How to prevent and control chili bacterial wilt is excellent, and what is the best medicine to contr

Chili wilt, also known as wilt, is a soil-borne bacterial disease that is mainly invaded through wounds in crop roots. Mix seeds with dimethazine, and evenly mix seeds with grams of original drug per kilogram of seeds. During land preparation, the applied agricultural fertilizer should be fully fermented and decomposed at high temperature, and potassium fertilizer should be appropriately applied during the growth period, which can effectively inhibit the spread of bacterial wilt bacteria in the host and soil.

The drug is applied at the beginning of the disease. You can choose to irrigate the roots with 72% agricultural streptomycin 4000 times, 77% copper hydroxide wettable powder 500 times, 50% zeb zebsen wettable powder 1000 times, 50% copper succinate wettable powder 500 times, etc., and each plant is filled with liters.

A: At present, there is no effective method for the disease, mainly relying on the usual prevention. The specific measures are:

Regular vaccination, in spring and autumn every year, in addition to the adult pigs generally carried out a swine fever rabbit attenuated vaccine injection, weaned piglets and newly purchased pigs should be timely vaccinated and injected. The rabbitized attenuated swine fever vaccine was diluted with normal saline according to the instructions of the bottle label, and 1 ml of intramuscular injection was injected into both large and small pigs, and immunity could be produced 4 days after injection. In areas where swine fever is common, piglets are injected once at the age of 25 to 30 days after birth, and piglets at the age of 55 to 60 days are injected again after weaning, and the protection rate can reach 100%.

Vaccination of pregnant sows can enhance the ability of mothers and children to resist swine fever virus. Vaccinations are usually given one and a half months before farrowing. Emergency immunization, in the pig herd where the epidemic has occurred, do emergency preventive injection, can play a role in controlling the epidemic and preventing the spread of the epidemic, the injection can start from the pigs in the surrounding disease-free areas and disease-free pig houses, and then inject the same group of pigs, and the sick pigs are generally not injected.

In order to strengthen immunity, the dose can be increased appropriately at the time of injection. Strengthen feeding management, regularly disinfect pigsties, improve the overall disease resistance of the pig herd, and eliminate the purchase of pigs from epidemic areas. Newly purchased pigs should be isolated for 30 days to confirm that they are disease-free, and can only be mixed after being injected with swine fever vaccine.

During the swine fever epidemic, feeding utensils are disinfected every 3 5 days. After the disinfection of sick pigs, completely eliminate manure and dirt, remove topsoil, pad new soil, and pig manure should be accumulated and fermented.

To treat bacteria with bacteria, you can find a compound of microbial series products, or use high-efficiency fungicides, sooner rather than later.

Hello, dear. I'm glad to answer for you, pepper bacterial wilt is generally controlled with azoxystrobin methyl tobuzin. In the early stage of pepper bacterial wilt, 72% agricultural streptomycin 4000 times liquid, 50% zebsen wettable powder 1000 times liquid and other agents can irrigate the roots, each plant is irrigated with 1 time every 10 days, continuous irrigation 3-4 times, and the seeds can also be disinfected before planting to prevent the occurrence of this disease.

You can choose to use 72% agricultural streptomycin 4000 times solution, 77% copper hydroxide wettable powder 500 times solution, 50% zeb zeb wettable powder 1000 times solution, 50% copper glutinate wettable powder 500 times liquid and other agents to irrigate the roots, each plant irrigation solution liters, 1 time every 10 days, irrigation 3 4 times. Hope it helps, dear.

Pepper wilt can be controlled with potassium permanganate. The following measures can be taken to control pepper wilt: agricultural measures.

selection of disease-resistant varieties; Crop rotation with cruciferous or grassy crops for more than 4 years; disinfection of seeds; Remove the diseased plant in time, and sprinkle a little lime on the diseased hole for disinfection and sterilization.

Pharmaceutical prevention and control. The drug should be administered at the beginning of the disease. 72% agricultural streptomycin 4000 times, 77% copper hydroxide wettable powder 500 times, 50% zeb zeb wettable powder 1000 times can be used.

Pepper wilt can be controlled with potassium permanganate. Using 600 times of potassium permanganate, or 300 to 500 times of cupramia, or 800 to 1000 times of 20% quinacethone, the root water is used at the time of planting, and the regular or irregular drenching 2 to 3 times or more after planting to before the occurrence of the disease at the fruit-setting stage can receive a better disease prevention effect than that of drenching after the onset of the disease. On this basis, the above-mentioned drugs are used to continue to pick and block the disease center, and the disease control effect is obvious.

Choose varieties with strong resistance to Fusarium wilt, choose disease-free, coated seeds, and uncoated seeds are disinfected with seed dressing agent or soaking agent.

The summer sun can be used for high-temperature soil disinfection, first ridge, fill with water and then cover with plastic film, close the shed, make the temperature rise, keep the ground temperature below 20 cm above 45, keep it for 20 days, kill soil diseases and pests.

Strengthen land management.

During the growth period of pepper, continuous irrigation and flooding irrigation should be strictly prohibited according to the growth needs of timely topdressing and watering, and the application of enzyme bacterial compost or mature organic fertilizer should be strictly controlled to improve the field humidity.

Agricultural control: 1. Select disease-resistant varieties. Choose well-drained loam or sandy loam plots for cultivation, and do not choose low-lying plots.

Avoid flood irrigation, timely drainage after rain 2, soil treatment, and use solar energy to disinfect high-temperature soil in the summer high temperature season when cultivating in protected areas.

Pesticides. Because my green peppers are sprayed with pesticides every year, I have never had blight, so I should use pesticides to prevent and control them.

Hello, you can use R. solanacearum Rick 90-150 times + garlic oil times for spraying + root irrigation.

