15％吡氟酰草胺OD与不同药剂复配对水稻移栽田杂草防效及安全性OA
Efficacy and Safety of 15％Diflufenican OD Combined with Different Adjuvants for Weed Control in Transplanted Rice Fields
15％吡氟酰草胺OD与不同药剂复配(在水稻移栽前1 d施药)对多种杂草的防效及对水稻的安全性田间试验,为水稻移栽田杂草防除提供理论依据和数据支撑.结果表明,药后20 d 15％吡氟酰草胺OD 80 mL/667 m2+35％丙炔草酮·丁草胺EW 100 mL/667 m2和 15％吡氟酰草胺 OD 80 mL/667 m2+40％丙草胺 EC 80 mL/667 m2 对杂草防效较高,分别为 98.08％、97.12％.药后 40 d 15％吡氟酰草胺 OD 80 mL/667 m2+35％丙炔恶草酮·丁草胺 EW 100 mL/667 m2 对杂草防效最高,为 84.46％.15％吡氟酰草胺 OD 80 mL/667 m2 和 160 mL/667 m2 用量单剂和复配剂处理的水稻在药后 10 d 有药害症状,药后 20 d 调查水稻恢复正常,各处理在水稻移栽前施药对水稻安全,具有应用前景.
A field experiment was conducted to determine the rice safety and control efficacy against various weeds of 15％diflufenican OD combined with different herbicides applied one day before rice transplanting,providing theoretical basis and data support for weed control in transplanted rice fields.The results showed that at 20 days after application,the combinations of 15％diflufenican OD 80 mL/667 m2+35％oxadiargyl·butachlor EW 100 mL/667 m2 and 15％diflufenican OD 80 mL/667 m2+40％pretilachlor EC 80 mL/667 m2 exhibited high weed control efficacy,reaching 98.08％and 97.12％,respectively.At 40 days after application,the combination of 15％diflufenican OD 80 mL/667 m2+35％oxadiargyl·butachlor EW 100 mL/667 m2 achieved the highest weed control efficacy of 84.46％.Rice treated with 15％diflufenican OD alone(80 mL/667 m2 and 160 mL/667 m2)and its combinations showed phytotoxicity symptoms at 10 days after application,but recovered to normal by 20 days after application.All treatments applied before rice transplanting were safe for rice and had good application prospects.
