Selection of response variable to determine the sensitivity of Alternaria spp isolates to Boscalid

Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

The present study aimed to check the application of different variables to determine the sensitivity of isolates of Alternaria spp. to the fungicide boscalid. The tested variables were mycelial growth inhibition (MGI), minimum inhibitory concentration (MIC) and inhibitory concentration at 50% (IC50). Only the variable IC50, from regression analysis, was capable of discriminating the difference in sensitivity of the isolates obtained from different cultures. Thus, it is the most recommended variable for studies with the pathogen.
