Field experiments were conducted during rainy (kharij) season of 2004 and 2005 to study the effects of various spray treatments (propiconazole, acetic acid, fluorescent Pseudomonas spp and garlic extract) on seed germination, seedling vigour, viability potential and grain mold severity of susceptible '296B' and tolerant 'CSHI6' and 'SVD960 l' genotypes. Spraying panicles with fluorescent Pseudomonas spp at grain-filling stage significantly increased seed germination, improved seedling vigor index and reduced grain mold severity on tolerant and susceptible genotypes. Fluorescent Pseudomonas spp., garlic extract and propiconazole significantly increased a-amylase activity (range 8.30 to 10.15 mg maltose/g/3 min compared with the 4.68 mg maltose/g/3 min. in control) in seedlings raised from seeds with different treatments. Reduction of grain mold severity resulted in improvement in seed quality parameters.
