5种表面活性剂对铜制剂防治冰糖橙溃疡病效果的影响

Influences of Five Surface Active Agents on Control Effect of Copper Fungicides to Citrus Canker Disease of Bingtang Sweet Orange

柑橘溃疡病是一种世界性的检疫病害,柑橘感病后不仅影响树势生长,而且降低果实商品价值。比较了5种活性剂对铜制剂防治冰糖橙溃疡病的效果,结果表明:斯巴坦农用渗透剂对铜制剂能起到较好的增效作用,部分新梢防效与可杀得(对照2)达到了显著差异,并能控制果实病情指数始终不再增长,防止溃疡病上果;动力农用有机硅助剂和不怕水高效润湿展着剂对铜制剂防效无影响;捷润农用助渗剂和水助农用有机硅水调节剂则显著降低了铜制剂的防效。

As a worldwide quarantine disease, citrus canker will make a great impact on the growth of tree vigor and reduce the commodity value of citrus fruit. In order to increase the prevention effect of citrus canker, the effects of five active agents on controlling citrus canker by copper fungicides were compared. The results showed that “spartan” had relatively better synergism for copper fungicides; the control effect on partial new shoots between it and “Kocide” （control 2） reached a significant difference; it can stop the increase of fruit disease index, thus preventing fruit infected by citrus canker. “Kinetic” and ,Surfix“ showed no influence on control efficiency of copper fungicides;“Jierun” and “Interactive” significantly reduced the control effect of copper fungicides,
