Inhibition of Plant Extracts to Four Kinds of Pathogenetic Fungi

The studies on the inhibition of 8 kinds of plant extracs to the growth and sprout rate of Alternaria brassicae,Fusariam oxysporum, Colletotrichum lagenarium and Alternaria solani,showed that the extracts of Wedelia chinensis, Capsicum annuum and Manilkara zapota had more obvious inhibition to growth,the pathogenetic fungi,with the repression rate being 39.19%, 36.54%, 44.18% resp.the tentracts of Portulara oleracea,W.and C.were more distinct to sprout rate the pathogenetic fungi,with the remession rate being 24.72%,29.45%,41.74%,resp.P.,W.and Pesidium guajava were more distinct to expend the pathogenetic fungi,wirh the repression rate being 42.17%,39.50%, 36.93% resp..
