investigation of antagonistic effect of bacillus subtilis on biological control of sugar beet damping - off disease
due to the high antagonistic activity of bacterium, bacillus subtilis (ehrenberg) cohn, three isolates (b.s.ham, 204 and 202) were selected and their efficacy were studied in control of sugar beetdamping–off caused by rhizoctonia solani , in in vitro and in vivo conditions. in dual culture on pda, all isolates of b.subtilis inhibited mycelial growth of r.solani. significantly, volatile metab...
متن کاملbiological control of rhizoctonia solani damping off of sugar beet with native streptomyces isolates under greenhouse and field conditions
biological control of sugar beet damping-off of rhizoctonia solani ag-4 by two native streptomyces isolates (s2 and c) was evaluated in green house and field conditions. in dual culture, two streptomyces isolates inhibited mycelial growth of r. solani ag-4. besides, volatile components of s2 and c inhibited r. solani mycelial growth for 72 and 74 percentages, respectively. soil treatment either...
متن کاملinvestigation on biological control of sugar beet damping-off disease by some isolates of trichoderma harizanum rafai
due to high antagonistic activity of trichoderma harizanum, 5 isolates t.h.k, t.h.bi, t.h.mo, var33 and torbat vi were selected and their efficacy was studied for controlling sugar beet damping-off caused by rhizoctonia solani, under in vitro and in vivo conditions. antagonistic ability of t. harzianum isolates was investigated as dual culture on pda in concomitant and sequential cultures, 48 ...
متن کاملPossible role of xanthobaccins produced by Stenotrophomonas sp. strain SB-K88 in suppression of sugar beet damping-off disease.
Three antifungal compounds, designated xanthobaccins A, B, and C, were isolated from the culture fluid of Stenotrophomonas sp. strain SB-K88, a rhizobacterium of sugar beet that suppresses damping-off disease. Production of xanthobaccin A in culture media was compared with the disease suppression activities of strain SB-K88 and less suppressive strains that were obtained by subculturing. Strain...
متن کاملbiological control of canola rhizoctonia damping off by application of burkholderia cepacia
biological control of soil borne plant pathogens with antagonistic microorganism has been more attracting interest. especially, burkholderia strains have been intensively investigated as biological agents. the objective of this study was finding an effective biologica control agent against the canola damping off caused by rhizoctonia solani. rhizoctonia damping-off is one of the most important ...
