BERNAL CABRERA, Alexander; FLEITES POCH, Aliesky  y  SOSA MARTINEZ, Rafael. Antifungal activity of Spathodea campanulata Beauv. aqueous extracts on bean rust (Uromyces phaseoli Pers. (Wint) var. typica Arth.). Ctro. Agr. [online]. 2016, vol.43, n.1, pp. 55-61. ISSN 0253-5785.

In order to evaluate the antifungal activity of Spathodea aqueous extracts, as a viable alternative for the control of bean rust, this work was realize in an field independent farmer in Corralillo municipality, Villa Clara province, between January and May 2014. For this, aqueous extracts from leaves and flowers were applied at 5 and 10 % on BAT-304 bean variety. The experiment was made under a design of random blocks with six treatments and three replications. The extract applications began from 30 days of age (flowering) and the last 65 days, with a frequency of five days. It was objetive determining the infection intensity and rust distribution in each one of the treatments as well as their effect on quantitative variables (number of pustules/leaf, pustules diameter and yield. As results was found that the aqueous extracts of leaves and flowers of S. campanulata, showed antifungal activity against Uromyces phaseoli applied at 10 %.
