Green pepper virus disease is extremely harmful, what is the best way to prevent and control green p

This is a physical phenomenon, and it is also a reason why pepper leaves are particularly easy to fall, the soil is dry, there is no water to promote the plant to absorb fertilizer, then the plant will lack water and lack fertilizer, so that the pepper leaves will not have water, after a long period of drought and the sun's radiation balance fertilization. Balance the supply of nutrients, prevent growth and premature aging, and improve plant disease resistance. Balanced fertilization of pepper should be applied with sufficient basal fertilizer, sprayed with strong seedling fertilizer, topdressing with fruit setting fertilizer, and sprayed with puffing fruit fertilizer.

Based on basal fertilizer, it is best to apply "Jizhou" brand pepper disease-resistant and high-yield special patented fertilizer.

When planting peppers, it is necessary to apply fertilizer reasonably, ensure the balance of nutrients in the fertilizer, control the dosage, and prevent excessive nutrients, which will cause premature aging of peppers and lead to leaf loss. Before planting, sufficient basal fertilizer should be applied, and the basal fertilizer is mainly farmhouse fertilizer, and then the nutrient demand of pepper during the flowering period will be greatly increased by insufficient light The density between plants is too large or the growth is too vigorous, the middle and lower leaves overlap each other, and the light is insufficient, and the leaves will yellowing and fall off, which is a physiological phenomenon caused by the respiration consumption of the leaves themselves greater than the accumulation of photosynthesis. According to the test, the light intensity of the compensation point of the pepper is 1500 lux.

Balance the supply of nutrients, prevent growth and premature aging, and improve plant disease resistance. Balanced fertilization of pepper should be applied with sufficient basal fertilizer, sprayed with strong seedling fertilizer, topdressing with fruit setting fertilizer, and sprayed with puffing fruit fertilizer. Based on base fertilizer, it is best to apply the "Ji Zhou" brand pepper disease resistance and high-yield special patented fertilizer, and apply enough high-quality organic fertilizer When planting peppers, it is necessary to fertilize reasonably to ensure the nutritional balance in the fertilizer, control the dosage, prevent excessive nutrition, cause premature aging of peppers, and lead to leaf fall.

Before planting, sufficient basal fertilizer should be applied, and the basal fertilizer is mainly farmhouse fertilizer, and then the nutrient requirements of peppers during the flowering period will be greatly increased.

Combined with the local this there are several situations,1Too much rain, too much moisture in the soil, insufficient oxygen for root growth, and leaf shedding. 2.

High temperature and drought, the water content of leaves decreases, and gradually wilts, disease resistance is weakened, and defoliation problems appear. 3.Leaf spot disease, yellow-green water-invading dots appear on the leaves in the early stage.

It can be sprayed with drugs such as bacterium toxin, morphine and intramuscular water for prevention and control, and continuous intermittent spraying. The formula of the special medicine for pepper blight is 600 times sprayed with garlic oil and wofengsu in R. solanacearum and continuous intermittent spraying. At the same time, viral diseases are mostly spread by aphids and agricultural operations, and can be controlled by trapping aphids.

It is recommended to plant peppers should be sown early at the appropriate time, do not crop continuously, apply more phosphorus and potassium fertilizers, and do not apply nitrogen fertilizers. Clean the field, reduce the source of bacteria, take the previous crops out of the field, concentrate on treatment, dig pits and bury deeply.

Choose seeds with strong disease resistance, disinfect the seeds, sow them at the right time, and fertilize them in time.

Choose disease-resistant varieties, sow seeds in a timely manner, and cultivate strong seedlings. Formula fertilization technology is adopted, organic active fertilizer or decomposed organic fertilizer is applied, watering frequently, and insect nets are used to prevent and control poisonous aphids and reduce the occurrence of viruses.

The methods are as follows: first, choose disease-resistant varieties for planting and disinfect the seeds. Second, reasonable dense planting, choose a suitable sowing date.

Third, strengthen field management, timely control of aphids, and prevent high temperature and drought. Fourth, the implementation of ridge cropping or intercropping with tall crops. Fifth, when carrying out field management such as pruning and pruning, hands and tools should be rinsed with soap and water to avoid plant wound infection.

Sixth, pharmaceutical prevention and control.

Green pepper virus disease is extremely harmful, what is the best way to prevent and control green pepper virus disease?

Hello, choose disease-resistant varieties to plant, generally sharp peppers, conical peppers are more resistant to disease than lantern-shaped bell peppers. Seeds are collected from disease-free plants or seeds are soaked in 10% trisodium phosphate solution for 30 minutes, washed with water and sown. Intercropping or spot planting of maize to reduce the occurrence of diseases.

Plant l rows of corn every 4 ridges, it is advisable to plant east and west, or plant 1 withered corn every 1 meter long, which can play the role of avoiding aphid shading, cooling and moisture preservation, and has a good disease prevention effect. Reasonable dense planting, choose a suitable sowing date. Cultivate disease-free and strong seedlings.

