tomato wilt is viral disease explain
Answers
Answer:
The Tomato spotted wilt virus (genus Tospovirus; family Bunyaviridae) (TSWV) was thought to be the sole member of the tomato spotted wilt virus group until 1989 when Impatiens necrotic spot virus was characterized.Tomato Spotted Wilt Virus is a plant virus that was detected in Australia in the early 1900s and rapidly spread to other areas. It is now common in temperate, subtropical, and tropical regions around the world. The disease affects around 800 different plant species, and has become a major issue for tomato growers.Virus spread is rapid in a greenhouse with a western flower thrips population; some plants will develop symptoms within 5 days of feeding by infected thrips.
Explanation:
A tomato is a nutrient-dense superfood that offers benefit to a range of bodily systems. Its nutritional content supports healthful skin, weight loss, and heart health.
Despite the popularity of tomatoes, it was only 200 years ago that they were thought to be poisonous in the United States (U.S.) This is likely to be because the plant belongs to the toxic nightshade family.
Tomatoes are now the fourth most popular fresh-market vegetable behind potatoes, lettuce, and onions. This article will examine their powerful health benefits, nutritional content, ways to include more tomatoes in the diet, and the risks of tomato consumption.
Tomatoes are an intensely nutritious plant food.
The benefits of consuming different types of fruit and vegetable are impressive, and tomatoes are no different. As the proportion of plant foods in the diet increases, the risk of developing heart disease, diabetes, and cancer decreases.
There are different types and sizes of tomato, and they can be prepared in different ways. These include cherry tomatoes, stewed tomatoes, raw tomatoes, soups, juices, and purees.
The health benefits can vary between types. For example, cherry tomatoes have higher beta-carotene content than regular tomatoes.
High fruit and vegetable intake is also linked to healthy skin and hair, increased energy, and lower weight. Increasing the consumption of fruits and vegetables significantly decreases the risk of obesity and overall mortality.
There can be numerous causes of tomato plant wilting, including lack of water, very hot weather, nearby walnut trees, and root-knot nematodes. Gardeners must be careful to distinguish between actual wilting of green leaves and stems and the appearance of dead leaves and stems caused by other diseases and conditions. The major diseases that produce wilting in tomatoes are fusarium wilt, verticillium wilt, and bacterial wilt. Fusarium is, by far, the most common wilt disease in Maryland. Symptoms include yellowing and browning of foliage stunting and wilting with some recovery at night.
fusarium wilt on tomato leavesThe first symptoms appear when fruit begins to mature. Lower leaves turn yellow, sometimes on one side of the plant or one side of a branch. This is followed by leaf and stem wilting. When an infected stem is scraped or split lengthwise you will see browning of the vascular tissue (the tissue closest to the "skin"). The pith (tissue in the middle of the stem) remains healthy. It is the clogging of the vascular tubes (that carry food and water in the plant) that produces the wilting and yellowing. Verticillium proceeds more slowly and the symptoms are more uniform through the plant. Bacterial wilt of tomato is a top-down wilt as opposed to fusarium and verticillium where symptoms begin at the bottom of the plant.
These wilt diseases are all soil borne and can persist for many years in the soil even if no host plants are grown. They can also be brought into a garden on infected transplants or soil. Fusarium wilt does not spread above the ground from plant to plant. Each plant is individually infected when the organism enters the root system.
