SANCHEZ PEREZ, Yaíma; ROJAS, Miriam M.; AREVALO ORTEGA, Jersys  e  PINO PEREZ, Oriela. In vitro effect of components of essential oils against Pochonia chlamydosporia var. catenulata (Goddard) Zare & Gams and Lecanicillium lecanii (Zim.) Zare & Gams. Rev. Protección Veg. [online]. 2016, vol.31, n.2, pp. 144-147. ISSN 2224-4697.

The aim of this study was to determine the in vitro effect of components of essential oils such as camphor, camphene, piperitone and safrole against the fungal biological control agents Pochonia chlamydosporia var. catenulata (Goddard) Zare & Gams and Lecanicillium lecanii (Zim.) Zare & Gams. The study was carried out using the method of serial dilutions in liquid medium, and concentrations of 1.25, 2.5 and 5 mg.ml^-1 of the chemicals were used. Camphor and camphene were not toxic to fungi in the evaluated range of concentrations. Piperitone and safrole can be used at concentrations lower than 2.5 mg.ml^-1 for L. lecanii and lower than or at 5 mg.ml^-1 for P. chlamydosporia var. catenulata or applied at different times of treatment.
