Study on the Effect of Two Kinds of Penoxulam Herbicides on Wheat Seed Biologic Activity
【摘要】 以小麦为试材,测定了氯嘧磺隆和苯磺隆对小麦种根的抑制作用。结果表明,氯嘧磺隆48和72 h对小麦种根的EC50分别为45.65和10.99 mg/kg;苯磺隆48和72 h对小麦种根的EC50分别为1 489.65和537.44 mg/kg。
【Abstract】 We measured the restraining activity of chlorimuronethyl and tribenuron-methyl in wheat seed root.The result showed that the EC50 was（45.65）?mg/kg and 10.99?mg/kg of chlorimuron-ethyl in wheat seed root in 48?h and 72?h.The result also showed that the EC50 was 1?489.65?mg/kg and（537.44）?mg/kg of Tribenuron-methyl in wheat seed root in 48?h and 72?h.
