Potato (Solanum tuberosum L.) is one of the most nutritious sources of food in the world. It has been recognized as a wholesome food and the richest source of energy in most of the countries of the world where, it forms an important part of the human diet. Among the various disease of potato, soft rot caused by Erwinia carotovora subsp. carotovora is the major potato tuber rot disease. Results revealed against Erwinia
carotovora, that the maximum growth inhibition (49.61%) was found in Pseudomonas fluorescens after five days of incubation and was statistically superior over rest of the antagonists tested. Other antagonists viz., Trichoderma viride (4.46%) did not effectively inhibit the growth of E. carotovora.
Keywords: Solanum tuberosum L., Erwinia carotovora, Trichoderma viride.
