Abstract

ACEBO GUERRERO, Yanelis et al. Prospect of the use of bacteria in the control Pyricularia grisea (Cooke Sacc.) on rice (Oriza sativa L.). Rev. colomb. biotecnol [online]. 2011, vol.13, n.1, pp.16-22. ISSN 0123-3475.

Rice is an important food supply for a large part of the world population and its consumption rates are very high. Microbial diseases are one of the main causes that provoke low yields and low-quality spotted grains. Although fungi, bacteria and viruses are mostly the responsible for these losses, fungal diseases strike more frequently. Among fungi, Pyricularia grisea, the blast fungus is responsible for up to 100% of reduction in yields, being the blast the most important rice disease in Latin America. To control this pathogen, a strategy of sustainable agriculture might be developed, combining accurately chemical and biological products. PGPB based bioproducts have been considered as an eco-friendly alternative, which favours environment preservation. This work was aimed to approach the current status and outlook of the use of rhizobacteria in the biocontrol of Pyricularia grisea on rice. Main diseases attacking rice, most beneficial PGPB and its mechanisms of action will be discussed too in this review.

Keywords : Plant growth promoting bacteria; rice; biological control; blast fungus.
