- 摘要:
- 为了明确11%砜嘧磺隆·高效氟吡甲禾灵可分散油悬浮剂对马铃薯的安全性及对一年生禾本科及阔叶杂草的防除效果，于2016年进行了田间药效试验。结果表明：11%砜嘧磺隆·高效氟吡甲禾灵可分散油悬浮剂在马铃薯苗后，一年生杂草2～4叶期茎叶均匀喷雾，在试验剂量范围内（制剂量360～1 080 mL·hm-2）安全性很好，施药后30 d，总株防效为63.6%～91.8%，总鲜重防效为70.1%～96.2%，适宜施用量为制剂量540～720 mL·hm-2（有效成分用量59.4～79.2 g·hm-2）。
- Abstract:
- In order to confirm the safety to potato and control efficacy to annual grass and broadleaf weeds on 11% rimsulfuron-haloxyfop-p-methl OD,field efficacy test was conducted in 2016.The results showed that after the potato seedling,11% rimsulfuron-haloxyfop-p-methl OD was sprayed leaf evenly during 3 to 5 leaf stage of annual weeds,security performance was very good in the dose range of test(dosage was 360～1 080 mL·hm-2); after spraying for 30 d,the total plant control effect was 63.6%～91.8%,the total fresh weight control effect was 70.1%～96.2%,the suitable dosage was 540～720 mL·hm-2(active ingredients dosage was 59.4～79.2 g·hm-2).
