It is native to east Asia, although it is endangered in Japan due to excessive use of acetolactate synthase-inhibiting herbicides.[2][3] In China, it has become a significant threat to rice production, particularly in Liaoning province, where it has evolved high levels of resistance to the herbicide bensulfuron-methyl.[4]
