介绍了一种新的方法合成异噁草醚,其结构经核磁共振谱和质谱等确证。初步生测结果表明,异噁草醚在45g/hm2有效成分用量下对稗草的防效达100%,对水稻具有较好的安全性(抑制率25%)。
A new method for the synthesis of clomazone was introduced. Its structure was confirmed by NMR and MS. The results of preliminary bioassay showed that the control effect of clomazone on barnyardgrass was 100% under the dosage of 45g / hm2, which had good safety to rice (the inhibition rate was 25%).
