Question

Tomato wilt is a viral disease.Say true or false.

Answer 1

Chlorosis of the leaves and blotches of green tissue are symptoms of tomato spotted wilt on pepper. All peppers can be severely harmed by the disease.Twisted and distorted leaves are possible. Symptom severity and appearance may vary depending on the pepper cultivar, plant age, virus isolate, and environmental factors.

Complete answer:
The "spotted wilt" tomato disease was first described in Australia in 1915, and its viral aetiology was discovered in 1930. Tomato spotted wilt virus (genus Tospovirus; family Bunyaviridae) (TSWV) was thought to be the only member of the tomato spotted wilt virus group until Impatiens necrotic spot virus was identified in 1989.

TSWV is now the type member of the genus Tospovirus, along with more than a dozen other distinct viruses whose identification has been aided by the use of serological and molecular techniques. Tospoviruses are spread by thrips (Thysanoptera: Thripidae) and replicate in both thrips vectors and plant hosts.

Symptoms:
TSWV infects over 1000 plant species and has a significant economic impact on many agronomic and horticultural corporations. In some areas, the virus has been found to be widespread in the environment due to its ability to infect a wide range of weeds, landscape plants, and native plants. Tomato spotted wilt symptoms vary between hosts and can be variable within a single host species.

Stunting is a common symptom of TSWV infection, and it is usually more severe in young plants. Many infected hosts' leaves develop chlorotic or necrotic rings, and some hosts' fruits may also develop chlorotic or necrotic rings. Some hosts' foliage may develop necrosis, making a diagnosis based solely on symptoms difficult.

Although TSWV is not transmitted through seed, it can cause discoloration of seed produced by infected hosts. As a result, tomato spotted wilt may have an impact on both the quantity and quality of plant products. Furthermore, the movement of infected plant material may result in the introduction of TSWV into a new environment.

True,Tomato wilt is a vial disease.

Note: While eliminating TSWV may not be possible, the incidence and severity of the disease can be reduced through cultural practises such as starting with virus-free plant material, removing all infected plants (because there is no cure once a plant has the disease), controlling weeds, and rotating crops.
