摘要
叶青双经先照处理2—16h后,对水稻白叶枯病的活性显著增强。接菌前1天和接菌当时施药,第10天的抑病效果>80%,接菌后1天施药,第15天的抑病效果达60%左右,说明光产物不仅有很好的保护作用,叶片内吸后的治疗作用比母体显著增强。光产物叶面施用的残效期比母体延长5—7天;根部内吸作用良好,根施10天后抑病效果达90%左右。光产物溶液经1年黑暗贮存后仍具有稳定的活性。
The bacteriostic activity of photodecomposite product of Yeqingshuang on rice bacterialblight was investigated.The control effect against rice bacterial blight of the photoproductswas much more superior to that of Yeqingshuang.With better root systemic action,longerresidual effect and stronger curative activity,the photoproducts was proved to be a hopefulnew bactericide against this rice disease.
