Genetic diversity and spread of glyphosate-resistant flaxleaf fleabane [PDF]
Bulletin of the National Research Centre, 2020 Background Continual application of herbicides for flaxleaf fleabane control readily results in the evolution of herbicide resistance. Flaxleaf fleabane has evolved resistance to different modes of action herbicides in many countries.

Resistance of flaxleaf fleabane (Conyza bonariensis (L.) Cronquist) to glyphosate
Bulletin of the National Research Centre, 2020 Background Resistance to glyphosate has been reported in flaxleaf fleabane populations within a number of grain growing areas in southern Queensland and northern New South Wales and other cropping regions across Australia.

Management and development of fleabane plants in central Brazil [PDF]
Planta Daninha, 2020 Background: Fleabane plants (Conyza spp.) resistant to glyphosate herbicide are found infesting areas in the Central-West and Southeast regions of Brazil, but its management is not a concerning problem for summer crops in these regions as in the South ...

Glyphosate-resistant hairy fleabane documented in the Central Valley [PDF]
California Agriculture, 2008 In recent years, growers and pest consultants have reported poor control of the weed hairy fleabane in some areas of the Central Valley. Hairy fleabane seeds were collected from Esparto, Fresno and Reedley, Calif., and greenhouse-grown seedlings were ...

Paraquat Resistance of Sumatran Fleabane (Conyza sumatrensis) [PDF]
Planta Daninha, 2019 : In Brazil, some populations of Conyza bonariensis and C. canadensis are glyphosate resistant and there are populations of C. sumatrensis (Sumatran fleabane) presenting multiple resistance to both glyphosate and chlorimuron.

HAIRY FLEABANE AS A SOURCE OF MAJOR INSECT PESTS OF SOYBEAN [PDF]
Planta Daninha, 2016 Weeds compete with crops for essential inputs, but they are also important hosts for pests, both during the crop and between crops. Hairy fleabane (Conyza bonariensis) is an important weed growing in both summer and winter crops.

Control of glyphosate-resistant Canada fleabane in corn with preplant herbicides [PDF]
Canadian Journal of Plant Science, 2016 Nine preplant herbicides were tested for the control of glyphosate-resistant (GR) Canada fleabane in corn. At eight weeks after treatment (WAT), the herbicides that resulted in the greatest control and least amount of density and biomass of GR Canada fleabane were dicamba/atrazine (99%), mesotrione + atrazine (97%), saflufenacil/dimethenamid-p (97 ...

Synergism of the glyphosate and saflufenacil combination for controlling hairy fleabane
Pesquisa Agropecuária Tropical, 2015 In Brazil, hairy fleabane stands out among the main weeds of soybean crops, due to its aggressiveness and resistance to glyphosate. Thus, to avoid the selection of resistant populations to the glyphosate herbicide, the use of other herbicides has become ...
