Short note on the effects of ethanolic extracts of selected South African seaweeds on the growth of commercially important plant pathogens, Rhizoctonia solani Kühn and Verticillium sp.

Antimicrobial activity ofAlepidea amatymbica

“…The prepared plates containing the extracts were inoculated with plugs obtained from actively growing portions of the mother fungal plates and incubated at 25°C for five days. Diameter of the fungal growth was measured and expressed as percentage growth inhibition of three replicates (Afolayan & Mayer, 1997;Barreto et al, 1997;Quiroga et al, 2001). Significant differences within the means of treatments and controls were calculated using the LSD statistical test as described by Steel and Torrie (1960).…”

Antimicrobial activity ofHippobromus pauciflorus: A medicinal plant used for the treatment of eye infections in the Eastern Cape, South Africa

“…The prepared plates were inoculated with plugs (5 mm in diameter) obtained from the actively growing portions of the mother fungal plates and incubated at 25°C for 5 days. The diameter of fungal growth was measured and expressed as percentage growth inhibition of three replicates (Barreto et al, 1997;Quiroga et al, 2001;Lewu et al, 2006;Koduru et al, 2006). Due to the nature of C. albicans, the organism was streaked radially like the bacteria.…”

Antimicrobial activity ofHermannia incana

“…Due to the nature of Candida albicans, the organism was streaked radially like the bacteria. The diameter of fungi growth was measured and expressed as percentage growth inhibition of three replicates (Afolayan & Meyer, 1997;Barreto et al, 1997;Quiroga et al, 2001).
