a causal agent of soybean rust disease was studied. Both
methanolic and n-hexane crude extracts inhibited spore germination at concentrations of 0.1% to 5.0%.
Methanolic extract of the roots at a concentration of 2.5% inhibited 55% of spore germination, and this
result was similar when higher concentration at 5% of methanolic and n-hexane extracts of the flowers
was used. The presence of alkaloids, flavonoids, tannins, saponins, and terpenoids in the extract may be
responsible for the inhibition. The extract was potential to be utilized as a botanical fungicide.
