Biological activity of some bacterial isolates against soil borne pathogenic fungi
The antagonistic activity of three bacterial isolates namely Microbacterium terregens, Cellulosimicrobium cellulans and Bacillus amylollquefaciens was evaluated through direct confrontation method and filtrates culture against the growth of Fusarium solani, Fusarium oxysporum, Rhizoctonia solani and Phytophthra cactorum. All bacterial isolates showed the inhibition of the mycelia growth of the ...
متن کاملChemical Control of Nematodes and Soil-borne Plant-Pathogenic Fungi on Cabbage Tranplants.
Six general-purpose fumigants and one fungicide were applied by different methods and evaluated for control of nematode-fungus complexes on cabbage grown for transplant production. All chemicals reduced populations of nematodes and soil-borne fungi but varied greatly in effectiveness. Methyl bromide + chloropicrin (98% methyl bromide + 2% chloropicrin) (MBR-CP gas), DD + methyl isothiocyanate (...
متن کاملRhizobia as a biological control agent against soil borne plant pathogenic fungi.
Rhizobia promote the growth of plants either directly through N2 fixation, supply of nutrients, synthesis of phytohormones and solubilization of minerals, or indirectly as a biocontrol agent by inhibiting the growth of pathogens. The biocontrol effect of rhizobia is due to the secretion of secondary metabolites such as antibiotics and HCN. Siderophore production in iron stress conditions provid...
متن کاملAntagonisitic Potential of Soil Bacteria Against Food Borne Fungi
Bacteria are able to synthesis a wide range of metabolites with fungicidal capabilities. The antagonistic potential of soil bacterial strains (E. coli, Baccillus fortis, B. faragiris, Pseudomonas flourescence and P. malophilia) was assessed by the dual culture technique against some food pathogenic fungi, i.e. Aspergillus flavus, A. niger, Penicillium italicum and P. simplicissmum. The result i...
متن کاملEthylene-insensitive tobacco lacks nonhost resistance against soil-borne fungi.
Enhanced ethylene production is an early response of plants to pathogen attack and has been associated with both resistance and susceptibility to disease. Tobacco plants were transformed with the mutant etr1-1 gene from Arabidopsis, conferring dominant ethylene insensitivity. Besides lacking known ethylene responses, these transformants (Tetr) did not slow growth when contacting neighboring pla...
