MATERIALS AND METHODS This experiment was conducted at S.K.N. Chilli mosaic virus (CMV) is common disease of chilli. See the image shown below. Chilli pepper plants can reach heights in the range of 0.5 to 1.5 m (1.6–4.9 ft) tall and although they are perennial species, they are commonly grown as annuals, with fruit being harvested for one growing season. Low pod growth and very poor yields. Based on the symptomatology, it was suspected that these plants were infected by Cucumber mosaic virus (CMV). Here are the ways that this virus can spread. • Insects such as aphids, grasshoppers, beetles, and flies • Mites • Fungus • Nematodes or roundworms • Direct contact from one plant to another • Pollen Symptoms. The most common virus causing the mosaic disease in chilli plants are the Chilli Mosaic virus. https://www.planetnatural.com/pest-problem-solver/plant-disease/mosaic-virus Tomato mosaic virus is one of the oldest described plant viruses. A common vector causes certain strains of Mosaic Virus, while others can be spread through a multitude of hosts. It is extremely easy to spread and can be devastating to crops. Damping off of chilli: This disease prevalently occurs and greatly damages many plants such as chilli, tomato and brinjal belonging to family Solanaceae in India. Click on the following article to learn more about tomato mosaic virus symptoms and tomato mosaic virus treatment. College of Agriculture, Jobner during January 2007 to May 2007. This virus results in leaf curls along with molting. Chilli mosaic CMV- Cucumber mosaic virus 6. If a plant is infected the virus would spread to the whole planting area in a short period of time since the size is very tiny so it can be spread or distributed so easily on the ground even in the air. He called it ‘virus’ (from the Latin virus, meaning poison) to differentiate this form of disease from those caused by bacteria. (ii) Leafhoppers: Examples of viruses transmitted by aphids are: barely yellow dwarf virus, potato virus S, alfalfa mosaic virus, cucumber mosaic virus, potato leaf roll virus, lettuce necrotic yellow virus, and bean mosaic virus, barely mosaic virus, pea mosaic virus, chilli mosaic virus, etc. Among all, the chilli leaf curl virus is the most destructive virus in terms of incidence and yield loss. Symptoms: Symptoms of this disease generally manifest at two stages: Pre-emergence stage and post emergence stage. CMV: Primary: Externally seed borne virus particles to some extent and vector transmitted from other and collateral hosts This virus is spread by aphids and whiteflies and is injected straight into the leaves and stems of chilli plants. Green and yellow patches in a mosaic pattern on leaves. The virus is transmitted by sap and t he important vectors of the virus include Aphis evonymi, A.spiraecola, A.gossypii, Lipaphis erysimi, Rhopalosiphum maidis, and Myzus persicae. In severe cases 100 percent losses of marketable fruit have been reported. Cure. Fruit may be small and distorted, on volunteer Chilli plants and on infected plant debris. Chilli peppers may also be referred to as hot peppers or hot chillis. Survival and spread: TMV: Primary: Externally seed borne virus particles; Secondary: Mechanically transmitted virus particles. In this study, disease symptoms like mosaic and leaf distortion on brinjal, and leaf puckering and malformation on chilli were observed during the field inspection at cherlopalli village, Chittoor district, Andhra Pradesh (AP). Tobacco mosaic virus (TMV) was the first virus discovered. The virus isolates causing mosaic and leaf curl diseases in chilli cultivars were transmitted by aphids and whiteflies, respectively. Curled and Distorted leaves; Slows plant growth. In 1889, Martinus Beijerinck, found that ‘tobacco mosaic disease’ was caused by a pathogen able to reproduce and multiply in the host cells of the plant.
