A Comparative Study on Curling of cotton leaves –A Viral Disease
Cotton is considered the most significant cash crop in Pakistan. This crop have imparted a significant role in developing the economy of the county. As per different studies, cotton contributes almost 60% in the economy of Pakistan and almost 70% oil used for cooking is produced from cotton. In Pakistan, productivity is going on decreasing continuously due to multiple factors. One of the main factors is leaf curling viral disease. This disease may reduce the boll of the plant up to 73.5% for each plant, the weight of bolls may be reduced up to 33.8%and GOT up to 3.93%, the yield from every plant lessen by 64.5% and seed index 17.0%. CLCuD may reduce upto10% of quality of fiber, length of fiber by 3.44% and rate of elongation by 10 percent. However controlling the cotton curl viral disease will help in increasing production of cotton. In this study all possible aspects of this disease and resistant varieties are discussed for enhancing the cotton production in Pakistan.
