玉米丝黑穗病（Sphacelotheca reiliana）主要为害玉米的雄穗（天花）和雌穗（果穗）,一旦发病,通常全株没有产量。随着玉米种植面积逐年扩大,玉米丝黑穗病已呈发生蔓延的趋势。为筛选防治玉米丝黑穗病的有效药剂,我们用新疆振农种衣剂有限公司生产的20％克·福悬浮种衣剂,在伊宁县进行了田间药效试验,现将结果整理如下: 一、材料及方法 1、供试品种:伊单9号 2、试验方法 先将玉米种子按20％克·福悬浮种衣剂与玉米种子重量比1:35、1:40、1:45的比例进行包衣处理,对照采用50％福美双可湿性粉剂,按种子重量5‰用药量对种子进行拌种处理。试验设两种药剂四个剂量处理和一个不拌种的对照,各处理重复四次。
Corn head smut (Sphacelotheca reiliana) is mainly affected tassel (smallpox) and ear (ear) corn, once the disease, usually the whole plant no yield. With the corn planting area expanding year by year, maize smut has been showing the trend of spread. In order to screen the effective agent for preventing and treating maize head smut, we used the 20% g.Fu suspension suspended seed coating produced by Xinjiang Zhennong Seed Coating Co., Ltd. to carry out the field efficacy test in Yining County. The results are as follows: First, the material and methods 1, the test varieties: Yidan 9 2, the test method first maize seeds according to 20% g Fuxu suspended seed coating agent and corn seed weight ratio of 1:35, 1:40, 1:45 The proportion of coating treatment, the control using 50% thiram wettable powder, according to the seed weight of 5 ‰ dosage seed dressing treatment. The experiment set two doses of four doses of treatment and a control not mixed seed, each treatment repeated four times.
