Plant extract as a strategy for the management of seed pathogens: a critical review

Abstract Seeds associated to fungal pathogens are efficient vehicles for disease dissemination in the field. Such affect seed quality and longevity, causing a decrease or loss of germination, discoloration, necrosis, decay, addition leading production mycotoxins some pathosystems. To control them several synthetic chemicals used. Nevertheless, use poses risk human health environment. Therefore, there is growing demand alternative methods treatment seeds, such as plant extracts. This review evaluated efficacy extracts seeds. Some used treatment, stand out due secondary metabolic their constitution, which inhibit pathogen growth. The literature showed that 100% studies reported were different evaluated, 63% stated an increase 21% no change 5% mentioned negative interference, 11% did not evaluate aqueous extractors 72% studies. Plant promising replace fungicides 33% studies; however, 67% compare use. extraction required, considering low persistence volatilization pathogens.
