There are three kinds of so-called "hotarui" Scirpus juncoides Roxb var, hotarui Ohwi, S. juncoides Roxb. var. ohwianus T. Koyama and S. wallichii Nees in Japanese paddy rice fields of which seedlings are so like one another that they are hardly distinguishable. The present authors studied the effects of granular formulations of CG102 [4.4% (w/w) piperophos + 1.1% (w/w) dimethametryn], TH63 [4.4% (w/w) piperophos + 1,1% (w/w) dimethametryn + 10.0% (w/w) bentazon], piperophos [4.4% (w/w)], dimethametryn [1.1% (w/w)] and bentazon [10.0% (w/w)] on these three kinds of Scirpus to establish a control method which gave the desirable effect. 1. CG 102 and TH 63 showed excellent effects on S, juncoides var. hotarui even under heavy water leakage condition. The herbicides also showed high effects on S. juncoides var. ohwianus and S. wallichii, but these effects were reduced under water leakage condition. The reduction of the effects of TH 63 on S. juncoides var. ohwianus and S. wallichii under remarkable. water leakage condition was prevented by keeping the water depth shallow, 1cm at the treatment of TH63. S juncoldes var hotarui was susceptible to all the three active ingredients, especially di-methametryn, but the other species were susbeptible to only piperophos. The effects of simultaneous applications of piperophos and dimethametryn or piperophos, dimethametryn and bentazon were higher than those of single application of eacsh active ingredient.
