小麦条锈病是小麦生产中的重要病害之一,为了明确中草药苍耳和黄瑞香提取液对小麦条锈病的抑制作用,分别以两种中药水浸液测定其对小麦条锈病菌的抑制作用,以及对小麦条锈病的防治效果。结果显示,不同浓度的苍耳、黄瑞香提取液对小麦条锈菌孢子萌发和菌丝生长均有抑制作用,在浓度为0.50 g/mL条件下对其孢子的萌发抑制率分别为69.29%和64.44%,对其菌丝生长的抑制率分别为55.44%和44.77%。两种中药浸提液叶面喷施试验结果显示,两种中药浸提液对小麦条锈病都具有显著的防治效果。
Wheat stripe rust is one of the most damaging wheat plant diseases. In this study, different concentration gradients of Daphne giraldii nitsche and Siberian Coeklebu:Fruit extracts were used to control rust sporangium germination and mycelial growth. The results showed that two kinds of herbal medicine aqueous extract inhibited the growth of sporangium germination and mycelia of rust. With 0.50 g/mL concentration of Daphne giraldii nitsche and Siberian Coeklebu: Fruit, inhibiting rates of wheat stripe rust spore germination were 69.29% and 64.44%, and inhibiting rates of mycelial growth were 5.44% and 44.77%, respectively. In conclusion, the study demonstrated that spraying these two kinds of herbal medicine aqueous extracts had significant preventive effect on stripe rust fungi at both seedling and maturity stages.
