一、青稞条纹病防治试验供试品种为帕里白青稞。试验方法:小区试验采用随机排列,重复三次。每种药剂以2～3个药量作为拌种处理,种子处理后一周播种,成熟前按有效穗调查发病率,以此计算相对防治效果。试验结果: 从表一可看出麦穗宁和氯硝散乳剂的防治效果都很好,使用拌种浓度在0.1％时,相对防治效果都在90％以上。氟硅酸的防治效果不理想。这些药剂对青稞苗均有轻微药害,用药量均不可超高0.3％,否则会降低出苗率。
A, barley stripe disease prevention and control test varieties for the Pari White Qingliu. Test Methods: Cell test using random arrangement, repeated three times. Each agent to 2 to 3 doses as seed dressing treatment, seeding week after sowing, according to the effective spike incidence before maturity, in order to calculate the relative control effect. Test results: It can be seen from Table 1 that wheat Nose and Chlorhexidine powder have good control effects. When the seed dressing concentration is 0.1%, the relative control effects are all above 90%. Fluorosilicic acid control effect is not satisfactory. These agents have a slight injury to barley seedlings, the dosage should not exceed 0.3%, otherwise it will reduce the emergence rate.
