| 中文摘要: |
| 采用茎叶喷雾法测定了20%辛酸EC 3.6、10.8、32.4、48.6、64.8和97.2 kg/hm 2(有效成分,下同)对非耕地杂草的防除效果。结果表明,20%辛酸EC 64.8～97.2 kg/hm 2处理药后7 d对总草株防效为86.98%～95.65%,药后15 d鲜重防效为85.40%～94.86%,显著高于对照药剂41.7%草甘膦AS 1.0 kg/hm 2处理,与对照药剂20%百草枯AS 0.6 kg/hm 2处理相近;20%辛酸EC 3.6～32.4 kg/hm 2处理药后7 d对总草株防效及药后15 d鲜重防效均低于或显著低于对照药剂41.7%草甘膦AS 1.0 kg/hm 2处理和20%百草枯AS 0.6 kg/hm 2处理。20%辛酸EC可有效地控制非耕地杂草,推荐使用剂量为64.8～97.2 kg/hm 2。 |
| 英文摘要: |
| The efficacies of octanoic acid 20% EC at the active ingredient contents of 3.6,10.8,32.4,48.6,64.8 and 97.2 kg/hm 2 were tested against weeds in non cultivated fields by using the foliage spray method. The results showed that the efficacies of octanoic acid 20% EC at the active ingredient contents of 64.8-97.2 kg/hm 2 on total weeds were 86.98%-95.65% against the total weeds 7 days after spray, and the efficacies on fresh weight were 85.40%-94.86% 15 days after spray, which were significantly higher than that of glyphosate 41.7% AS at 1.0 kg/hm 2, but similar to that of paraquat 20% AS at 0.6 kg/hm 2. The efficacy of octanoic acid 20% EC at the active ingredient contents of 3.6-32.4 kg/hm 2 against total weeds 7 days after spray and its efficacy on fresh weight 15 days after spray were lower or significantly lower than that of glyphosate 41.7% AS at 1.0 kg/hm 2 and paraquat 20% AS at 0.6 kg/hm 2. Octanoic acid 20% EC could effectively control weeds in non cultivated fields, and its recommended dosage is 64.8-97.2 kg/hm 2. |
