Abstract
Benzimidazole resistance in thirty isolates of the biocontrol agents was studied with reference to specific mutations in the β-tubulin genes. Our results suggest that apart from the correlation between specific mutations in the β-tubulin gene and variation in resistance, the overall ratio of polar and non-polar amino-acids may also play a vital role in conferring benzamidazole resistance to these fungi.
Keywords: biocontrol agents, benzamidazole, non-polar amino acids, polar amino acids
