摘要
金叶女贞在 6 - 7月和 9- 10月间大量落叶 ,研究结果表明系叶片上发生叶斑病所致 ,其中一种为假尾孢菌 .该菌的分生孢子宽为 7.1- 9.6 μm ,明显不同于已报道过的发生在木犀科中 7种假尾孢菌 ,在发病初期连续 3次喷施多菌灵、甲基托布津 ,可有效地控制叶斑病发生为害 .
The research results showed that the leaf-spot of California Privet was caused by Pseudocercospore sp. The conidia of pathogone,7.1～9.4μm in width,is different from the known Pseudocercospore spp.in Oleaceae.The disease can be controlled effectively by spraying Batristin or Topsim-M three times in succession at the early stage of the disease.