Use 2-3 times in a row, with an interval of 2-3 days (spray once a day, spray continuously for three days) Precautions: 1. When mixing R. solanacearum with other agents, it should be diluted as the mother liquor first, and then other products should be added in turn.

2 Garlic oil should be used with caution at the seedling stage.

Prevention and control methods. First, the implementation of crop rotation.

Planned crop rotation can effectively reduce the bacterial content of soil and reduce the occurrence of diseases.

2. Improve the soil.

3. Optimize cultivation methods.

The use of high ridge or semi-high ridge cultivation method, supporting the field furrow system, reducing the field humidity, and increasing the application of sea and Weihai large element water-soluble fertilizer, can promote the growth of crops, improve disease resistance, and reduce the occurrence of bacterial wilt.

Fourth, cultivate strong seedlings.

Nutrient bowls, fertilizer balls, and hotbeds are used to raise seedlings, and dwarf and strong seedlings are cultivated to enhance the disease resistance and disease resistance of crops.

Fifth, the use of grafting cultivation methods.

Once diseased plants are found, they should be removed and burned immediately.

The drug should be administered at the beginning of the disease. You can choose 72% agricultural streptomycin 400 times, 77% copper hydroxide wettable powder 500 times, 77% copper hydroxide wettable powder 1000 times, etc., each plant is filled with liters, once every ten days, 3 to 4 times.

In pepper wilt, cutting the diseased stem close to the ground can reveal a slight browning of the vascular bundles, and a white cloudy sap is secreted from this part. The main symptom is that the plant quickly wilts and dies, and the stems and leaves remain green. The browning part of the diseased stem is squeezed by hand, and the milky white bacterial liquid is discharged.

It is a bacterial disease, and it can be irrigated with streptomycin, pyrazole, octylamide, mesomycin, copper thiazole, copper thiasen, copper quinoline, chlorobromoisocyanuric acid, and Bacillus polymyxoides with rooting agent alternately, with an interval of 5 days in continuous root irrigation 2 to 3 times.

R. solanacearum often invades from the root system, causing the capillary roots to gradually dry up and die at the beginning, and as the disease worsens, the taproot begins to turn brown and is accompanied by rot symptoms. Pull out the diseased plant and cut the stem at the base of the stem, you can see that the internal vascular bundle turns brown, and when you press it lightly by hand, white cloudy juice will appear. Before the pepper is ripe, there is a good pepper tree with the phenomenon of leaf loss and wilting, and it will spread outward with the increase of rain, and the spraying of pesticides seems to be useless, I don't know why, in fact, this phenomenon is the wilt of the pepper.

Chili wilt is a soil-borne bacterial disease, the pathogen is Pseudomonas solanacearum bacteria, which mainly harms crops such as Furu and chili peppers. It is common in various places and the harm is serious, and it spreads quickly under high temperature and high humidity conditions, the damage time is long, and the losses are heavy, which has become the main obstacle in the production of peppers. Most of the diseased plants show symptoms after pepper flowering, only the top leaves wilt and droop at the beginning, the lower leaves appear wilted, and finally the middle leaves also wither.

The pathogen infects through the wound of the root of the crop, enters the vascular bundle after invading the crop, and blocks the conduction system through proliferation.

Generally, when the temperature reaches 20 degrees Celsius, the plant can be infected, so the high temperature is an important reason for the serious occurrence of bacterial wilt, especially in summer, when the temperature rises suddenly, the bacterial wilt is very explosive and difficult to control. However, in the process of growth and development of peppers, they are often infected by pests and diseases, which bring losses to peppers, and bacterial wilt is one of the more common diseases.

The bacterial wilt fungus can enter the soil with the remains of the diseased plant. Long-term survival forms the source of infection. Soil moisture has a significant impact on its survival in the soil.

In alluvial soils with high humidity, it can survive up to 2 to 3 years, while in dry soils, it can survive only a few days. Bacterial wilt is more common in continuous cropping fields and alluvial soil fields with high groundwater level and high humidity. Bed soil should be disinfected and replaced in a timely manner, and crop rotation should be carried out in a planned manner, and at the same time, grafting cultivation methods should be used to prevent it.

Once diseased plants are found, they should be removed and burned immediately.

It should be controlled with pesticides, because bacterial wilt is very hurtful and afraid of pesticides, and spraying pesticides will soon get better.

Sow in advance. Bacterial wilt usually occurs in early to mid-June, so early planting is possible to avoid the peak of the disease and the peak fruiting season. Soil disinfection, heat preservation and moisture preservation.

After the soil is deeply turned, the new high-fat film is sprayed with 800 times of liquid to disinfect the soil, keep warm and moisture, and is conducive to seed germination and growth.

Pesticides. Because my pepper was cured of bacterial wilt after being sprayed with pesticides, it should be treated with pesticides.

First, choose disease-resistant varieties, then rotate with other crops, disinfect the seeds in advance, and add drugs at the beginning of the disease, so that the control can be done.

Disease-resistant varieties can be selected, seeds can be disinfected, and some streptomycin solution can be used for root irrigation in the early stage of the disease.

Be sure to rotate crops and choose some disease-resistant varieties when selecting seeds. Before sowing, the pH of the soil should be adjusted, and the breeding must be carried out in accordance with the scientific method, watering and fertilization should be carried out in accordance with the proportion, and the diseased plants found must be treated in a timely manner, and pesticides need to be sprayed for prevention.

First of all, we should supplement sufficient sunlight and water, and at the same time, we should also have some compound fertilizers, organic fertilizers, nitrogen fertilizers, phosphate fertilizers and urea, so as to be well prevented, and some sterilizing agents should also be used.

It should be controlled with pesticides. Some pesticides can prevent the emergence of bacterial wilt.
