摘要

由Rhizoctonia solani引起之菠菜病害，可造成種子不發芽，苗期之猝倒，中期植株之立枯及採收時之冠腐。供試16種藥劑，分成種子藥劑處理及土壤噴施藥劑處理，首先由實驗室篩選有效之藥劑，供溫室試驗，最後於田間進行藥效比較，結果同一種藥劑在種子處理及土壤施藥處理上對苗期之防治效果相近，皆優於對照不施藥區，但於菠菜採收時種子處理者冠腐發生率較土壤施藥者高。藥劑中以50%脫克松可濕性粉劑1,000倍、50%福多寧可濕性粉劑3,000倍及25%賓克隆可濕性粉劑1,000倍防病效果最好。

Seed treatment and soil drench were used for screening chemicals that inhibiting Rhizoctonia diseases of spinach. In the laboratory and greenhouse tests, Tolclofos methyl, Flutolanil, Iprodione, and Pencycuron were better than other chemicals in these two treatments. Furthermore, two trials in the field, Tolclofos methyl, Flutolanil and Pencycuron were the most effective with the soil drench had better result than the seed treatment for control the Rhizoctonia diseases of spinach.
