Effect of weed control treatments on transplanted rice (Oryza sativa L.)

Abstract: Two field experiments were conducted at El-Serw, Agricultural Research Station, during 1999 and 2000 summer seasons to study the effect of some promising herbicides i.e. Fentracamide at 150 g/ fed., Fluthiamide at 100 g/fed. and Oxadiargyl at 90 g/fed as compared with the recommended herbicides Benthiocarb at 2 L / fed., and Butachlor at 1.5 L /fed. on weeds and transplanted rice(Oryza sativa L.). The results showed that the predominant grassy weeds were Echinochloa crus-galli (L.) P.Beauv. and Echinochloa colonum (L.) Link and the sedge Cyperus difformis L. in the two seasons. Fentracamide, Fluthiamide and Oxadiargyl caused significant reduction in the percentage of grassy weeds by 98.1-100, 94.2-95.6 and 96.2-100 %, respectively and sedge weed by 99.5-100, 98.4-100 and 99.3-100 %, respectively and reflected an increase in rice grain yield. Yield in the three treatments ranged from 2.142-2.293, 2.268-2.495 and 2.31-2.56 t/fed., respectively in both seasons. Meanwhile, Benthiocarb, Butachlor and hand weeding twice gave significant reduction in the percentage of grassy weeds by 95.8-100, 53.6-61.5 and 77.7-79.4 %, respectively and sedge weed by 99.5-99.6, 98.2-100 and 97.3-98.5 %, respectively and gave significant increase in rice grain yield. Yield with the respective previous treatments ranged from 3.109-3.293, 2.436-2.68 and 2.688-2.856 t/fed., respectively in both seasons. These herbicides were equal in controlling weeds and increase rice productivity. The three promising herbicides (Fentracamide, Fluthiamide and Oxadiargyl) can replace the recommended herbicides (Benthiocarb and Butachlor).
