摘要
在室内测试了20种植物提取物对马铃薯晚疫病菌的抑菌作用,结果表明9种植物提取物对 孢子囊萌发具有显著的抑制作用,6种植物提取物对孢子囊产生具有显著的抑制作用。其中Ts-86、 Ts-39、Ts-109和Ts-121四种提取物抑菌效果与化学药剂“Ridomil”3000倍达到同一显著水平,并对 其进行了进一步测试。结果表明,Ts-86对马铃薯晚疫病菌产孢及孢子囊萌发的抑制效果显著优于另 外3种提取物,与“Ridomil”3000倍达到同一显著水平。
Twenty species of plant extracts were tested for their fungitoxity against Phytophthora infestans in this study. Preliminary results showed that 9 of 20 plant extracts showed significant inhibitory effects on sporangia germination and 6 of 20 plant extracts showed significant inhibitory effects sporangia forming of P. infestans. Four species of the plant extracts including Ts-86, Ts-39, Ts-109 and Ts-121 showed equivalent strong inhibitory effects with the chemical control-“Ridomil” 3000 times dilution were further tested on slides for their inhibitory effects on sporangia germination and production of P. infestans. The extract Ts-86 showed equivalent strong inhibitory effects with the chemical control-“ Ridomil” 3000 times dilution, and significantly stronger than the other three extracts.
