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。
The results showed that B (11) treatment had the best control effect, the relative seedling protection effect was 96.7%, the relative aphid-resistant effect was 87.5% Significantly better than the existing field production control, and can significantly promote cotton seedling growth and development. Because there was no significant difference in the control efficacy between the two drug combinations of B (11), it is recommended that the dosage of B (11) (0.6%) be used in the promotion of production.
