Abstract

The aim of present research was focused on the antifungal activities of Prunella vulgaris L and Paeonia suffruticosa Andrews via in vitro approach through agar well diffusion assay at three concentrations (25 uL, 50 uL and 75 uL) against fungi causing diseases in tomato and brinjal. All the concentration of plant extracts showed antimycotic activity against tested pathogenic fungi. Antimycotic activity increased with the increased concentrations of plant extracts. However, higher concentrations proved more effective than lower concentrations. It was revealed from the present study that the ethanolic and aqueous extracts of Prunella vulgaris L showed maximum antimycotic activity against Rhizoctonia solani and least inhibitory effect against Penicillium chrysogenum. It was further revealed from the present study that the ethanolic extract of Paeonia suffruticosa Andrews showed maximum antimycotic activity against Penicillium expansum and least activity against Mucor plumbeus. Whereas the aqueous extract of Paeonia suffruticosa Andrews showed maximum antimycotic activity against Rhizoctonia solani and Penicllium expansum and least inhibitory effect against Mucor plumbeus.

不同植物提取物对克什米尔谷地番茄和茄子真菌腐病防治效果的评价

采用琼脂孔扩散法研究了夏枯草(Prunella vulgaris L)和芍药(Paeonia suffruticosa Andrews)在25、50和75 uL浓度下对番茄和茄子病原菌的抑菌活性。所有浓度的植物提取物均表现出抗真菌活性。抗真菌活性随植物提取物浓度的增加而增加。然而，较高的浓度证明比较低的浓度更有效。结果表明，夏枯草醇提液和水提液对茄枯丝核菌的抑菌活性最高，对青霉菌的抑菌活性最低。结果表明，牡丹醇提物对膨胀青霉的抑菌活性最高，对铅毛霉的抑菌活性最低。赤芍水提物对茄枯丝核菌和扩张青霉的抑菌活性最高，对铅毛霉的抑菌活性最低。
