GONZALEZ, E  e  MORAIMA, Surís. In vitro SELECTION OF PROMISSORY STRAINS OF Lecanicillium lecanii (ZARE AND GAMS) FOR THE BIOLOGICAL CONTROL OF Hemileia vastatrix (BERK. et Br.). Rev. Protección Veg. [online]. 2007, vol.22, n.2, pp. 128-130. ISSN 2224-4697.

The heuristic method determining the weight of the biological and physiological values of each isolate was used to select promissory strains of Lecanicillium lecanii (Zare and Gams) as biological control agents. The target pest was Hemileia vastatrix (Berk. et Br.) causal agent of coffee rust. This novel method in this type of study permitted the selection of V1-01 as the isolate with the best attributes according to its mycelium growth on different culture media at the temperature and relative humidity values studied, better sporulation on solid media, higher percentages of parasitism and deformation of the phytopathogen uredospores resulting successful as a tool of analysis for selection.
