Characterization of Rhizoctonia solani associated with sore shin and leaf spot symptoms on tobacco in Zimbabwe



Characterization of Rhizoctonia solani associated with sore shin and leaf spot symptoms on tobacco in Zimbabwe



Journal of Phytopathology 140(4): 367-374



The relationship between R. solani isolates derived from leaf spot and sore shin symptoms on tobacco was characterized by determining nuclear number, hyphal diam., anastomosis group (AG) and pathogenicity. The leaf spot isolates had significantly more nuclei per cell, and wider hyphae than the sore shin isolates. Anastomosis pairings with known tester strains confirmed the leaf spot isolates to be AG 3 and the sore shin isolates to be AG 4.
