How to prevent and control sunburn in peppers What medicine is used to prevent and control sunburn i

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.

Good evening friends.

Know. How to prevent pepper sunburn?

I'll answer. 1 article.

Supersonic speed is greatest

Prevention and control measures: 1North-south cultivation is carried out so that the fruit surface is less exposed to direct sunlight.

2.To irrigate in a timely manner, especially after the fruit should be watered evenly in time to prevent high temperature, watering should be carried out at 9 12 o'clock.

3.Choose anti-scorching varieties.

4.Reasonable dense planting, maintain a certain size of leaf area, so that the leaves shade the fruit, or intercrop with tall crops to avoid exposing the fruit to the sun.

5.Strengthen fertilizer and water management, so that the branches and leaves are luxuriant, strong but not excessive, and grow steadily. Top dressing outside the roots, spraying 600-800 times of blue calcium, once every 5 10 days, spraying 2 3 times in a row, can enhance the ability of the fruit to prevent daily burning.

6.Early removal of diseased fruits to prevent bacterial infection;

7.Strengthen the control of diseases and insects, timely prevention and control of "three falls" disease, prevent early leaf loss of plants, and use leaves to protect fruits to reduce the occurrence of sunburn fruits.

8.Cover with shade netting to avoid direct sunlight on the fruits.

Control methods: Introduce heat-tolerant and drought-tolerant varieties in high-temperature areas according to local conditions. Implement north-south cultivation, reasonable dense planting, and careful pruning, so that the fruit surface is less exposed to direct sunlight. Strengthen the management of fertilizer and water, so that the branches and leaves are luxuriant, strong but not excessive, stable growth, and enhance resilience.

Pepper sunburn is a physiological disease caused by direct sunlight, and the diseased part is often infected by anthrax or other miscellaneous bacteria and grows mold layer, and even rots, which seriously affects the economic benefits of pepper.

The following methods should be adopted to prevent and control pepper burn: Strengthen field management. The combination of fertilizer and water is reasonable, and the reasonable plant row spacing is used to promote the deep roots and lush leaves of pepper.

Reasonable intercropping with tall crops such as corn or cowpea, and use tall crops to shade peppers. Mulching or small arch covers are used to allow the peppers to seal the ridges before the arrival of the hot season. Under the conditions of protected cultivation, shade nets can be used for shading.

If red spiders, anthracnose, viral diseases, bacterial leaf spots, scabs and other pests and diseases that cause leaf fall occur in peppers, they should be controlled as soon as possible.

If there are many rainy days, it can only be prevented, and the possibility of complete cure is not particularly large.

Capsicum disease is a disease caused by fungi, which is mainly manifested by the appearance of dark spots, yellow spots, rot and other symptoms on the leaves, stems and fruits of pepper plants. The following are the prevention and control methods of capsicum disease:1

Prevention should be the priority, field management should be strengthened, and ventilation, light, and soil should be kept moderately moist. 2.Disease-resistant varieties are used, and pepper varieties with strong disease resistance are selected for planting.

3.Soil disinfection is carried out before planting to reduce the infection of pathogens. 4.

Timely remove the diseased residues and diseased fruit side ridges in the field to avoid the breeding and reproduction of pathogens. 5.According to the condition, drugs can be used for drug prevention and treatment, and fungicides such as copper preparations and wild burning thiophanate-methyl can be used for spraying.

6.Pay attention to fertilization, add trace elements to fertilizer, and enhance the immunity of plants. 7.

For plants that have been diseased, take measures such as pruning and burning in time to avoid the spread of diseases. In short, the prevention and control of pepper disease requires comprehensive measures, focusing on prevention, strengthening management measures, strengthening field disease monitoring, and timely harvesting, transportation, and prevention and control measures to ensure the yield and quality of pepper.

What medicine is used for chili rotten.

It seems to be a lack of calcium.

It can be sprayed with 4000 times of 72 agricultural streptomycin or 500 times of 50 dt fungicide, 1 time in 7 days, 2-3 times in a row.

Hello, if you are deficient in calcium, you can supplement a certain amount of calcium fertilizer.

Do you still use other medicines?

Do you still use streptomycin.

Just use streptomycin.

Is it okay to add calcium fertilizer.

Hello, you can add calcium fertilizer.

Is it OK to use it with other fungicides?

Sugar alcohol calcium, boiled calcium, and calcium nitrate can be sprayed together.

It is also sprayed once every 7 days, sprayed 2-3 times.

In the future, it is necessary to pay attention to calcium fertilizer supplementation in advance.

Physiological diseases are caused by external excavation factors, which can be solved by cultivation methods, and pepper sunburn is no exception. The main approach is to increase the density, reduce direct sunlight, increase soil water and fertilizer, and avoid too much nitrogen fertilizer, etc., which can be a good solution to the yield and quality, because most of the planting of Chaotian pepper is planted in the open air, and the flowering and fruiting time is just in time for the "dog days". As a farmer who has been planting Chaotian pepper for many years, I have never known how to prevent and prevent sunburn to the current prevention and control method year after year, which is to plant reasonably densely, to make the leaves shade each other, or to intercrop with tall crops, such as corn, so as to avoid the pepper fruit is exposed to strong light.

<> my family's spicy Xunyan pepper has the situation that the subject said, sunburn. It rained a lot some time ago, and recently there has been a drought, so the pepper leaves have fallen off a lot. There are not many leaves on the pepper stalk, the sun shines directly on the pepper, and the surface of the pepper is heated unevenly, so there will be sunburn, and the high temperature exposure of the sun will occur, resulting in a lack of water for the pepper plant and fruit, especially in the continuous high temperature weather or after a few days of rainy days, the sun suddenly appears, these two conditions are easy to get sunburn.

To put it bluntly, the skin of the pepper is white, slightly wrinkled, and gradually thinned and easy to break, and the burn part is infected by bacteria and moldy in the later stage, and the pepper is rotten and inedible.

In the continuous high temperature and scorching summer weather, people will not adapt, let alone a crop like chili peppers. Therefore, to reduce the direct sunlight, put a translucent plastic sheet or black sunscreen on the top of the area where the peppers are grown, so as not to affect the management of the peppers. If there is a problem with the root system of peppers, or if the soil is dry, it will affect the absorption of water and nutrients.

Transpiration is strong in hot weather, and the lack of moisture will increase the probability of sunburn. Intercropping with tall crops such as corn. Generally, every 2 meters of a row of corn, the plant spacing of half a meter to one meter, to form a field shade.

Do not over-dense planting. Otherwise, it will affect the normal growth of peppers. It can also reduce the occurrence of viral diseases.

We should spray some pesticides, and some pesticides to prevent pests and diseases, and we should do weeding.

When the sun is poisoning, put a black plastic sheet on top of the pepper, so that the plastic sheet can prevent the arrival of this virus.

When the fruit is exposed to strong direct sunlight, the sunny side forms pale yellow sunburn patches, which become hard and thin, and are easy to break, this phenomenon is called sunburn. The spicy (sweet) pepper fruit damaged by the daily burn disease is susceptible to saprophytic bacteria in the later stage, and the lesions are moldy or rotten.

Spicy (sweet) pepper daily burn disease is a physiological disease, the main reason for this disease is that the leaves are less shaded in the high temperature period, the sun shines directly on the fruit, so that the peel cells are burned, and under the conditions of too small planting density, hot and dry weather, and lack of soil water, the spicy (sweet) pepper plants are dwarf, the leaves are sparse, and the ground shading area is small, which is conducive to the occurrence of solar burn.
