Banana planting common disease map banana wilt disease prevention and treatment methods? Banana wilt is a devastating disease, a soil-borne disease caused by the specialization of Fusarium oxysporum in Cuba. It occurs in the banana producing areas of several provinces in southern China, mainly including the No.1 and No.4 races. The No. 1 race is mainly harmed by bananas, and the No. 4 race is harmful to bananas and bananas. Generally, the yield is reduced by more than 20%. The serious fields are even rejected. Let's take a look at the prevention and cure of banana blight.

Causes of banana wilt

Banana wilt is a soil-borne vascular bundle disease, with diseased banana seedlings and diseased soils being the primary source of infection. After the pathogen invades the banana from the root, it spreads to the tuber through the vascular bundle tissue, and the vascular bundle tissue at the infected site is browned, and the pseudo-stem base is inwardly split and the tuber rots. Factors such as high temperature and rain, soil acidity, sandy loam soil, low fertility, soil viscosity, poor drainage, poor permeability of the lower soil and roots of cultivation are conducive to disease occurrence. The susceptible spring planting banana generally begins to develop from June to July, and is aggravated from August to September, and enters the peak of incidence from October to November.

Banana wilt symptoms

1. External symptoms: Adult plants showed a specific yellow color in the lower leaves and outer sheaths, which occurred at the edge of the leaves at the beginning, and then expanded to the middle ribs one by one, which was significantly contrasted with the dark green part of the leaves. There is also a whole leaf yellowing, the susceptible leaves are rapidly wilting, and the yellow leaves become brown and dry, and the last piece of the top leaves are often pulled out late or cannot be withdrawn, and finally the diseased plants die.
2. Internal Symptoms: The cause of banana blight is a vascular bundle disease, and the internal symptoms are obvious. In the middle column and around, there are vascular bundles with yellow-red lesions, which are spotted or line-like. The closer the lesion is to the base of the stem, the darker the root, the wood at the root. The tube turns reddish brown and gradually turns dark brown and dry, the bulb becomes dark brown and gradually rots, with a special odor.

Banana wilt disease prevention and treatment method

1. Strictly restricting banana seedlings and Manila seedlings and the soil attached to them are imported from the ward.
2. In order to ensure that there is no blight in the banana plantation, the disease-free banana seedlings should be planted. The basic method is to introduce from the area where there is no banana wilt. In addition, try to use varieties that are resistant to blight.
3. If a sporadic disease plant is found in the banana garden, it should be immediately uprooted and the diseased plant broken up, put into a plastic bag, add lime and seal the bag mouth, remove it and keep it away from the banana plant to make it rot.
4. In order to eliminate the source of infection and eliminate the opportunity for transmission, disease treatment is an important measure.
5. Increase the application of fertilizer, ditch drainage, enhance the disease resistance of plants, flat land seriously diseased banana gardens can be flooded for half a year or with rice rotation.
6. For the light disease plants, a broad-spectrum fungicide is used to water the roots and stems with water for 30 kg, and the roots and stems are irrigated for 2 to 3 times at intervals of 3 to 5 days to promote root growth, strengthen the plants, and provide disease resistance.
7. In the middle and late stages of the disease, sprayed 41% of polypyridinium-pyrimidinamine 800 times, once every 3 to 7 days, or sprayed with 38% of carbaryl ester 600 times to the base leaf back.

The pathogen of banana wilt can remain in the soil for more than 30 years. There is no pesticide to remove it. Therefore, although there are some simple rice rotations or some organic matter and soil improvement methods, they are all local. Sexual, comprehensive prevention or treatment is still necessary to use disease-resistant or disease-resistant varieties.

Types Of Beans

Beans are mainly soybeans, broad beans, red beans, mung beans, soybeans, black beans, cowpeas, peas, sword beans, lentils, kidney beans, chickpeas, dal and so on.
The main nutrients in beans include carbohydrates, protein and fat. Protein in beans is an important component of beans.
â‘  Protein: Soy protein in eight kinds of essential amino acids the human body needs with the United Nations food and agriculture organization (FAO) recommended are very reasonable compared to the ideal value of soy protein has good amino acid composition pattern, rich in glutamic acid, alanine and aspartate and contains high lysine, methionine and tryptophan (amino acid) sulfur content is low, However, some grains contain high content of sulfur amino acids and low content of lysine, so some grains can be appropriately combined with legumes, which can play a complementary role in protein, so as to improve the nutritional value of food .
â‘¡ Fat: soybean and black bean have higher fat content, while other beans, such as kidney bean, except soybean and black bean, have lower fat content, but their fatty acid composition pattern is better, mainly polyunsaturated fatty acid, mainly including linoleic acid, linolenic acid, etc.
â‘¢ Vitamins: beans contain vitamin A, vitamin B, vitamin C and vitamin E.
â‘£ Minerals: different beans contain different minerals, such as soybeans are rich in iron, kidney beans contain calcium, iron, potassium, magnesium.
⑤ Dietary fiber: beans contain dietary fiber, which is good for the body.
â‘¥ Pigment: soybean isoflavones are one of the flavonoids, mainly exist in leguminous plants, flavonoids is a kind of plant pigment. Soybean isoflavones are secondary metabolites formed during soybean growth. It can compensate for the lack of estrogen in women after age 30, improve skin moisture and elasticity, relieve menopausal symptoms and improve osteoporosis. The estrogen effect of soybean isoflavones affects hormone secretion, metabolic biological activity, protein synthesis and growth factor activity.
