| 中文摘要: |
| 为了筛选能有效防除西藏青稞田中曼陀罗Datura stramonium的防除药剂, 本研究通过田间试验测定10%唑草酮可湿性粉剂、560 g/L灭草松水剂、80%唑嘧磺草胺水分散粒剂和10%氟唑磺隆可分散油悬浮剂 4种除草剂对曼陀罗的株防效、鲜重防效。结果显示, 曼陀罗对10%唑草酮可湿性粉剂和560 g/L灭草松水剂表现出较高敏感性。药后21 d, 10%唑草酮可湿性粉剂对曼陀罗的株防效可达92.59%, 560 g/L灭草松水剂对曼陀罗的株防效在85.56%~89.26%之间; 两者对曼陀罗的鲜重防效均高于94.44%。综合考虑株防效和鲜重防效, 西藏青稞田中可选用10%唑草酮可湿性粉剂20 g/667m2和560 g/L灭草松水剂100 mL/667m2。 |
| 英文摘要: |
| To identify effective herbicides for controlling Datura stramonium in highland barley fields in Xizang, a field experiment was conducted to evaluate the plant control efficacy and fresh weight reduction efficacy of four herbicides: carfentrazone-ethyl 10% WP, bentazone 560 g/L AS, flumetsulam 80% WG, and flucarbazone-sodium 10% OD. The results showed that D.stramonium was highly susceptible to carfentrazone-ethyl 10% WP and bentazone 560 g/L AS. On the 21th day after application, carfentrazone-ethyl 10% WP achieved a plant control efficacy of 92.59%, while that of bentazone 560 g/L AS ranged from 85.56% to 89.26%. Both herbicides demonstrated fresh weight reduction efficacies exceeding 94.44%. Considering both metrics, the recommended dosages for highland barley fields were 20 g/667m2 for carfentrazone-ethyl 10% WP and 100 mL/667m2 for bentazone 560 g/L AS. |
