多裂骆驼蓬提取液的抑菌杀虫作用研究

Studies on the Inhibition and Disinsection of Fungistatic Agent Extracted from Peganum multisectum Bobr

多裂骆驼蓬(PeganummultisectumBobr)系蒺藜科的一种多年生草本植物,其种子的乙醇提取物对供试的3种植物病菌有较好的抑菌活性。其中对小麦锈菌抑制活性最显著,其孢子的校正抑制率达78%。对蚜虫的室内毒力测定发现对桃粉蚜(AppeugschwartziBorner)、桃蚜(Myzuspersicae)、麦二叉蚜(SchizaphisgavminunRondin)有明显的触杀活性。

Peganum multisectum Bobr is a perennial herb of ygophyllaceae. It is found in the bioassay that the fungistatic agent of the alcoholic extracted from the seed of Peganum multisectum had a remarkable impact and disinsection on plant pathogenic fungi and Aphids, especially on Puccinia glumarum Erikss,Appeug schwartzi Borner, Myzus persicae,Schizaphis gav-minum Rondin.
