The sensitivity of Echinochloa weed species to different herbicides frequently used in paddy fields
Abstract:Echinochloa weed species, a group of the world’s worst weeds, cause serious damage to the rice production in China. Echinochloa genus contains about 35 species and more than 10 subspecies all over the world. In China, Echinochloa spp. contains about 10 species and 5 subspecies. Different species of this genus hold different susceptibilities to herbicides. Based on doses of herbicides inhibiting 50% of target weed species (ED50), we tested the sensitivities of 6 Echinochloa weed species to different herbicides frequently applied in rice fields. As to the sensitivity of the oxadiazon, Echinochloa colonum (l.) Link. > Echinochloa caudata Roshev. > Echinochloa crusgalli var. Mitis > Echinochloa crusgalli (l.) p. = Echinochloa glabrescens Munro ex Hook f. > Echinochloa crusgalli (l.) Beauv.;For the sensitivity of anilofos, Echinochloa crusgalli var. Mitis > Echinochloa colonum (l.) Link. > Echinochloa caudata Roshev. > Echinochloa glabrescens Munro ex Hook f. > Echinochloa crusgalli (l.) Beauv. > Echinochloa crusgalli (l.) p.;For the sensitivity of mefenacet baldheaded tares = Echinochloa glabrescens Munro ex Hook f. > Echinochloa crusgalli (l.) Beauv. = Echinochloa crusgalli var. Mitis > Echinochloa caudata Roshev. = Echinochloa crusgalli (l.) p.;For pendimethalin, Echinochloa crusgalli var. Mitis > Echinochloa crusgalli (l.) Beauv. = Echinochloa glabrescens Munro ex Hook f. > Echinochloa caudata Roshev. > Echinochloa crusgalli (l.) p. > Echinochloa crusgalli (l.) Beauv..For the sensitivity of quinclorac, Echinochloa crusgalli (l.) p. = Echinochloa crusgalli (l.) Beauv. > Echinochloa caudata Roshev. = Echinochloa glabrescens Munro ex Hook f = Echinochloa crusgalli var. Mitis > Echinochloa colonum (l.) Link.;For bispyribac - sodium sensitivity, Echinochloa crusgalli (l.) Beauv. = Echinochloa crusgalli var. Mitis = Echinochloa caudata Roshev. > Echinochloa crusgalli (l.) p. > Echinochloa colonum (l.) Link. > Echinochloa glabrescens Munro ex Hook f.;For the sensitivity of metamifop, Echinochloa crusgalli (l.) Beauv. = Echinochloa glabrescens Munro ex Hook f = Echinochloa crusgalli var. Mitis = Echinochloa caudata Roshev. = Echinochloa crusgalli (l.) p. > Echinochloa colonum (l.) Link.;For fenoxaprop - p - the sensitivity of the baton rouge, Echinochloa colonum (l.) Link. = Echinochloa caudata Roshev. = Echinochloa crusgalli var. Mitis = Echinochloa crusgalli (l.) p. = Echinochloa crusgalli (l.) Beauv. = Echinochloa glabrescens Munro ex Hook f..
