稻粒黑粉病是杂交水稻繁殖制种田的重要病害之一,它不仅降低繁殖制种的产量,而且严重影响不育系和杂交稻种的外观色泽和内在质量,防治稻粒黑粉病已成为当前杂交水稻繁殖制种的关键工作之一。为了探讨不同药剂对稻粒黑粉病的防治效果,我们进行了比较试验。 1 参试药剂 A、新灭灵:常州市青龙镇生产 B、克黑净:浙江农业大学 C、农试2号:南京农业大学 D、灭黑1号:江苏省沿海地区农科所 E、灭黑灵:江苏省农科院植保所
Rice powdery mildew is one of the most important diseases of hybrid rice breeding. It not only reduces the yield of breeding seed, but also seriously affects the appearance color and internal quality of CMS and hybrid rice, It becomes one of the key tasks of hybrid rice seed production. In order to explore the different agents on rice grain powdery mildew control effect, we conducted a comparative test. 1 test agent A, the new off the spirit: Changzhou Qinglong Town Production B, grams black net: Zhejiang Agricultural University C, Agricultural Tests 2: Nanjing Agricultural University D, off the black 1: Jiangsu Provincial Coastal Institute of Agricultural E, Off the Black Spirit: Plant Protection Institute of Jiangsu Academy of Agricultural Sciences
