Abstract | ||||
A talc formulation of an antagonistic strain of Pseudomonas ffuorescens (Pt- 1) isolated from roots of rice plants was tested for its use as a seed dressing agent. Standard blotter test ,germination test ,vigor test and growing in water agar and peat soil were employed to test the effect of the talc formulation on sorghum seed mycollors .germlnatlon.seed Vigor and rate of growth of seedlings.The formulation when applied to seeds inhibited seed-berne pathogenic fungi like Fusarium moniliforme .F.semitectum.CulVUlaris lunata and Phoma spp < /em>. Also ,saprophtic fungi like ASP6rgiDus navus ,Cladosporium c/sdosporoides and curvularia lunata were inhibited on seeds .The treated seeds showed higher germinalion and the seedlings exhibited Increased vigor .The possibirrty of using powdered talc formulation of Pf-t strain of P.fIuorescens in routine seed treatments is recommended. | ||||
