Abstract
Cotton, “The White Gold” or the “King of Fibres” enjoys a pre-eminent status
among all cash crops in the country and is the principal raw material for the
flourishing textile industry. It provides livelihood to about sixty million people and is
an important agricultural commodity providing remunerative income to millions of
farmers both in developed and developing countries. Among the foliar diseases of Bt
cotton Alternaria leaf spot caused by Alternaria alternata (Fr.) Keissler and bacterial
blight caused by Xanthomonas citri pv. malvacearum (Smith) Dye are widely
distributed and highly destructive. The Alternaria leaf spot and bacterial blight
diseases are now becoming major foliar diseases in Bt cotton-growing regions of
Gujarat and damaging the foliage to a greater extent.
