Abstract: Tomato (Solanum lycopersicum Mill.) is the most popular vegetable crop grown in the world, crop offers significant nutritional advantages, as it contains significant source of dietary lycopene, β-carotene, vitamin C and antioxidant properties in a low energy dense food. Several human studies indicated a relationship between a high intake of tomato products and a decreased risk of several types of cancer, atherosclerosis and cardiovascular diseases. Crop is severely affecting many of seed-borne fungal infections. These seed-borne diseases cause both quality and quantity of the seed and may lead to seed abortion or elimination of germination capacity. In order to know the effective bio-agents against this pathogen, the experiment were conducted by different powder formulations of antagonistics. The powder formulations of antagonists’ viz., Trichoderma harzianum Rifai, Pseudomonas fluorescens Migula, Bacillus subtilis Cohnand VAM fungi were taken for seed treatment to test their efficacy in providing protection against seed borne infection under in vitro conditions by rolled towel method. Among the four bioagents tested, Pseudomonas fluorescens at concentration of 0.8 per cent showed least seed infection with maximum per cent germination and vigour index compared to Trichoderma harzianum.
