苄草唑

苄草唑用途

本品属吡唑类除革剂，是叶绿素合成抑制剂。为广谱稻田除草剂，水稻移栽后1～7d杂草萌芽前或杂草萌芽后施用3kg(a.i.)/ha．可防除一年生和多年生杂草。用于旱田除草效果不好。可用于直播稻田，但是温度高于35℃，会发生暂时性作物药害．不得在稗草长到4～5叶期后施药，而本品的杀草谱随处理时间而异，在灌溉条件下，处理后3～5周，对稗草和慈菇属有着持久的抑制作用，其活性取决千处理时的温度，当低于15℃，活性下降，尤其对萤蔺，低温下防效更差。

苄草唑制备

1，3-二甲基－5-吡唑啉酮与碳酸钾在二氧六环中回流1h，然后与2，4-二氯苯甲酰氯回流反应2h，生成物再与α-溴代苯乙酮回流反应40min，得到92%苄草唑，或者上述生成物与乙腈、α-氯代苯乙酮、碳酸钾和碘化钾回流反应1h，也可制得苄草唑。