The seedling land should be loose and fertile, early sowing, appropriate sparse planting, reasonable water and fertilizer, the implementation of day and night control of temperature management, and the cultivation of stalks with about 13 leaves is suitable for round and strong seedlings. Thank you for your consultation, I hope it can help you, I wish you a happy life and smooth work!

Severe mosaic virus disease is manifested as leaf greening, leaf and fruit shrunken deformity, uneven leaves, upward curl of leaf edges, linear leaves of young leaves, slow growth, and dwarf of plants. Teratovirosis manifests itself as:

It is also commonly known as fern leaf virus disease, showing different degrees of dwarfing, the top leaf color is generally yellow, and the leaf is cylindrical and curly, uneven. A large amount of falling off with the wind causes the pepper plants to become "light rods" and cannot produce fruits; Necrotic type or deformity is mainly manifested as necrosis or deformity of some tissues of pepper leaves, which seriously affects the growth and development of pepper plants.

To prevent and control whiteflies and aphids in the greenhouse, acetamiprid, pymetrozine, thiamethoxam, spiromel ethyl ester and other agents can be used. 7.If a diseased plant is found, it must be uprooted as soon as possible and taken out of the shed for burial.

If you can't identify the symptoms, you will inevitably fall into hesitation and indecision when it comes to prevention and treatment. Based on this reason, I will help the subject to do some analysis of pepper virus disease from the details, and finally give reasonable medication suggestions.

Poor plant growth is more conducive to the occurrence of diseases, and when the insect infestation is severe, it will also exacerbate the occurrence of this disease. Therefore, I suggest that in order to prevent and treat viral diseases, it is not possible to prevent and treat them from a single drug, but to combine multiple aspects to completely prevent and control the occurrence of this disease. Cultivating disease-free seedlings:

Before sowing peppers, 10% trisodium phosphate can be used for soaking and disinfection for 20-30 minutes. And it is best to choose the seedling plot far away from the vegetable field to avoid the harm of insect pests.

Strengthen cultivation management: firstly, pay attention to water and fertilizer management, keep the soil moist, bring plantar fertilizer and increase phosphorus and potassium fertilizer, and foliar fertilizer can be sprayed during the growth period of pepper, which can effectively improve the ability of pepper to resist viral diseases. At the same time, it is also necessary to uproot the diseased strains and remove the source of poison in time.

Generally, there are a large number of aphids, indicating that aphids are one of the main causes of viral diseases in peppers. And we growers will find that hybrid pepper varieties have a lower incidence, and cone-shaped peppers have a much lower incidence than colored peppers.

Pesticides must be sprayed, and they should be treated accordingly, and pest management should also be done well, and the soil should be loosened in a timely manner.

It can be sprayed with drugs such as pests, mycotoxins, morphine muscle water, etc. For controlled and continuous intermittent spraying. The formula of the pepper blight drug is a 600 times spray made of wiltium, garlic oil, and lyonin, which is sprayed continuously or intermittently.

Prevention and control measures First, choose disease-resistant varieties. The second is to sow seeds in a timely manner and cultivate strong seedlings. The seedlings are required to be short and strong, and they should be planted when the first branch has flower buds.

Third, the seeds are soaked in 10% trisodium phosphate for 20 to 30 minutes, and then washed and germinated, and zinc sulfate is sprayed before seedling, planting, or flowering. Fourth, the use of protected area facilities, 20 25 days before the final frost planting, or the use of plastic film to cover the cultivation, to promote early planting, early fruiting, into the peak stage of the virus disease green pepper has full of flowers and fruits, the root system is developed, the plant is old and healthy, and the disease resistance ability is enhanced.

This viral disease, also known as mosaic disease, is a viral infection that causes slow growth and then flower and fruit drops, which affects the yield of this harvest. If you want to prevent and control it, then you must prevent it according to its disease conditions, viral diseases mainly have viruses left on some branches, this season will not be sick in winter, it will spend the winter on it. After winter, it is spring, and pesticides should be sprayed in spring for prevention and control, spraying pesticides is a good way to kill these viruses in time and avoid damage to crops.

The use of pesticides should be strictly in accordance with this ratio to proportion, and it is best to spray pesticides in the evening to avoid sun exposure affecting the efficacy.

This virus needs to invade when crops have wounds, and it is generally difficult to invade without wounds, which should be noted, so we must avoid insects damaging green peppers when preventing and controlling. Once the crops we grow have wounds, then these diseases and poisons will have an opportunity, so we must avoid those aphids and ants when preventing and controlling, and if so, we must carry out timely extermination and control. <>

In fact, hot and dry weather can also cause the virus。Because of the lack of water, the probability of disease will be very high, so we should water the green pepper in time to avoid too much lack of water, of course, in this case, it is best to strengthen the supply of fertilizer, because in the case of sufficient nutrition, it can effectively strengthen the disease resistance of green coke. <>

However, in the focus of prevention and control, it is still necessary to choose an excellent variety, which can have a good resistance to the virus, and such a variety will be better. There are many varieties on the market that must be disinfected before we plant them, because there are many viruses, which remain in the seeds and come out after winter, so we must use some disinfectant to disinfect them before sowing them.

