Water or ethanol extracts of common pink and common white garlic varieties were tested at a concentration of 250 ppm while sterile distilled water served as control. In vivo study was based on white garlic extracted alone at 0.50 and 100% concentrations on M.phaseolina and C.capsici. Data were subjected to ANOVA and means was separated at P=0.05. Water extracted white garlic gave over 90% inhibitions of mycelial growth of M. Phaseolina and gave higher inhibitions than water or ethanolic pink garlic extracts on all the three pathogens. It is not significantly lower P=0.05 than conventional fungicide benomyl at 0.05 gai/kg. However, in vivo result was phytotoxic to cowpea seeds at 100% concentration and pathogrn control at 50% garlic extract. In contrast, cowpea variety IT84S-2246-4 seed germination was 77% when treated with M.phaseolina and 100% with C.capsici but reduced pathogen control at 50% garlic extracten-USPink and white garlicFungal pathogensConventional fungicideCowpea varietiesGerminationPhytotoxicityControlArticle
