Controle alternativo de fungos associados às sementes Crioulas de feijão (phaseolus vulgaris l.)

Abstract

One of the greatest limitations of beans is the infestation of fungi that cause rot and deterioration of the seeds. This study aimed to identify and control fungi present in seeds of creole beans from the municipality of Cocal-PI. Fungi were found: Cladosporium sp., Aspergillus sp., Fusarium sp., Colletotrichum sp., And Alternaria sp. Native plants, quince (Croton blanchetianus) and carnauba (Copernicia prunifera) were used to produce essential oils. The oils were diluted in distilled water in a concentration of 5%, 10%, 15%, 20% and 25%, using 1.0 g of skimmed-milk powder to facilitate solubilization. Five repetitions were performed with both types of control treatments. The data obtained, in the present study with the essential oils from the quince leaf (Croton blanchetianus) (MA) and carnauba root (Copenicia prunifera) (CA), allows us to conclude that the oils were efficient in inhibiting the fungi of the genera: Aspergillus sp., Alternaria sp., Fusarium sp., Cladosporium sp. and Colletotrichum sp. present in the creole bean seeds
