    Study on the Herbicide Activities of N-Nitro-Diphenyl Urea Derivatives

      摘要
    • 摘要: 测定了6个N-硝基二苯基脲衍生物( Ⅰ )在500 mg/L浓度下对稗草Echinochloa crusgalli和绿苋Amaranthus viridis的除草活性,从中筛选出两个化合物 Ⅰ b 、 Ⅰ e 做系列浓度试验。结果表明,它们对稗草、绿苋均表现出一定的抑制活性,且随着浓度增加,抑制活性增强。

       

      Abstract: The herbicide activities of six N-nitro-diphenyl urea derivatives ( Ⅰ ) with concentration of 500 mg/L on Echinochloa crusgalli and Amaranthus viridis were tested. Ⅰ b and Ⅰ e were selected for herbicide activity test under concentrations of 125、250、500、750、1 000 mg/L on Echinochloa crusgalli and Amaranthus viridis. The results showed that Ⅰ b and Ⅰ e had restraining activities on Echinochloa crusgalli and Amaranthus viridis. The restraining activities were enhanced when their concentrations were increased.
