“药肥组合”对乌药白绢病的防治效果及产量影响研究

Study on the Efficacy and Effect on Yield of Fungicide-fertilizer Combination against Southern Blight on Lindera aggregate

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%、P_2O_515%、K_2O_30%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 southern blight of Lindera aggregate, and provid cipe e the disease in the field, the efficacy of trifluzamide 24% with foliar - fertilizer gold potassium （ 10% N, 15% studied and gol guidance for the large -scale control SC and the other 4 fungicides in co P205, 30% K20 and and compared. The results indicated that the combination of metalaxyl · d potassium tilizer combinations control of the microelement ） hymexazol 30 provided the best efficacy of 63.29% , was superior to the other fungicide in both terms of efficiency and persistence, and increased the yield by 27. were % AS -- fer- 53%.
