Cotton leaf curl disease
-
Cotton leaf curl disease (CLCuD), caused by begomoviruses in association with satellite molecules, is a major threat to cotton production causing enormous losses to cotton crop in most of the cotton growing countries including Indian subcontinent.

Cotton leaf curl disease is the major constraint in cotton production in the Indian subcontinent. A field study (2012-2017) was conducted to assess seed cotton yield on Bt cotton cultivars analogous to the symptom rating scales (DRS) of CLCuD. The DRS is used to derive the percent disease intensity (PDI).

Cotton leaf curl disease (CLCuD) caused by cotton leaf curl virus (CLCuV), a geminivirus is one of the most destructive disease of cotton. The losses due to cotton leaf curl disease vary from 10-90% across the cotton growing areas of Punjab, Haryana and Rajasthan. Cotton leaf curl virus belongs to family Geminiviridae, genus begomovirus and consists of monopartite genome with circular, single stranded DNA.

Major threat to highly productive cotton belt of North India is Cotton Leaf Curl Disease exclusively transmitted by whitefly (Bemisia tabaci). The present investigation was carried out at Research farm of department of Agricultural Meteorology, CCS HAU, Hisar Haryana, to evaluate progression of CLCuD and whitefly (Bemisia tabaci) in relation to weather parameters. Three Bt -cotton hybrids were sown at three different dates. Per cent CLCuD incidence increases continuously from appearance to picking.

This is because the incidence and spread of a single virus disease may be dependent on several vectors which have complicated ecologies themselves (Bos, 1986). Whitefly (Bamasia tabaci) transmitted cotton leaf curl virus disease was the major problem in cotton cultivation (Sharma et al., 2006). However, weather has a very crucial role in CLCuD spread and development and also affects its vector whitefly’s ecology.

Cotton is an important fiber cash crop of India and cotton leaf curl disease is the major biotic constraint that can significantly reduce the production and productivity of the crop. Gossypium hirsutum L. suffered losses in Northern part of India mainly in Haryana due to high incidence of cotton leaf curl disease (CLCuD) and “whitefly” which is the vector of this disease. Development of resistant variety to this disease is most effective, long term and safe method to tackle with this problem.

Mesta (Hibiscus sabdariffa) is an important commercial fibre crop after cotton and jute, which belong to the family Malvaceae. The crop is mainly grown for a green leafy vegetable purpose in North Karnataka, India. Mesta crop is being affected by many diseases of which leaf curl disease caused by Begomovirus is a main constraint in its production. The disease is observed to be transmitted by different means mainly by whitefly (B. tabaci), dodder (Cuscuta sp.), grafting and sap.

Cotton Leaf Curl Disease (CLCuD) is a devastating disease in cotton and cause seed cotton yield loss upto 80% in Northern India. Transmission of CLCuD by Bemisia tabaci, the role of alternative weed hosts, infested cotton plants is well understood. However, the relationship of viruliferous whitefly population and CLCuD incidence is still not clear. We aimed to pursue a detailed study on the effect of general whitefly population and viruliferous whitefly population on CLCuD percent disease index (PDI) and their correlation.

To the extent of our knowledge, applications of DNA markers in marker-assisted breeding of cotton are handicapped due to low genetic diversity in cotton germplasm. Cotton leaf curl disease, a disease of viral origin, has substantially depressed cotton production in Pakistan, and this disease is also an emerging threat to the neighboring cotton-growing countries like China and India.

CLCuV is one of the most serious causes of cotton damage for which no adequate remedy is available. The possible solution to this problem may be the transfer of resistant genes into the background of agronomical CLCuV-tolerant varieties.
