wilt of potato is one of the most common diseases of potato in China, and is becoming a serious threat in potato production. It has been reported that osthole from () can inhibit plant pathogens. Here, we test the anti-fungal activity of osthole against in potatoes. The results showed that at a concentration of 5 mg/mL, osthole was able to obviously inhibit mycelial growth of . We found that osthole caused changes of mycelial morphology, notably hyphal swelling and darkening. Osthole significantly reduced the spore germination of by 57.40%. In addition, osthole also inhibited the growth of other pathogens such as J. Sheld, Donk, and (Fr.) Keissl, but not Jonesetgrout and Miyabe and G. Yamada. Our results suggest that osthole has considerable potential as an agent for the prevention and treatment of potato wilt.
马铃薯早疫病是中国马铃薯最常见的病害之一，正在成为马铃薯生产的严重威胁。据报道，蛇床子素（）可以抑制植物病原体。在这里，我们测试了蛇床子素对马铃薯中致病疫霉的抗真菌活性。结果表明，在 5mg/mL 的浓度下，蛇床子素能够明显抑制致病疫霉菌丝的生长。我们发现蛇床子素导致菌丝形态发生变化，特别是菌丝肿胀和变黑。蛇床子素显著降低了致病疫霉孢子的萌发率达 57.40%。此外，蛇床子素还抑制了其他病原体如茄链格孢、链格孢和（细极链格孢）的生长，但对琼斯霉和米耶黑霉和山田氏丝核菌无效。我们的结果表明，蛇床子素具有作为防治马铃薯早疫病的药剂的巨大潜力。
