Fungicidal control of two pathogenic fungi of Parkia biglobosa (Jacq) benth

Abstract

The efficacy of two fungicides, Benlate and Thiram were evaluated in vitro against Aspergillus tamarii and Corynespora cassiicolla, two fungi isolated from the seeds and leaf-spot of Parkia biglobossa. The fungicides were tested at four concentrations of 0.1, 1.0, 10 and 100 ppm impregnated into Potato Dextrose Agar (PDA). The radial growths of the fungi on PDA were compared. Analysis of variance was done on the data and the means were separated with LSD. Benlate was found to be superior to Thiram as it suppressed the growth of both fungi at 10ppm.

Key words: Fungicides, pathogenicity, Parkia biglobossa, Corynespora cassiicola, Aspergillus tamarii
