In Pakistan, potato is among the main cash crops for the farmers. Common scab (Streptomyces scabies) reduced the quality and market value of potato tubers and environmental hazardous chemicals are used for the control of this disease. In this study, three antagonistic fungi were evaluated for their biological management potential of common scab and maximum inhibition was observed by Trichoderma harzianum followed by Penicillium digitatum and Aspergillus flavus. Disease incidence, yield and disease severity was determined and Randomized Complete Block Design was used for the statistical analysis. This applied work will enhance the seedling growth and biological management will reduce the cost of environmental hazardous chemicals.
