In our cuntry, rice agriculture is commonly applied in center of Edirne, Uzunköprü, Meriç, İpsala, Keşan and Enez regions which meet 25% of sowing area and % 28 of rice production in our country. The weeds which causes some problems are Echinochloa crus-galli, E. oryzoides, Cyperus difformis, Diplachne fus ca, Polygonum lapatifolium, Paspalum paspaloides, Lindernia dubia and Ammania coccinea., Diplachne fus ca has entered to our country in recent years grass and began to spread very quickly. In 2008, this study was carried out because of the difficulty of conflict with  D. fus ca and to compete with rice. Experiments were made in two different phenologic development period of  D. fus ca in Uzunköprü. Assay was established as 4-character and four iteration by Randomized Complate Blocks type design. Before grass  tillering period of D. fus ca ; the effectiveness of cyhalafop – buthyl with 75 ml/da dose was 79% at day 18 and 82% at day 33, and 100% at day 18 and 33 with 150 ml/da dose. The effectiveness of fenoxaprop-p-ethyl + izoxafen effective herbicide at 80 ml/da dose was determined as 95%  and 98%  at day 18 and 33,  respectively.  In tillering period of Diplachne fus ca; when cyhalafop - buthyl was applied at 100 ml/da dose, it was found to be effective as 71%  at day 26, 73% at day 45 and at 150 ml/da dose, 100% at day 26 and 45 days and for Fenoxaprop-p-ethyl + izoxafen at 100 ml/da dose, it was found as 97% at day 26 and 98% at day 45
