Title

SURVEY OF BACILLUS SPP. ISOLATES FOR BIOLOGICAL CONTROL OF WHITE ROT OF GARLIC CAUSED BY SCLEROTIUM CEPIVORUM UNDER IN VITRO AND GREENHOUSE CONDITIONS

Pages

  253-262

Abstract

 Sclerotium cepivorum incited white rot is one of the destructive diseases of garlic in Hamedan Province. A total number of 175 BACILLUS strains were isolated from soil and from garlic rhizospheres. The antagonism of the bacterial isolates against Sclerotium cepivorum was evaluated using dual culture method. Ten high level activity isolates which produced inhibition zones were selected for further study. Physiological, biochemical, and morphological characteristics of the isolates revealed that they belonged to the species of BACILLUS. Antifungal activity of the liquid and volatile metabolites produced by the bacterial isolates on pathogen and as well, their ability to produce the enzyme protease and hydrogen cyanide were studied. All the isolates produced volatile as well as liquid metabolites, reducing disease significance through their different effects. Isolates B9, B21 and B12 produced protease, but none produced hydrogen cyanide. The antagonistic activity of bacterial isolates was evaluated against the pathogen, employing soil and seed treatment methods. Greenhouse trial results indicated that all the isolates were able to control the severity of the disease, but isolates B12, B21, B3, B20, and B9 showed their effects in either one of the experimental methods more than 73% Isolates B3 and B21 showed the most effects on reduction of the disease (73-83.3%). All the isolates significantly (P£0.01) promoted growth factors in garlic plant.
