This desktop study evaluates the effect of the genus Bacillus sp biocontrol against plant pathogenic fungi, particularly by inducing antagonistic relations of cell death in terms natural imminently. Fusarium oxysporum is closely related to cases of vascular wilt androot rot in a variety of plants, obstruction of the vessels that circulate plant to cause yellowing of leaves due to the impossibility in the transport of nutrients, major cause of economic losses national agricultural field. Several mechanisms have been established to control this fungus mycelium within which are variable and extensive use of agrochemicals and pesticides, a practice which by its harmful effects to the environmenthas begun to replace the use of Bacillus spp. The action of this bacterial genus biocontrol is mediated by its biochemical profile since they are producing multiple biologically active metabolites in the case of Bacillus subtilis fengycin Iturin A and Bacillus brevis and gramicidin S (1-5) are capable of inhibiting development and normal growth of other microorganisms, suggesting its use for biocontrol of pests in order tostrengthen the existing quality standards in environmental processes.
