What medicine is used for cabbage soft rot, and what medicine is used to prevent and control cabbage

Chinese cabbage soft rot, commonly known as rotten pimples, rotten gourds, and rot disease, is a disease caused by bacteria and commonly occurs throughout the country.

Symptoms and identification: starting from the cabbage wrapping, water-soaked rot spots appear at the base of the middle rib of the outer leaf, and the lesion gradually spreads to the periphery and infects other leaves and short stems, at this time the outer leaf wilting often occurs, but it can return to normal at night and on cloudy days. When the disease is severe, it causes the rot of the short stem and root pith, causing the whole plant to collapse, and the rotten tissue has a yellow viscous substance and a foul odor.

After the fungus enters the vascular bundle, it can brown the vascular bundle and enter the leaf vein along the vascular bundle, causing the whole plant to rot.

Prevention and control methods: choose disease-resistant varieties. Strengthen field management.

In addition to crop rotation with non-cruciferous vegetable crops, high ridges or high furrows should be used for cultivation as much as possible, and sowing should be done at the appropriate time. Reduces plant damage. During field operations, damage to plants should be avoided as much as possible, so spraying rows should be set up in the field, that is, 1 blank row should be set up every 10 rows or so, which is only used for field operations such as spraying.

Pharmaceutical prevention and control. After the diseased plants are found in the field, in addition to the timely uprooting of the central diseased plants, the plots with concentrated disease can also be sprayed for control. When the disease is more common, it can be sprayed all over the field.

Generally, spraying starts from the early stage of the disease, once every 7 10 days, and sprays 2 or 3 times continuously. Commonly used agents are: chloramphenicol 100 mg kg, neophytomycin 200 mg kg, agricultural streptomycin 200 mg kg; or vegetable Fengning seed dressing, 150 grams per mu; At the seedling stage, 750 grams of medicine per mu were used, 50 kg of water was added, and root irrigation was used for control.

Cabbage soft rot control measures.

1. High furrow cultivation or ridge cultivation should be used, which can facilitate drainage, reduce the humidity between plants, and facilitate wound healing, so that when irrigating (especially furrow irrigation), the soft rot bacteria in the water are not easy to contact the base of cabbage leaves, so as to avoid infection; It also cooperates with the new high-lipid membrane to prevent the invasion of airborne bacteria.

2. Strengthen management, timely drainage after rain, prevention and control of water accumulation in the field, irrigation should be diligent and balanced, moderate top dressing, timely spraying of strong stems in the growth period, and at the same time, it should also be sprayed in the pregnant stage to make the underground fruit nutrient transport duct thicker, improve the enlargement vitality of the fruit, enhance the disease resistance of the plant, and improve the yield of garlic.

3. For the prevention and control of pesticides, if the diseased plants are found, they should be allocated and brought out in a timely manner, and at the same time, they should be sprayed with the targeted agent streptomycin sulfate or agricultural streptomycin according to the requirements of plant protection, and cooperate with the spraying of 800 times the new high-lipid film to enhance the efficacy, improve the utilization rate of the active ingredients of the agent, and consolidate the control effect.

Cabbage soft rot, also known as rot disease, rotten pimple, sauce bucket, deganging, etc., occurs all over the country. The general incidence rate is between 3% and 12%, the rate of diseased plants can reach 30% in severe cases, and the loss can reach more than 50% in the most severe cases.

72% agricultural streptomycin soluble powder 3000-4000 times; 70% dixone wettable powder 800 1000 times liquid irrigation roots; 1500 times of 46% copper hydroxide water-dispersible granules + 750 times of 50% chlorobromoisocyanuric acid wettable powder; 47% Chunlei Wang copper wettable powder 500-700 times liquid. When spraying, we should focus on the petiole and stem base close to the ground, and focus on the plants that have begun to develop the disease and the healthy plants around them. Generally, spray l times every 6 to 7 days, and spray 3 to 4 times in a row. FYI.

Chunlei mildew cracks erectin has a little effect, but it is not formal, Chinese cabbage soft rot, bacterial disease, smelly, serious source argument to remove, can be used streptomycin, leaf huzole, occultamine, mesomycin deficiency, thiamium copper, thiasen copper, quinoline copper, chlorobromoisocyanuric acid, polymyxoid bacillus and other potassium dihydrogen phosphate spray control, interval 5 days in continuous spraying 2 to 3 times.

