日本除草剂登记与使用情况概述

The Review on Herbicide Registration and Application in Japan

本文综述日本在除草剂登记方面的法律依据、基本登记情况、登记资料要求、除草剂使用情况和存在问题等,重点介绍生测资料、残留资料方面的登记要求。日本农作物以水稻为主,整个耕地的70%都用来种植水稻,在水稻上登记的除草剂的要求最高,除了其他旱田登记的资料要求的冲绳试验、作用特性试验、适应性1试验和适应性2试验之外,试验点的数量大幅度增加,所要求的包括13个点的砂壤土试验在内总的试验报告总数在41个以上。日本在除草剂登记管理及使用方面的风险控制经验值得借鉴。

The agricultural chemicals regulations in Japan, the situaton of herbicide registra- tion, the data requriements, the application and some problems of herbicide in Japan were reviewed. The bioassay and residue data for herbicide registraton were discussed in detail. The paddy rice was the most important crop in Japan, and was planted for 70% of the total arable land. It＇s not easy to get the registraion for the new herbicide. Besides the requirement of Chongshen trial, mechanism and action trial, the adaption phase 1 trial and adaption phase 2 trial, some additional trials were also required. There are 41 reports totally includi,g 13 reports which the soil type should be sandy soil. It＇s good to learn from the Japan to reduce the risk of herbicide in this field.
