Abstract

Combination of four different carriers along with Trichoderma harzianum as seed treatement was tested in pot condition against Rhizoctonia solani causing soybean stem rot. Conidial suspension (1 x 108 conidia per ml) of the antagonist was used for seed treatment. Seed germination (%) and yield (g/plant) was found higher in all treatments irrespective of carrier and antagonist used. However, seed germination and yield was found to he on par. The higbest germination (85.33%) and yield (11.78 g/plant) and lowest disease index (1.5) were obtained when seeds were treated with T. harzianum + methylcellulose. Seed treatment with sub-lethal doses of thiram (0.05 and 0.01 %) and T. harzianum showed lower disease index, higher germination and yield than the lethal dose (0.3 %) alone.
