在日本全国各地施用除草剂杀草丹的水田中,发生了一种奇怪的水稻生长障碍——矮化症。虽然早在1976年以前,就有一部分农民和研究人员观察到这种意外现象,但到1977年富山县、千叶县,大分县等地广泛发生时,才开始查找原因并寻求有效的对策。尽管目前已经采取了某些相应的措施,矮化症却仍在各地继续发生。 A strange rice growth disorder, dwarfism, has taken place in paddy fields where herbicide herbicide Dan Dan is used throughout Japan. Although some peasants and researchers observed such surprises as early as 1976, they began to find the cause and seek effective countermeasures by 1977 when widespread occurrence occurred in places such as Toyama, Chiba and Oita. Although some corresponding measures have been taken so far, dwarfism still continues to take place in various places.
