Halauxifen-Methyl+Diclosulam: New Option to Control Conyza spp. Prior Soybean Sowing [PDF]
Planta Daninha, 2019 : Control of Conyza spp. prior to soybean sowing has faced difficulties because of the resistance cases in Brazil, hence new herbicides as halauxifen-methyl + diclosulam are important to manage this specie.

Paraquat Resistance in Conyza [PDF]
Plant Physiology, 1985 A biotype of Conyza bonariensis (L.) Cronq. (identical to Conyza linefolia in other publications) originating in Egypt is resistant to the herbicide 1,1'-dimethyl-4,4'-bipyridinium ion (paraquat). Penetration of the cuticle by [(14)C]paraquat was greater in the resistant biotype than the susceptible (wild) biotype; therefore, resistance was not due to ...
