| 摘 要： | 为了减少化学杀菌剂在田间的使用,提高对山核桃干腐病(Botryosphaeria dothidea)的防治效果,选用植物源农药苦参碱与8种化学杀菌剂进行复配。采用生长速率法测定杀菌剂对山核桃干腐病的抑菌效果。通过共毒因子法定性分析筛选发现,苦参碱与甲基托布津和嘧菌酯复配效果最好。结合各杀菌剂EC50值,最终选取抑菌效果较好的甲基托布津与苦参碱进行复配。利用共毒系数法定量分析发现,当苦参碱与甲基托布津复配比例为5∶5和6∶4时,其共毒系数值分别为197.605和186.257,增效作用显著,对山核桃干腐病抑菌效果明显优于单剂使用。

| Abstract: | The antifungal and synergistic effects of matrine compound with eight different chemical fungicides against Botryospha-eria dothidea were determined by the growth rate method to reduce the use of pesticides and increase the control effect.The matrine and thiophanate-methyl/azoxystrobin mixtures were screened as the better combinations by co-toxicity factor meth-od, nevertheless, azoxystrobin was eliminated due to the lower antifungal activity than thiophanate-methyl against B.do-thidea.Matrine and thiophanate-methyl with ratio of 5 :5 and 6 :4 showed higher co-toxicity coefficient of 197.605 and 186.257, respectively.Therefore, the synergistic effects of matrine combined with thiophanate-methyl was obviously higher than the single-dose use. |
