The spotted wilt disease of tomato was first described in Australia in 1915 and was determined to be of viral etiology in 1930 (Figs. 1,2). 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 3. Causal organisms This disease is caused by the species of genus Colletotrichum, which belongs to Ascomycetes. Worldwide, different species of Colletotrichum are reported to cause chilli anthracnose disease (Table 1), In India, among different species known to cause this disease, there are primarily three important species Colletotrichum. 1. Fuzzy, grey, mould growths on any part of the chilli plant including stems, leaves, buds, flowers or fruit. This can be in spots or across the whole plant. 2. Look out for tiny black seed-like structures in the infected part of the chilli plant. 3. Chilli pods can go soft and brown instead of ripening. 4 biotic & abiotic constraints severely affect the yield of chilli. Among the biotic constraints the plant diseases play a vital role in the crop loss. Chilli is effected by sev eral diseases, out of which anthracnose of chilli is one of the important disease. It is also termed as dieback or fruit rot. It is caused by Colletotrichum capsici. This.
