Experiments were carried out to evaluate the effect of chemical control on Scirpus planiculmis FR. SCHM. The results obtained are as follows ; 1 . Bentazon which was applied as foliar treatment in S. planiculmis, was a highly effective herbicide and did not cause injury to rice plant (Tables 3 and 4). 2 . Foliar treatment with bentazon was ineffective in primary shoots less than 10cm in height (Figure 2). The optimum application time of bentazon was 30-40 days after transplanting of rice plant and repeated application of bentazon was recommended in the case of high planting density. 3 . The parent tuber could not sprout as it withered by foliar treatment with bentazon (Table 9). 4 . Bensulfuron methyl was most effective without causing injury to rice plant in the case of soil-application (Tables 1 and 2).
