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).
