金豆是一种新的选择性广谱除草剂。我们为了评价金豆单用25、30、40、45、50、75、100、150gai/ha,与普施特混用25+25、50+50gai/ha剂量下防除杂草效果,1992-1997年在哈尔滨黑土上进行试验。结果表明,金豆对禾本草和阔叶草均有良好防除效果,苗后茎叶处理比苗前土壤处理药效更好。采用硫酸铵作助剂可以改善药效。适宜的施药期为大豆真叶到1片复叶期。适宜剂量为金豆单用40-50gai/ha,与普施特混用25+25gai/ha。大豆对金豆耐药性好。如果使用两倍的推荐剂量(≥100gai/ha),又遇到特殊潮湿条件,可发生短暂的药害,但能恢复。
Golden beans is a new selective broad-spectrum herbicide. In order to evaluate the effects of weeds on the weeds in 25, 25, 40, 40, 50, 75, 100, 150 gai / ha and 25 + 25 and 50 + 50 gai / ha, respectively, test. The results showed that the golden beans had good control effect on both gramineous grass and broad-leaved grass, and the effect of post-emergence stem-leaf treatment was better than the pre-emergence soil treatment. Ammonium sulfate as adjuvant can improve efficacy. Appropriate application period for soybean leaves to a complex leaf period. The appropriate dose of gold beans alone with 40-50gai / ha, and pinaster mixed with 25 + 25gai / ha. Soybean good resistance to gold beans. If twice the recommended dose (≥100gai / ha) is used, and if it encounters special wet conditions, a short phytotoxicity may occur but recovery will occur.
