The effectiveness of two Streptomyces spp. strains to control pathogenic fungi was studied in stored maize grain. The trataments included seed disinfection and inoculation with Streptomvces spp. strains previously isolated from maize rhizosphere. Actinomycete inocuIum consisted of filtered suspension and total suspension of fermentor-produced Streptomyces spp. strains biomass. Treatments with Streptomyces spp. strains alone effectively suppressed the developmenl of Aspergillus spp.. Curcularia lunata. and Drechslera maydis and significantly (p < _ 0,05) reduced the incidence of Fusarium subglutinans and Cephalosporium acemonium. Among the inoculation treatments. nondisinfested seed inoculated wilh filtered suspension was the only treatment that did not suppress the development of Penicillium spp. Maize seed inoculation with total suspension of strains was the most effective treatment to control the incidence of seed pathogenic fungi. The development of the Diplodia maydis was onIy suppressed by the combinatíon of seed disinfection and inoculation with total suspension of strains. Although the strains DAUFPE 11470 showed the greatest effectiveness for controlling the fungi pathogenic seed. root and shoot development was reduced by treatment with this strains.The results indicate that Streptomyces spp. strains reduce the incidence of seed pathogenic fungi and have potential as a biological control agent for controlling seed pathogenic fungi. However, an efficient method of seed treatment with the biological control agent must be developed before it can become agricultural practice.
