Abstract

The invention discloses an application of asarum caulescens and extract thereof in preventing and treating plant pathogenic fungi. The application comprises the following steps: soaking the asarum caulescens with methanol, extracting the asarum caulescens methanol extract with petroleum ether and ethyl acetate, and detecting the bacteriostatic activity of each phase extract of the asarum caulescens . Research finds that the asarum caulescens methanol extract has an obvious inhibiting effect on mycelial growth of 12 plant pathogenic fungi including pyricularia oryzae, hylocereus undatus alternaria brassicae,Colletotrichum musae, mango colletotrichum gloeosporioides, wheat scab, Macrophoma kawatsukai, Alternaria solani, Phomopsis mangiferae, and Fusarium oxysporum. Therefore, the asarum caulescens methanol extract has a certain broad-spectrum inhibition effect on pathogenic fungi, and has the potential of being developed into a botanical bactericide.

Description

technical field [0001] The invention belongs to the field of plants, and in particular relates to the application of Asarum futifae and its extract in preventing and treating plant pathogenic fungi. Background technique [0002] Asarum, as a traditional Chinese medicine, has the effects of relieving the exterior and dispelling cold, dispelling wind and relieving pain, clearing the orifices and warming the lungs and transforming drink. Symptoms such as phlegm retention, dyspnea and cough. Among the many plants of the genus Asarum, Asarum heterotropoides Fr. Schmidtvar. mandshuricum (Maxim.) Kitag and Asarum sieboldii Miq.i are mainly used as the dried whole herb of Asarum asarum. Studies have reported that the ethanol extract of Liaoshixin has good anti-inflammatory activity in vitro. In terms of agricultural control, Liu Nannan and others found that the essential oil of Liaoshixin has a certain antibacterial effect on melon fruit spot bacteria. Liu Haiyan et al. found tha...
