The inhibition effects of ten eugenol derivatives against Fusarium graminearum Q1 strain were determined using the mycelia growth rate process. Our results revealed that the toxicities of various derivatives differed substantially as compared to that of eugenol. Isoeugenol had the highest toxicity, about 4.2 times that of eugenol, with the EC₅₀ value of 279.7 µM. Based on the toxicity ratio (TR) and synergistic coefficient (SR), the optimum mixing mass ratios of isoeugenol to phenamacril and isoeugenol to tebuconazole against F. graminearum were 7:1 and 6:1, respectively. Based on their additive effects, these mixtures could be used as potential alternatives to control F. graminearum resistance against phenamacril and tebuconazole due to different mechanism of action.

采用菌丝体生长速率法测定了十种丁香酚衍生物对禾谷镰刀菌Q1 菌株的抑制作用。我们的结果表明，与丁香酚相比，各种衍生物的毒性有很大差异。异丁香酚的毒性最高，约为丁香酚的 4.2 倍，EC ₅₀值为 279.7 µM。基于该毒性比（TR）和增效系数（SR），最佳混合的质量比异丁子香酚以phenamacril和异丁子香酚，以针对戊唑醇禾谷镰刀菌分别为7：1和6：1，分别。基于它们的累加效应，这些混合物可用作控制禾谷镰刀菌的潜在替代品 由于作用机制不同，对非那克林和戊唑醇的耐药性。
