摘  要:
[目的]明确烯肟菌酯和丙硫菌唑混剂在防治农业病害上的可混性。[方法]进行室内联合毒力试验和田间药效试验。[结果]烯肟菌酯与丙硫菌唑混配,对禾谷类多种病害具有良好的抑制效果,多个混配比例共毒系数均大于120,表现为增效作用。在112.5、135 g a.i./hm~2剂量下,25%烯肟菌酯·丙硫菌唑悬浮剂对小麦赤霉病、白粉病、锈病的防治效果高于对照药剂40%多·酮可湿性粉剂、40%戊唑·多菌灵悬浮剂和25%氰烯菌酯悬浮剂的药效。[结论]烯肟菌酯与丙硫菌唑混剂对小麦多种病害均有较好的防治效果,在小麦病害的综合防治上具有很好的应用前景。

摘  要:
[Aims] This study aims to confirm the miscibility of enestroburin and prothioconazole against crop disease.[Methods] The synergistic action test and field trials were carried out. [Results] The results showed that the co-toxicityindexes of several mixtures were up to 120. They were all synergistic effect against cereal disease. At the dosages of 112.5 and 135 g a.i./ha, the efficacy of enestroburin and prothioconazole 25% SC was better than carbendazim and triadimefon 40% WP, tebuconazole and carbendazim 40% SC and JS399-19 25% SC against fusarium head blight, rust and powdery mildew of wheat in field trails. [Conclusions] The mixture of enestroburin and prothioconazole offered perfect efficacy against several diseases of wheat and would have good application prospect in comprehensive control of wheat disease.
