Cotton leaf curl disease could be a serious disease of cotton in Asia and Africa that is transmitted using the whitefly Bemisia tabaci. The issue greatly cuts lower round the yield of cotton that is characterised by a few signs and signs and signs and symptoms including leaf curling, stunted growth, and enations round the feet of leaves that often become cup-produced, leaf-like structures. The causative representative is certainly a disease complex comprised of distinct begomoviruses connected obtaining a particular DNA satellite component (DNA ) that’s needed to induce signs and signs and signs and symptoms in cotton. DNA components are a few lately identified, symptom-modulating, single-stranded DNA satellite molecules. In Pakistan and northern India, no under eight types of begomoviruses (either singly or as multiple infections) are connected while using the disease. In northern Africa, just one monopartite begomovirus and satellite are really proven to get connected while using the disease. Another, satellite-like component (referred to as DNA-1) is almost always found in diseased plants, whilst not needed for disease development. Management strategies, like the elimination of cotton within the off-season, removal of potential weed host within the virus complex, and charge of the whitefly vector using insecticides, haven’t impressive. Presently, conventional host plant resistance is considered because the effective control strategy, but you will find number of causes of resistance. The native Asian diploid cotton species (Gossypium arboreum and Gossypium herbaceum ) feel at ease within the condition but aren’t readily became a member of while using the broadly cultivated and-yielding tetraploid Gossypium hirsutum.

Resistant lines produced in Pakistan inside the available G. hirsutum gene pool were selected broadly with the late 1990s but have since fell for any resistance-breaking strain within the disease. Efforts to build up transgenic resistance, using the idea of ‘pathogen-derived resistance’, are really effective but they are not used in the area.
