摘要
通过室内苗期和成株期田间小区试验,测定了不同浓度的Folicur和Caramba对小麦白粉病的防治效果。结果表明,苗期1.15mL/L的Folicur,3.75mL/L的Caramba对小麦叶片具有很好的保护作用,对已发病的小麦叶片能够抑制叶片内病菌的生长。成株期发病前施药,Folicur和Caramba对小麦白粉病的防治效果分别为86.57%和82.09%,均高于常规用量粉锈宁的防治效果(68.16%);发病后用药,防治效果可达68%以上,仍高于常规用量粉锈宁的防治效果(65.74%)。
The control effects of Folicur and Caramba of different concentrations against wheat powdery mildew were tested by greenhouse and field. The result of seedling test showed that Folicur (1. 15 mL/L),Caramba (3.75 mL/L) had better protection. They could inhibite the fungi growth in the diseased wheat leaves. The result of field test showed that the control effect of Folicur and Caramba were 86.57% and 82. 09% and higher than that of triadimefon (68. 16) when spraying fungicide before the powdery mildew occurred. The control effects were still over 68% and higher than that of triadmefon when spraying fungicide after the disease happened.