It is necessary to increase the temperature, add enough fertilizer, and then do a good job of drainage, and use pesticides to prevent this disease.

Our living environment is always in a continuous development process, with the development of science and technology and the progress of science and technology, we will find that many farmers will choose to cultivate chili peppers, chili peppers for our family, especially the man's family is indispensable, he is indispensable for seasoning and the production of a variety of food, the market demand for chili peppers is also very much. As a result, many farmers choose to cultivate chili peppers, but when accompanying chili peppers, we will find many problems, including pests or diseases of chili peppers. <

Pepper virus disease is a disease that is very harmful to the growth and yield of peppers, which can cause very large economic losses, and for crops, the challenge of this disease is also relatively large, so it is important to pay attention to this pepper disease to improve yield and prevent pepper disease. Capsicum virus disease will cause the greatest harm, it is mainly caused by tobacco mosaic virus, cucumber mosaic virus and other viruses, the general source of infection of the virus in the soil or seeds, in the process of transplantation, taking care of peppers, there may be a corresponding infection, then to the corresponding season, the temperature drops, the spread of the virus. When it is suitable for the reproduction of the virus, it will cause the pepper to drop flowers and fruits and leaves, and then cause a corresponding reduction in yield, and the more serious situation may be the failure of the grains.

So for the early detection of this virus is very important for crops, which we can use according to the leaves of peppers. As well as his follow-up changes, to determine whether his empty finger fluid will encounter a viral infection, first we can look at its leaves. If the leaves gradually fade in color, and the surface is uneven, the plant grows slowly, the plant is short, its molecules gradually become more, and the leaves begin to turn yellow, and easy to fall, the plant will appear to be a large area of necrosis, so when this situation occurs, we must be alert to the occurrence of pepper virus disease.

This virus will cause a large area of infection of green peppers, and the defeat and congratulation will also cause some rot inside the inspection surface of the green peppers, resulting in a reduced yield of green peppers or even no harvest.

It will seriously affect the yield, and it will also lead to the death of a large area of the liquid surface, and it will also affect the quality of the product.

Mainly mosaic leaves, yellowing, necrosis and deformity, 4 symptoms, such as the plant becomes very short, the leaf surface is uneven, the fruit becomes small, severe dwarfing, necrosis and so on. If it is serious, it will directly affect the yield of green pepper before closing.

The incidence rate is relatively high, and the speed of transmission is easy to cause serious yield reduction, with yield loss of 20% to 70%.

It is very interesting, that is, the leaves of the plant are normal, the leaves can not see that there is a virus disease, only the black spot on the fruit of the plant like the yellow birch, only on the fruit surface of this situation, but it also affects the sales of the fruit in the later stage, but this is not a virus disease, the virus particle polymer is arranged in a linear shape along the membrane, forming a spherical structure. In the vacuole, the virus polymerizes into an angular lens, and the edge of the vacuole produces a vesicle structure, and the complete virion runs through the plasmodesmata in the cell, and the plasmodesmata part also expands.

Also in the high temperature and humid environment, the growth is very suitable, which brings a lot of losses to us who grow peppers. Sometimes there are many thundershowers in summer, and a short period of heavy rain causes a large amount of water to accumulate on the pepper fields, which will also aggravate the infection of the virus. Viral disease often occurs on the top leaves, the main symptoms are leaf yellowing, mosaic leaves, leaf curling, some leaves and fruits show black-brown streak symptoms, severe defoliation, flower dropping, sometimes individual plants show heart leaves do not stretch, plant growth is slow or the top of the blackening, necrosis.

The control method, first of all, insecticide, can be used imidacloprid, imidacloprid, a net and other agents for foliar spraying. Spraying every 7 to 10 days can effectively prevent the infection of the virus. Spraying antiviral agents can spray yellowing leaf curl virus, which can prevent and reduce the harm of the virus.

The difficulty of the prevention and control of the stripe virus disease is greater than that of the mosaic virus disease, which mainly infects the fruits and stems of the plant, and rarely infects the leaves, and the disease sometimes occurs together with the mosaic virus disease, so we must be careful when judging the symptoms and do not misjudge it as a bacterial disease.

Before raising seedlings, the seeds are treated, which can be pre-soaked in 55 warm water for 30 minutes, and then removed and washed; Then soak the seeds with 10% trisodium phosphate solution for 20 minutes, wash them with water, soak them in clean water for another 6 hours, and finally remove and wash them at a constant temperature of 30 for germination and seedling raising. It is mainly caused by cucumber mosaic virus and tobacco mosaic virus, and is also very closely related to environmental conditions, such as high temperature and drought, aphid poisoning and other factors. The comprehensive prevention and control methods of pepper virus disease include agricultural control methods, environmental protection and non-toxic prevention and control, and pharmaceutical prevention and control.
