ResumoThe natural quinones lapachol, α-lapachone and β-lapachone, and the synthetic derivative β-lapachone-3-sulfonic-acid were assayed for inhibition of fungal growth (Fusarium oxysporum) and germination of lettuce seeds (Lactuca sativa L.).β-Lapachone has the strongest activity as a germination inhibitor and lapachol shows no effect.β-Lapachone, followed by lapachol, are the most active in reducing fungal growth.
