patients.

The chronic form is the most common type. Symptoms are subtle at first, and then gradually emaciation, growth arrest, anemia, ocular conjunctivitis, or purulent discharge. Prolonged diarrhea with a watery grayish-white or yellowish-green discharge.

Prevention should be strengthened in the management of feeding, piglet pens to do cold and heat preservation, do a good job of cleaning and hygiene, regular disinfection, scientific feeding and timely weaning, in order to reduce the occurrence of the disease. There are many drugs that have the best effect on this disease, such as antibiotics, furans and sulfonamides. China's existing lyophilized paratyphoid attenuated vaccine can be used according to the label.

The following measures should be taken to prevent and control pepper virus disease: Choose disease-resistant varieties. Seed pesticide treatment.

Soak seeds with 10% trisodium phosphate or potassium permanganate 400 times for 20 30 minutes, wash the liquid medicine on the seeds after removal, and then soak the seeds to promote germination. Timely control of aphids, whiteflies, whiteflies, leaf mites and other poison-transmitting vectors. Seedling drug prophylaxis.

Especially in the summer seedlings, spray the following agents every 10 days or so after emergence: zinc sulfate, or 500 times of mushroom proteoglycans. Field drug prophylaxis.

Spray 1000 times of alkyl alcohol copper sulfate aqueous emulsion, or 100 times of NS-83 anti-antagonist, or 200 300 times of mushroom proteoglycan, spray once every 10 days or so, and continuously control 3 4 times. When the disease occurs in the field, it can be sprayed with Ningnanmycin (fungus and poison) for prevention and control.

Prevention and control methods: disease-resistant varieties are selected in production, such as Zhongjiao No. 4, Zhongjiao No. 5, Su Jiao, Red Luodan, etc. Clean the field, avoid heavy cropping, and rotate crops with onions, garlic, legumes and cruciferous vegetables for 3 to 4 years.

Use silver-gray membrane to avoid aphids and yellow plates to attract aphids. For the prevention and control of pesticides, the agents are: Poison buster, also known as virus A or 20% morpholinoguanidine hydrochloride copper wettable powder, used to prevent and control a variety of viral diseases of tomatoes, peppers and other crops, sprayed once every 7 days with 400 600 times liquid, sprayed 3 4 times in a row; spray with 15% phytopyrethox 60 120 ml with water every 667 m2, spray once every 7 days, a total of 3 4 sprays; 83 inhibitors, before and after pepper planting, spray with 600 1000 ml of 83 inhibitors every 667 m2 with water, spray once every 7 days, a total of 3 4 sprays; When aphids occur in the field, use 40% dimethoate emulsifiable concentrate 1000 times or 50% anti-aphid wettable powder 4000 times for control.

Cultivate strong seedlings, cover with mulch, plant in a timely manner, strengthen water and fertilizer management, and enhance plant disease resistance.

Greenhouse aphid trap yellow plate.

Capsicum virus disease has a variety of symptoms such as fern leaves, mosaic leaves, bright veins, dwarfing, yellowing, necrosis, apical wilt and deformity.

1) Mosaic leaves. The leaves showed irregular dark green and light green spots, and the heart leaves were found in the field, indicating that the plant had been infected with viral diseases. Mosaic leaves are divided into two types: light mosaic leaves and heavy mosaic leaves, light mosaic disease leaves appear slightly green at the beginning of the bright veins, or appear thick and light green mottled, and the mosaic leaves do not shrink.

In addition to showing green and mottled leaves, the leaf surface is uneven, the leaf veins are shrunken and deformed, or the linear leaves are formed, the growth is slow, the fruit becomes smaller, and the dwarf is severe.

2) Fern leaves. The leaves become smaller, shrinking, twisted, and clumped.

3) Dwarfing. The plant becomes shorter, often at the same time as fern leaf clustering.

4) Yellowing. The diseased leaves turned yellow obviously, and the phenomenon of defoliation appeared, and the distribution in the field was uneven.

5) Mingmai. The veins of the leaves become pale and translucent.

6) Necrosis. Some of the tissues of the plant turned brown and died, which was manifested as stripe spots, top wilt, necrotic mottled spots and ring spots.

7) Deformity. The diseased plant is deformed, such as the leaves become linear, i.e., fern leaves, or the plant is dwarf, with many branches, and is clump-like.

Sometimes the above symptoms appear on the same plant, or cause leaf loss, flower loss, and fruit drop, which seriously affects the yield and quality of peppers.

The characteristics of various viral diseases of pepper, almost in the same area, the same variety in the same way appears the same virus, the outbreak starts at about 3% to more than 40% only 2-3 weeks, the whole plant disease from top to bottom, the growth point almost stops growing. The incidence of the disease throughout all provinces, when the incidence rate is less than 5%, each time a bottle of medicine mixed with 15 kilograms of water is sprayed directly, three times all **.

