合成杀菌剂的使用需要逐步减少，因为它对人类健康和环境有不利影响。将杀真菌剂与生物防治剂（BCA）相结合的综合方法可用于减少杀真菌剂剂量，从而最大限度地减少与化学杀真菌剂相关的风险。在这项研究中，BCA木霉菌和杀菌剂恶霉灵的组合应用，以管理豇豆枯萎病引起的尖孢镰刀菌。筛选出一株对恶霉灵具有抗性的木霉菌株SC 012，经鉴定为T.棘孢菌属T. asperellum SC 012对F.在添加或未添加恶霉灵的培养基上，均能穿透并包围病原菌菌丝。当与恶霉灵配合使用时，木霉菌在豇豆根际土壤中的种群密度与单独使用木霉菌的处理相比没有显著差异。当T.单用腐霉唑和单用腐霉唑的防治效果均比单用腐霉唑和腐霉唑的防治效果好。结果表明，木霉菌与恶霉灵的组合可减少化学杀菌剂的使用，具有生态友好性，可作为豇豆枯萎病综合防治的重要组成部分。
The use of synthetic fungicide needs to be gradually reduced because of its adverse effect on human health and the environment. An integrated approach combining fungicides with biological control agents (BCAs) can be used to reduce the fungicide doses, thereby minimizing the risks associated with chemical fungicides. In this study, the combined application of a BCA Trichoderma and a fungicide hymexazol was used to manage the cowpea wilt disease caused by Fusarium oxysporum. The Trichoderma SC012 strain, which is resistant to hymexazol, was screened out and identified as T. asperellum. T. asperellum SC012 showed hyperparasitism to F. oxysporum and could penetrate and encircle the hyphae of pathogen on a medium amended or not with hymexazol. When combined with hymexazol, the population density in the rhizosphere soil of cowpea showed no significant difference compared with the treatment Trichoderma used alone. When the concentration of T. asperellum SC012 or hymexazol was halved, their combined application could control cowpea wilt disease more effectively than their individual use. The findings showed that the combination of Trichoderma and hymexazol could reduce the use of chemical fungicide, which is eco-friendly and may be an important part of integrated control of Fusarium wilt in cowpea.
