摘要
对贵州省中药材续随子病害进行了调查和病原鉴定。结果表明:续随子立枯病病原由镰刀菌引起。对其选用了4种杀菌剂进行室内活性测定,其中,3%广枯灵AS对续随子立枯病菌丝生长的抑制活性最强,500μg/mL时抑制率为96%,EC50值为20.5μg/mL。
Diseases investigation and the pathogen identification of Euphorbia lathyris L. were carried out in Guizhou. The results show that the seedling blight caused by Fusarium spp. was the main fungal disease of E. lathyris. Four fungicides were applied to test their pathogenicity indoor. It is found that the myeelia growth of Fusarium spp. is strongly inhibited by 3% Guangkuling AS with inhibition rate of 96% at 500μg/mL concentration, and the EC50 value is 20.5μg/mL.