The incidence rate of more than 10% of the first time with the medicine bottle, with 15 kilograms of water and the following dispensing spray, the incidence of more than 40% of the first two times each time with two bottles of medicine and the following formula spray, the incidence of more than 60%, each time with two bottles of medicine with the following formula drug spraying. In addition to the requirements, each time in the future, use a bottle of medicine mixed with 15 kg of water and the following medicine to spray and add.

Capsicum virus disease is also known as chili mosaic disease. Its symptoms are pepper flower leaves, shrunken leaves, dragon heads, falling flowers, falling fruits, etc., which generally cause a reduction of more than 10% to 50% of the yield. The main sources of the disease are cucumber mosaic virus and tobacco mosaic virus, which rely on aphids and other field-borne diseases.

The control measures can be as follows:

1. Plant robust and age-appropriate seedlings, and plant them reasonably densely to prevent high temperatures. It does not overlap with Solanaceae crops and is adjacent to the stubble, creating suitable water and nutritional conditions. Organic fertilizer was mainly used, phosphorus and potassium fertilizer were added, and the amount of nitrogen fertilizer was controlled to promote the early growth and rapid development of seedlings.

2. Prevention and control of viruses: When soaking seeds, treat with 10% trisodium phosphate 400 times for 40 minutes to passivate the virus. **, spray 400 times of potassium dihydrogen phosphate with 500 times of 20% virus A or 1000 times of phytochloride.

To control aphids, it is best to eliminate poisonous plants that have not migrated. The agent can choose 3000 times of abadin; Kung Fu 3000 times liquid.

What kind of medicine is good for <> pepper virus disease? Capsicum virus disease is common in Kaidi and is an important disease in pepper production in protected areas. Let's talk about the prevention and control methods of pepper virus disease for reference.

At present, the drugs on the market for the prevention and treatment of viral diseases include phytoling, 32% nucleoside bromomorpholine guanidine (new formula), anti-disease carb (virus K), virus rick, virus A, virus B, virus killing, etc.

When the condition is severe, a variety of drugs should be mixed: choose 500 times of 20% virus A wettable powder, or 400 times of virus K300, or 1000 times of phytolingl emulsifiable concentrate, or 100 times of NS-83 anti-antagonist, or 400 times of cupramia mixture mixed with Yanda zinc sulfate for prevention and control, spray once every 7 10 days, and spray 2 3 times in a row.

The symptoms of capsicum virus disease are complex and there are many types of manifestations, the most important of which are two types:

Macular mosaic type: dwarf diseased plants, with brown necrotic streaks on stems and branches. The leaves are dark green, light green or yellow-green mosaic mottled flower leaves, sometimes with brown necrotic spots on the veins.

Yellowing and withering type: the diseased plant is dwarfed, the leaves are greenish or yellowish-green, the top leaves of the diseased plants become smaller and narrower, and there are often necrotic plaques (yellowish patches) on the middle and lower leaves, and sometimes the diseased spots are cracked, and the diseased leaves are easy to fall off. In the later stage, the axillary buds were extracted in a state of holding jujube clusters, and the leaves were fern-leafy.

There are many types of viral diseases, and the macula mosaic pathogen is mainly tobacco mosaic virus, and the yellowing blight pathogen is cucumber mosaic virus.

High temperature and drought, heavy stubble, insufficient fertilizer and water, weak plant growth and easy disease. There are many aphids, and if the prevention and control is not timely, the disease is serious, and the light is too strong.

1. Choose disease-resistant and disease-resistant varieties, and it is best to use disease-free (virus-free) seeds. Cultivate age-appropriate and strong seedlings. Avoid heavy cropping and welcome cropping, and rotate crops with non-solanaceae crops for more than 2 years.

2. Strengthen management after planting, promote slow seedlings quickly, early germination, strong plant growth, and improve disease resistance.

Prevention and control methods of pepper virus disease:

1. For pesticide prevention and control, you can choose 100 times the solution of NS-83 inhibitor, which needs to be prevented three times, the first time 10-15 days before planting, the second time after planting to slow seedlings, and the third time in the early stage of fruiting. You can also spray zinc sulfate once in each of these three phases, which also has a certain control effect, or 500 times of 20% virus A wettable powder and 1000 times of plant emulsion. At the same time, it is necessary to control aphids in a timely manner.

2. Select disease-resistant varieties, sow seeds at the appropriate time, cultivate strong seedlings, promote early planting and early germination, appropriate density, increase phosphorus and potassium fertilizer, and water with small water to avoid lack of fertilizer and water. Pay attention to the peak period of fruiting and avoid the peak of viral diseases. From May to June, it is necessary to pay attention to dry and hot air, spray potassium dihydrogen phosphate and water to cool down in time.

Capsicum virus disease, also known as mosaic disease, toxin disease, madness, etc., has become increasingly serious in recent years throughout the country. It is one of the most important diseases of pepper, which occurs in spring and autumn, and the most serious disease is in autumn pepper and autumn pepper. Due to the harm of viral diseases, the yield of bell pepper type is generally reduced by 5%-10%, and the yield of long horn pepper type is reduced by about 10%.

