Application techniques of bispyribac-sodium for controlling weeds were studied in direct seeded rice fields in Zhejiang, China in 1998 - 1999. Results showed bispyribac-sodium is very effective on gramineae, sedge and broad-leaf weeds including Echinochloa crusgalli , Paspalum distichum, and Alternanthera philoxeroides , but not on Leptochloa chinensis. It was recommended that 10% bispyribac-sodium SC be sprayed at 225- 450 ml/ hm2 with 450 L/hm2 of water during 3 to 5 leaf stage of barnyardgrass, and sometimes applied with thiobencarb or fenoxaprop-p-ethyl specially for L. chinensis.
