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... |

Experiment on pre-emergence and post-emergence herbicide application for weed control in farmer's field conducted in Ban Yangrak, Khokcharoen district, Lopburi province, during August-November 2008. The experiment laid out in RCB, composed of 10 treatments, with 3 replications. The objective of this experiment was to study on the efficiency of herbicides and their effect on field corn, KSX 4901 variety. The results revealed that weed found in the experiment were purple nutsedge (Cyperus rotundus), wild poinsettia (Euphorbia heterophylla), horse purslane (Portulaca oleracea), tropical spiderwort (Commelina benghalensis), running grass (Brachiaria reptans), and jungle rice (Echinichloa colona). The application of 2,4-D, glufosinate, fluroxypyr and paraquat... |
