Summary

Objetivou-se com este trabalho avaliar o efeito dos extratos de alho e agave sobre Fusarium oxysporum, agente causador da murcha-de-fusário no feijão-vagem. Em ensaio conduzido em laboratório, avaliou-se a germinação de conídios e o crescimento micelial em esquema fatorial 2x5 com seis repetições, cujos fatores foram: dois extratos vegetais em cinco concentrações. Em ensaio realizado em casa de vegetação, foi avaliada a incidência de plantas com sintomas de murcha, trinta dias após o plantio. Os tratamentos originaram-se de um fatorial 2x2x3, sendo os fatores: dois tipos de solo, duas épocas de aplicação dos produtos e três produtos em quatro repetições. Os dois extratos impediram a germinação de conídios e o crescimento micelial na concentração de 40 %. A aplicação dos extratos em solo fértil em época pós-plantio reduziu a incidência de plantas afetadas.


Summary translation

The aim of this work was to evaluate the effect of garlic and agave extracts on Fusarium oxysporum S. The first experiment was driven at laboratory, where was evaluated the spores germination and the micelial growth disposed in a factorial scheme 2x5 with six replicates. The factors were: two vegetable extracts with five concentrations; the second experiment was accomplished in greenhouse, where was evaluated the incidence of plants with symptoms of wilt, thirty days after the planting. The treatments originated from a 2x2x3 factorial scheme with four replicates, being the factors: two soil types, two times of application and three products. The two extracts inhibited the germination and the micelial growth on concentration of 40%. The post planting application of extracts on fertile soil reduced the incidence of affected plants.