Pathogen observation: The pathogens are cucumber mosaic virus, tobacco mosaic virus and potato X virus. The first two are the main ones. In peppers, tobacco mosaic virus and potato X virus cause phylogenetic mosaic symptoms, and different strains of tobacco mosaic virus cause phylogenetic mosaic, systemic ring spots, and stripe symptoms, respectively.

Infection cycle: cucumber mosaic virus has a very wide host range, and the source plants are very common. In the field, it mainly relies on aphids to migrate and spread poison, and the main species are peach aphid, radish aphid and melon aphid. Seeds and soil are not transmitted, and frictional transmission is not important.

The main primary sources of tobacco mosaic virus are diseased residues in the soil, while poisonous seeds and cigarettes or dry tobacco are not the main primary sources of infection. In the field, it is mainly transmitted through contact through field operations. The main source of the potato X virus is the potato, which is mainly transmitted by friction and cannot be transmitted by aphids, nor can it be transmitted by diseased residues in seeds and soil.

Prevention and control methods: pharmaceutical prevention and control:

1. Prevention: Use - "Olik" (special for pepper virus disease) 40g per bag mixed with 15kg of water, evenly spray the whole plant. The drug should be used once every 7 days, and then 3 times in a row.

2. **: Use - "Olik" (special for pepper virus disease) 40g per bag mixed with 15kg of water, 2 times per course of medication, 24 hours between the two medications, and then the next course of treatment every 5 days**. Once the disease is under control, it will be switched to a preventive programme.

Agricultural control: aChoose disease-resistant varieties.

b.Clean the fields and rotate crops.

c.Reduction of vectors (vegetable aphid control).

d.Cultivate strong seedlings and strengthen management.

In order to prevent it, add zinc sulfate when spraying in the early stage, and use Cuitong or phytoling.

I think the most important thing is to avoid heavy stubble.

I use it on cucumbers, and the spray of Tianye is a big exhibition, and they are all vegetables, so they should be able to be used.

Pepper virus disease is generally manifested in mosaic leaves, yellowing, necrosis, etc., and in severe cases, it will cause a large number of leaves, flowers, and fruits, affecting the normal growth of crops.

Demer Tianye - Tianye Exhibition, specially developed for viral diseases, can effectively control tomatoes, peppers, potatoes, cotton and other crops of small leaves, yellow leaves, virus diseases.

Capsicum virus disease is common in all parts of the country, and the harm is extremely serious, with a yield reduction of 20-30% in light cases and a loss of 50-60% in severe cases, which is an important disease in the cultivation of sweet (spicy) peppers.

1. Harmful symptoms: There are three types of common symptoms.

a.Mosaic diseased leaves show obvious yellow-green spots, shrivels, or brown necrotic spots.

b.At the beginning of leaf deformity or cluster clustering, the leaf veins of the heart leaves of the plant fade green, and gradually form uneven mottled spots, leaf surface shrinkage, and later thickening of diseased leaves, resulting in yellow-green mottled or large yellow-brown necrotic spots, and the leaf margins are curled upward. The young leaves are narrow and linear when severe, and the upper internodes of the plants are shortened and clustered in the later stage.

Severely diseased fruits have uneven green spots and wart-like protrusions.

c.The main veins of the striped leaves are brown or black necrosis, which extends to the lateral branches and main stems along the petioles, and systematic necrotic stripes appear, often causing early leaf drop, flower drop, fruit drop, and the whole plant dies in severe cases.

2. Pathogenesis: Sweet (spicy) pepper virus disease is mainly caused by cucumber mosaic virus and tobacco mosaic virus. Cucumber mosaic virus has a wide range of hosts, including many vegetable crops, and is mainly transmitted by aphids (beech red aphid, etc.).

Tobacco mosaic virus can survive for a long time in the stump of dried diseased plants, or it can be transmitted by seed infection through contact with sap. Usually high temperature and drought, aphids are seriously harmed when the cucumber mosaic virus is also serious, many years of continuous cropping, low-lying land, lack of fertilizer or the application of unrotted organic fertilizer, can aggravate the harm of tobacco mosaic virus.

3. Prevention and control methods:

Prevention plan: Plan 1: 40g for pepper virus disease, mixed with 15 kg of water, once every 7 days.

Plan 2: Cuijie 50g, mixed with 15 kg of water, 1 time every 7 days.

**Scheme: Plan 1: 40g for pepper virus disease, mixed with 15 kg of water, for 2 days, 1 course of treatment for 7 days, 2-3 courses of treatment, after the disease is controlled, switch to a prevention program.

Plan 2: 40g + 20g of Cuijie for pepper virus disease, mixed with 15 kg of water, used for 2 days, 1 course of treatment for 7 days, 2-3 courses of treatment, after the disease is controlled, the prevention plan is used instead.

Note: In order to enhance its permeability, an appropriate amount of silicone or pure milk can be added.
