ABSTRACT

To help find alternative control methods against seed-borne microorganisms, a study was undertaken to evaluate the antifungal activity of three plant extracts on rice, maize, cowpea and groundnut seeds. . To this end, the efficacy of the hydroalcoholic extracts of Hyptis suaveolens, Western Anacardium and Azadirachta indica was measured on the fungi Aspergillus flavus, Aspergillus niger, Alternaria padwickii and Fusarium moniliforme of the studied seeds. Sanitary tests of the infected seeds were carried out by the paper method after being soaked in hydroalcoholic extracts. Then, the effect of these extracts on the germination rate of the treated seeds was evaluated by the method of between papers. This study shows that the three extracts reduce or inhibit differently the infection rate of fungi found on seeds.

Keywords: antifungal activity, hydroalcoholic extracts, seeds, fungi.
