Behavior of fungus Rhizoctonia solani under faba bean cotyledons when away from host and the effect of its starvation on aggressiveness

Behavior of Rhizoctonia solani on their hosts was carried out-in many studies when the pathogen was in close proximity with its host. The purpose of this study was focused on the behavior of this fungus on faba bean cotyledons when it was away from the host and the effect of nutritional status on its pathogenicity was also taken into consideration. Observations led to speculation that R. solani feels its host even when...

Identification of micro-organisms associated with jatropha curcas and inhibition by selected natural plants extracts

Studies were carried out to determine the microorganisms associated with Jatropha curcas and the effect of selected botanicals crude extracts (bitter leaf: Vernonia amygdalina and Uziza leaf: Piper guineensis) on the inhibition of these microorganisms. The experiment comprised three extract concentrations 20, 30 and 50% and was carried out in a completely randomized design with six replications. Results show that only...
