两种毛壳菌对几种植物病原菌的生防效果分析

Study on analysis of biological control effect of two kinds of Chaetomium spp.on several pathogen

将角毛壳菌和球毛壳菌与立枯丝核菌等5种植物病原菌进行对峙试验,结果表明,球毛壳菌和角毛壳菌对几种病原菌的抑制作用明显.球毛壳菌主要通过竞争作用、重寄生作用抑制病原菌,角毛壳菌主要通过产生红色拮抗物质、竞争作用抑制病原菌的生长.

C. cupreum and C. globosum are tested by dual culture with Rhizotonia solani and five other plant pathogens. The result shows that C. cupreum and C. globosum have strong inhibition to these pathogens. The main control mechanism of C. globosum is competition and mycoparasitism. The main control mechanism of C. cupreum is producting red antibiotics and competition.
