Occurrence of sulfonylurea-resistant biotypes of Scirpus juncoides Roxb. var. ohwianus. T. Koyama in paddy fields of Hokkaido prefecture, Japan



Occurrence of sulfonylurea-resistant biotypes of Scirpus juncoides Roxb. var. ohwianus. T. Koyama in paddy fields of Hokkaido prefecture, Japan



Journal of Weed Science and Technology 44(3): 228-235



Scirpus juncoides var. ohwianus, a perennial sedge, was one of the most serious paddy weeds from 1960-80 in Japan. The weed had been easily controlled by sulfonylurea herbicides in the 1990s in Hokkaido Prefecture, Japan.
