Abstract
TENORIO, Reynaldo et al. CONCENTRADOS DE SAPONINA DE CHENOPODIUM QUINOA Y DE CAIPHORA ANDINA: ALTERNATIVAS COMO BIOCONTROLADORES DE HONGOS FITOPATÓGENOS. Rev. Bol. Quim [online]. 2010, vol.27, n.1, pp.33-40. ISSN 0250-5460.
ABSTRACT The biocontroler activity of the extracts from Caiphora andina (PA) M-17 and a saponin isolated from the skin of Chenopodium quinoa Wild. (M-16) were assessed. The decreasing in the rate of growth of the fungal phytopathogen during 12 days was used as indicator of the biocontroler activity of the plant extract. The biocontroler activity was compared against the synthetic fungicide Sistane used as positive control at 1 mL/L. The M-16 showed an inhibition of 42% of the Aspergillus flavus. When the plant extracts M-16 and M-17 were used against Ulocladium spp an inhibition of 35% and 36% was achieved respectively. Fusarium spp was susceptible in 47%. Aspergillus flavus was inhibited in 42% during 4 days by saponin M-16. Thus, this research shows the potential use of plant extracts including saponins as controler agents of phytopathogenic fungi.
