摘　　要：40%咪铜·氟环唑SC是新登记的防治小麦赤霉病的复配杀菌剂,具有广谱性高、对小麦生长安全等特点。为验证40%咪铜·氟环唑SC对小麦赤霉病、条锈病、叶锈病的防治效果,开展大田防治试验,调查450、600、750 mL/hm^(2)40%咪铜·氟环唑SC,375 mL/hm^(2)45%戊唑·咪鲜胺EW(对照药剂)及空白对照(CK)处理小麦赤霉病、条锈病、叶锈病的发病情况及产量。结果表明,不同施用量的40%咪铜·氟环唑SC处理小麦正常成熟不早衰,叶片和穗颜色鲜黄不发暗。40%咪铜·氟环唑SC对赤霉病、条锈病、叶锈病的防治效果较好,病情指数均低于CK和对照药剂;防效分别为89.36%~92.55%、89.74%~94.87%、85.97%~89.09%,防效随着40%咪铜·氟环唑SC施用量的升高而升高,且防效均高于对照药剂。40%咪铜·氟环唑SC处理小麦产量为8283.35~8419.99 kg/hm^(2),且产量随着40%咪铜·氟环唑SC施用量的增加而增加,产量高于对照药剂和CK,较CK增产12.088%~13.938%。As a newly registered compound fungicide for the control of wheat Fusarium head blight(FHB),40%imidcopper·flucyclozole SC has the characteristics of high spectrum and safety for wheat growth.In order to verify the control effect of 40%imidcopper·fluocyclozole SC on wheat FHB,stripe rust and leaf rust,field control test was carried out to investigate the effect of 450,600,750 mL/ha 40%imidcopper·fluocyclozole SC,375 mL/ha 45%pentazole·imidazole EW(control agent)and blank control(CK)on control of wheat FHB,stripe rust,leaf rust and yield.The results showed that the wheat with different amount of 40%imidcopper·flucyclozole SC normally ripened without premature aging,and the color of leaves and ears was bright yellow without darkening.The control effects of 40%imidcopper·fluocyclozole SC on FHB,stripe rust and leaf rust were better,and the disease indexes were lower than CK and control agent.The control effects were 89.36%—92.55%,89.74%—94.87%and 85.97%—89.09%,respectively.The control effects increased with the increase of amount of 40%imidcopper·fluocyclozole SC,and the control effects were higher than that of the control agent.The yield of wheat treated with 40%imidcopper·fluocyclozole SC was 8283.35—8419.99 kg/ha,and increased with the increase of amount of 40%imidcopper·fluocyclozole SC,which was higher than thoes of control agent and CK,with 12.088%—13.938%higher than that of CK.
