摘要
田间小区试验结果表明 ,在春大豆苗 2片复叶期 ,禾本科杂草 3 -5叶期 ,阔叶杂草株高 5 -7cm时施药 ,6.5 %乐田特乳油对大豆田的稗草、藜、本氏蓼、反枝苋、龙葵、香薷、卷茎蓼等一年生禾本科杂草和阔叶杂草有良好防效。虽然对大豆叶片可造成接触性药害斑 ,但在 1周后即可恢复正常 ,不影响大豆后期生长发育和开花结实 ,对大豆安全。适宜用药量为 6.5 %乐田特乳油 1 65 0 -1 80 0ml/hm2 。
The field trial results showed that Radiant-S could effectively control the grasses and broadleaf weeds in spring soybean field. The optium application timing was at 2nd trifoliate-leaf stage of soybean, 3-5 leaves of grass weeds and 3-7 cm high of broadleaf weeds. The suitable dosage was Radiant-S 1650-1800ml/hm 2. These dosages were safe to spring soybean.