**The main drugs for cabbage soft rot are: streptomycin sulfate or agricultural streptomycin 150-200ppm; 70% dixone wettable powder 800-1000 times liquid; DT fungicide 700 times; Neophytomycin 200ppm; 60% chlorothalonil wettable powder 500 times; 50% ammonium dyssen wettable powder 600-800 times liquid. It should be sprayed in advance for prevention, and the plots that have been affected should be used 3-4 times in a row, with an interval of about a week.

Cabbage (scientific name: brassica pekinensis rupr.).), Brassica of the cruciferous family, known as the "king of vegetables".

Cabbage is native to northern China, cultivated in the north and south, and was introduced to Japan, Europe and the United States in the 19th century. It has wide green leaves and white cabbage gangs, and multiple leaves are tightly wrapped together to form a cylinder, most of which form a dense head, and the leaves that are wrapped in it are pale yellow due to the lack of sunlight.

**The agents of cabbage soft rot are: sulfate chain town such as mycin, agricultural streptomycin, neophytomycin, etc., timely monitoring of the soil to disinfect, the density of bacteria can also be immediately restored as before. In order to prevent and control the soft rot of Chinese cabbage, you can plant cabbage with cabbage, tomato, potato and other vegetables together to reduce the occurrence of diseases.

**The agents of cabbage soft rot are: streptomycin sulfate, agricultural streptomycin, neophytomycin, etc., timely disinfection of the soil, and the density of pathogens can also be restored immediately.

Causes of soft rot of cabbage.

1. Transportation reasons: in the process of transportation there is damage and cracking, the bacteria invade the inside of the cabbage through the surface damage, when the temperature reaches a high humidity of 20 degrees, the bacteria begin to grow wantonly and cause the cabbage to have lesions, 2. Rainy day reasons: with the help of sand splashing in rainy days, the damage cracks at the bottom leaves or petioles of the cabbage invade the inside, 3. Windy weather reasons:

Fungal dust is blown into the vegetable patch, and after rainfall, it seeps into the inside of the cabbage and causes disease.

Cabbage soft rot control.

1. Cabbage can be planted together with cabbage, tomato, potato and other vegetables to reduce the occurrence of diseases;

2. When carrying out agricultural work, try to avoid damaging the cabbage and ensure the integrity of the cabbage to prevent the invasion of germs;

3. After planting and harvesting, the work of vacating the land, turning the land, and drying the field is carried out to promote the decomposition of pathogens and reduce the occurrence of cabbage lesions.

Cabbage soft rot is controlled with streptomycin sulfate or agricultural streptomycin.

Cabbage soft rot initially occurs on petioles and root tips that touch the ground, and the petioles are water-stained, and the outer leaves lose moisture and wilt, and finally the whole plant dies.

At the onset of the disease in the later stage of growth, small spots like water stains first appear, the leaves are translucent, oil-paper-like, and finally the whole plant softens and decays, emitting a special foul odor. When insect pests such as yellow-striped jumping beetles and sugarcane black crickets are severe, a large number of pathogens invade from the wounds, resulting in aggravation of the disease. Sometimes, softening and decay occur during transport.

The pathogen is a short rod-shaped body of the genus Owen, the size is, negative for Gram stain, solitary, twin or short chain, with multiple periflagella and no spores. Chemo-organic trophic type, facultative anaeronomy, metabolized to respiratory or fermentation type, oxidase negative, catalase positive. Colonies on nutrient agar are round, raised, and grayish-white.

Under 20 and high humidity, pathogenic bacteria mainly form colonies centered on the rhizosphere soil of host plants for long-term survival. When it rains, it is splashed with soil particles, and it invades from wounds on the lower leaves and petioles of cabbage and pest food marks.

In windy weather, fungus-carrying dust can be blown into the vegetable patch, and after the rainfall, the upper part of some plants begins to become sick. Pathogens are usually spread by surface water. Its development temperature is 32 33, in case of parasitic plants, that is, rapid reproduction.

Even if the soil is disinfected, the density of germs can be restored immediately.
