以稻茬直播小麦田杂草防除为目标,验证50 g/L唑啉.炔草酸(大能)对麦田禾本科杂草的防效及对小麦安全性。结果麦明,唑啉·炔草酸杀草谱广,对小麦田禾本科杂草防效高,特别是对顽固性杂草硬草有很好的防除效果。冬前杂草3~4叶期,50 g/L唑啉.炔草酸EC 900 mL/hm2、兑水30 kg/hm2;春季3月中旬,杂草5~7叶期,用50 g/L唑啉·炔草酸1 200 mL/hm2、兑水525 kg/hm2均匀喷雾,对硬草株防效均可高达100%。且对小麦安全,增产显著。
The control effect of 50 g / L oxazoline and clodinafop-p-ethylbenzoate on weeds in wheat field and its safety to wheat were investigated with weed control in direct seeding wheat fields. The results of wheat, oxazoline, acetylcalytic acid broad spectrum to kill grass, grass wheat weeds in wheat field control effect is high, especially hardy stubborn grass have good control effect. Winter weed 3 to 4 leaf stage, 50 g / L of oxazoline. Acetylene acid EC 900 mL / hm2, watered 30 kg / hm2; spring mid-March, weeds 5-7 leaf stage, with 50 g / L Azoline, acetylene oxalic acid 1 200 mL / hm2, watered 525 kg / hm2 uniform spray, hard grass strains can be as high as 100%. And the safety of wheat, a significant increase.
