- 摘要:
- 田间试验结果表明, 在小麦分蘖盛期及阔叶杂草基本出齐时施药, 伴地农对春小麦田的卷茎蓼、藜、鼬瓣花、香薷、本氏蓼、反枝苋等1 年生阔叶杂草和蒿、苣荬菜等多年生杂草有良好的防效, 防效高于2 , 4 -D 丁酯, 而对问荆和鸭跖草的防效差。伴地农与2 , 4 -D 丁酯混用可降低伴地农的用药量, 对上述杂草的防效高于2 , 4 -D 丁酯单用。适宜用药量为22 .5 %, 伴地农乳油单用1 5001 800 mL/hm2 , 与72 % 2 , 4 -D 丁酯乳油混用为1 125 +375 mL/hm2 , 在此剂量范围内对小麦安全。
- Abstract:
- This t rial result showed that Pardner could ef fectively control the broad-leaved w eeds in spring w heat field , sprayed at the period of w heat tiller and weed germination .But the cont rol ef fect is very low to Bot tlebrush and Common dayf lower .The effect of mix ture of Pardner and 2 , 4 -D butytate is hig her than that of using only 2 , 4 -D buty tate .The suitable dosage is Pardner 1 5001 800mL/ hm2 or the mixture of Pardner and 2 , 4 -D buty tate 1 125 +375mL/hm2 .These dosages are safe to spring w heat .
