“药肥组合”对乌药白绢病的防治效果及产量影响研究

摘要

为了筛选乌药白绢病防病增产的最佳“药肥组合”,指导大面积防治,选用24％噻呋酰胺悬浮剂等5种杀菌剂以及叶面肥金钾(N10％、P2O515％、K2O30％及微量元素)进行田间药效对比试验.结果表明,30％甲霜·恶霉灵水剂+金钾对乌药白绢病的防效达63.29％,无论是速效性还是持效期均优于其他供试药剂,增产幅度大,增幅达27.53％.%In order to screen out the optimum recipe of fungicide-fertilizer combination to control southern blight of Lindera aggregate,and provide the guidance for the large-scale control of the disease in the field,the efficacy of trifluzamide 24％ SC and the other 4 fungicides in combination with foliar-fertilizer gold potassium (10％ N,15％ P2O5,30％ K2O and microelement) were studied and compared.The results indicated that the combination of metalaxyl · hymexazol 30％ AS and gold potassium provided the best efficacy of 63.29％,was superior to the other fungicide-fertilizer combinations in both terms of efficiency and persistence,and increased the yield by 27.53％.
