| Abstract: | It was effective to control cereal weeds with 10.5% haloxyfop-R-methyl, 5% NC-302D(+),15% fluazifop-p-butyl or 5% quizalofop-p-ethyl and coco-grass and broad-leaf weed with 25% bentazone after seeds germinated. When dealt before sowing, 48% trifluralin could be used to control both cereal weeds and broad-leaf weeds and the controlling efficiency was 90% respectively and 70%. The results also showed that 60% butachlor, 50% acetochlor and 56% MCPA-Na were dangerous to three-coloured amaranth. |
