Most promising cotton varieties from renowned research institutes of Pakistan (Ayub Agriculture Research Institute Faisalabad, National Institute of Biotechnology and Genetic Engineering, Nuclear Institute of Agriculture and Biology) and private sector (Four Brothers Groups) were evaluated against bacterial blight of cotton Xanthomonas axonopodis pv malvacearum under field condition. During the month of July diseased leaves were collected from different cotton growing areas and ground in distilled water. Suspension was made after pressing it in muslin cloth.
