摘要
油菜菌核病叶病株在盛花期(3月1日左右)、茎病株在终花前后(3月20日左右)开始大量出现。在供试10个品种中,以821,杂2-4较抗耐病,栽植密度以12株/m2为宜。用多菌灵。
Leaf rot and stem rot caused by Sclerotinia sclerotiorum (Lib.) de Bary in rapeseed crops were found to be widespread at full bloom (around March 1) and final bloom (around March 20) stages, respectively. Of the 10 rapeseed cultivars studied, Zhong You 821 and Zai 2~4 appeared comparatively tolerant to the disease. A population density of 12 plants per m 2 is recommended. A spray of Carbendazim, Thiophanate methy or sumilex 1000 x provided effective control of the disease.
