Antifungal efficacy of Capsicum frutescens L. extracts against some prevalent fungal strains associated with groundnut storage

چکیده
The antifungal potential of aqueous leaf and fruit extracts of Capsicum frutescens against four major fungal strains associated with groundnut storage was evaluated. These seed-borne fungi, namely Aspergillus flavus, A. niger, Penicillium sp. and Rhizopus sp. were isolated by standard agar plate method and identified by macroscopic and microscopic features. The minimum inhibitory concentrations (MIC) and minimum fungicidal concentration (MFC) of C. frutescens extracts were determined. MIC values of the fruit extract were lower compared to the leaf extract. At MIC, leaf extract showed strong activity against A. flavus (88.06%), while fruit extract against A. niger (88.33%) in the well diffusion method. Groundnut seeds treated with C.frutescens fruit extract (10mg/ml) showed a higher rate of fungal inhibition. The present results suggest that groundnuts treated with C. frutescens fruit extracts are capable of preventing fungal infection to a certain extent.

BACKGROUND The continuous spread of multidrug-resistant (MDR) bacteria, partially due to efflux pumps drastically reduced the efficacy of the antibiotic armory, increasing the frequency of therapeutic failure. The search for new compounds to potentiate the efficacy of commonly used antibiotics is therefore important. The present study was designed to evaluate the ability of the methanol extract...

Endophytic bacteria which show antagonism against phytopathogens were isolated from healthy tissues of leaves, stems and roots of chili pepper plants (Capsicum annum L.) in 2010-2011. Antifungal activities of all collected isolates were tested against plant pathogens by dual culture method. Pathogenic fungi used in this study were Alternaria panax, Botrytis cinerea, Colletrotichum acutatum, Fus...
