Přidat tag | Shrnutí: | The present innovation is based on the use of in vitro cultures (vitro plants) in order to promote the phytoremediation of soils contaminated with pesticides, in particular by the sustained use of herbicides, through a system composed of soil-inoculated plants with mycorrhizal MVA symbionts and bacterial surfactants. In the research, the herbicide triazine ametrine of great persistence was applied to the soil and evaluated three species of MVA: Rhizophagus intrarradices; Glomus. Fasciculatumand Fummeliformis moseae inoculated with banana (Musa paradisiaca) tetraploid clone FHIAT commercial 0630 in the adaptation phase, incorporating the bacterium producing surfactant Pseudomonas fluorescens strain PsFS520505. Among the results, the high degree of mycorrhizae reached was higher, with R. intrarradices (77%) followed by G. fasciculatum (67%) and F. mosseae (43%). On the other hand, the phytoremediative capacity of the evaluated system in the enlistment phase, was more effective with G. fasciculatum (60.7%); followed by R. intrarradices (51.2%) and F. mosseae (4.2%). Extension in the field with the best integral variant MVA G. fasciculatum and P. fluorescens was carried out at 30 days the biodegradation of 38.4% of the residual amethrin and 80% of plant survival, conferring transcendental importance, demonstrating an agroecological approach for the integration of chemical and environmental control in the context of the use of herbicides. In the field, the results doubled the phytoremediator effect of the system and biodegraded 90% of the pesticide within 60 days. |
