Efecto de tres residuos industriales de quinua sobre alternaria sp. y botrytis fabae en haba (vicia faba).

Abstract

This research proposes: to evaluate the effect of three industrial residues of quinoa on Alternaria sp. and Botrytis fabae in bean (Vicia faba), carried out in the laboratory of the Department of Biological Sciences of the Faculty of Natural Resources of ESPOCH; a complete random design was used, with nine treatments plus two control controls and three replicates; The treatments corresponded to: residue of the washing obtained from the process of scarification (RLPE), residue of the washing obtained from the dust by the process of scarification (RLPPE) and the residue obtained from the process of the seed washing (RPLS), to 25%, 50% and 75%. The percentage of inhibition mycelial growt rate in syntheticculture médium and percentage ofserverity in plant tissue were evaluated. According to the results obtained RLPE to 75%, produced a inhibition percentage of 27.12% for Alternaria sp, and 4.5 mm/day for Botrytis fabae. For the variable severity of bean leaflets (plant tissue), inoculated with Alternaria sp, RLPE at 75% and RPLS 50%, showed averages of 16.11% and 18% respectively, a superficial to moderate attack was observed and with Botrytis fabae, RLPE at 75% and RPLS 75%, showed averages of 11% and 133% respectively, a superficial attack was observed; achieving in both cases reduce the progression of the disease in plant tissue. From the agronomic point of view it is recommended to use concentrations exceeding 75% of the evaluated solution.
