摘要: Summary 1. Bacterial blight of cotton is potentially one the most damaging diseases cotton. 2. Its symptoms and adverse effect on yield are described. 3. Control measures include: (i) cultural techniques crop sanitation, destruction residues, as well close seasons rotation; (ii) chemical seed treatments foliar sprays; (iii) breeding resistant varieties. 4. Techniques described for varieties, sources useful genetic plant resistance identified. 5. The complex nature interactions between host resistance, variation in pathogen environment emphasized. 6. Successful resistance-breeding programmes Africa USA reviewed, attention drawn to pressing need varieties India Pakistan. 7. Continued success control bacterial will require integrated that include methods, use chemicals (particularly treatments) cultivation with durable resistance.
