CL50 and pathogenic power of Beauveria bassiana and Metharizium anisopliae isolates infectingPremnotrypes vorax populationsCL50 y variación de la patogenicidad en aislamientos de Beauveria bassiana y Metarhizium anisopliae evaluados en poblaciones de Premnotrypes vorax
(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2003)
In order to evaluate an “ecologic” alternative for the control of the white worm potato (Premnotrypes vorax), were studied six Beauveria bassiana and one of Metharizium anisopliae isolates, native of Nariño, Colombia.Their pathogenicity and variability were observed under laboratory conditions using a concentration of 1x107 spores.ml-1. All the biocontrol densities evaluated were pathogenic to P. vorax; however, there ...
