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.
