摘要
棉花不同种衣剂及用药量对棉苗根病和棉蚜防治试验结果表明，以B(11)处理防效最佳，相对保苗效果达96．7％，相对防蚜效果87．5％，显著优于现有的大田生产对照，并可明显促进棉苗的生长发育。由于B(11)的两个药种比之间防效差异不明显，因此，建议在生产推广中采用B(11)（0．6％）的用药量。
During 1997, the experiment of root rots and Aphis gossoypii control at cotton seedling stagewith different cotton seed coating formulations and dosages was conducted in Yuncheng City, ShanxiProvince. The results indicated that the relative control efficiency of treatment B11 were 96. 7% for rootrots and 87. 5% for cotton aphid. This treatment was also able to promote growth and development ofcotton seedling. The efficiency of treatment B11 was the best in all of herments tested. Because there was not obvious difference between two dosages (0.6 and 0. 8 a. i% ) of treatment B11 in the effectiveness ofmet rots and cotton aphid control, the former dosage was recommended to use.
