香茅醇不同旋光异构体对抑制茶炭疽病病菌活性的比较及其协同作用
Fungicidal Activity Comparison and Synergetic Effect of Citronellol Optical Isomers Against Colletotrichum gloeosporioides
摘要
Abstract
In this study, the activities of dextral citronellol, rhodinol and their synergistic effect to the C. gloeosporioides was determined by method of mycelial growth rate, Horsfall and co-toxicity coefficient. The EC50 of dextral citronellol and rhodinol were (113.27±0.95) mg·L-1 and (119.87±0.20) mg·L-1 respectively. The dextral citronellol and rhodinol were mixed according to the mass ratio. The result shows that the synergistic effect was the highest with the co-toxicity coefficient of 130.19 under the mass ratio of 1.6︰1 (dextral citronellol︰rhodinol). The co-toxicity coefficients were 120.57 and 121.42 when the mass ratio were 1︰1.4 and 1︰3.8, respectively. The results indicate that citronellol and its two optical isomers had high inhibiting activities against C. gloeosporioides, and the synergistic effect could be performed by mixing them within certain proportion.关键词
