The efficacy of bispyribac sodium, fenoxaprop-p-ethyl + ethoxysulfuron, and propanil+butachlor were evaluated in greenhouse and field experiments, Weed Science, Crop and Environmental Sciences Division, IRRI in February - April 2013. The field plots had high weed density that had 4-6 leaves when the herbicides were applied at 15 days after land preparation. In the greenhouse experiment we grew Echinocloa crus-galli, Ludwigia octovalvis, Cyperus iria, weedy rice (Oryza sativa f. spontanea Acc. 105798 (THA)), and rice cultivars KDML105 and IR64 in pots. At 7 days after rice and weed germination, we sprayed herbicides to the above-mentioned species using a research track sprayer. The results showed that bispyribac sodium and fenoxaprop-p-ethyl+ethoxysulfuron... |

Weeds play an important role in decreasing yield in dry-direct seeded rice. However, using herbicide could effectively control weed and help increase rice yield. The objective of this research was to investigate the effect of herbicide application on weed control and rice yield in dry-direct seeded paddy field. The experiment was conducted at a farmer’s field, Khon Kaen province, from June to November of 2012 with the use of rice variety KDML 105. The nine treatments were 1) no weeding, 2) hand weeding, 3) oxadiazon, 4) oxadiargyl, 5) oxyfluorfen, 6) pendimethalin, 7) butachor/propanil, 8) clomazone and 9) bispyribac-sodium. The rates of herbicide application of treatments 3-9 were 120.0, 40.0, 28.2, 198.0, 175.0, 38.4 and 4.0 g ai/rai, respectively, The... |
