Negative Cross-Resistance of Acetolactate Synthase Inhibitor–Resistant Kochia (Kochia scoparia) to Protoporphyrinogen Oxidase– and Hydroxyphenylpyruvate Dioxygenase–Inhibiting Herbicides

  • Hugh J. Beckie (a1), Eric N. Johnson (a2) and Anne Légère (a1)


This greenhouse experiment examined the response of homozygous susceptible and acetolactate synthase (ALS) inhibitor–resistant plants from six Canadian kochia accessions with the Pro197 or Trp574 mutation to six alternative herbicides of different sites of action. The null hypothesis was ALS-inhibitor–resistant and –susceptible plants from within and across accessions would respond similarly to herbicides of different sites of action. This hypothesis was accepted for all accessions except that of MBK2 with the Trp574 mutation. Resistant plants of that accession were 80, 60, and 50% more sensitive than susceptible plants to pyrasulfotole, mesotrione (hydroxyphenylpyruvate dioxygenase [HPPD] inhibitors), and carfentrazone (protoporphyrinogen oxidase [PPO] inhibitor), respectively. However, no differential dose response between resistant and susceptible plants of this kochia accession to bromoxynil, fluroxypyr, or glyphosate was observed. A previous study had found marked differences in growth and development between resistant and susceptible plants of this accession, but not of the other accessions examined in this experiment. Negative cross-resistance exhibited by resistant plants of accession MBK2 to PPO and HPPD inhibitors in this experiment may be a pleiotropic effect related to the Trp574 mutation.

Este experimento de invernadero examinó la respuesta a seis herbicidas alternativos con diferentes sitios de acción de plantas de seis accesiones canadienses de Kochia scoparia, homocigotas susceptibles y resistentes a herbicidas inhibidores de acetolactate synthase (ALS) con las mutaciones Pro197 o Trp574. La hipótesis nula fue que plantas resistentes y susceptibles a inhibidores de ALS dentro y entre accesiones responderían en forma similar a herbicidas con diferentes sitios de acción. Esta hipótesis fue aceptada para todas las accesiones excepto MBK2 con la mutación Trp574. Comparadas con las plantas susceptibles, las plantas resistentes de esta accesión fueron 80, 60 y 50% más sensibles a pyrasulfotole, mesotrione (inhibidores de hydroxyphenylpyruvate dioxygenase [HPPD]) y carfentrazone (inhibidor de protoporphyrinogen oxidase [PPO]), respectivamente. Sin embargo, no se observó una respuesta a dosis diferenciada entre plantas resistentes y susceptibles de esta accesión de K. scoparia al ser tratadas con bromoxynil, fluroxypyr o glyphosate. Un estudio previo había encontrado diferencias marcadas en crecimiento y desarrollo entre plantas resistentes y susceptibles de esta accesión, pero no en las otras accesiones examinadas en este experimento. La resistencia cruzada-negativa que mostraron las plantas resistentes de la accesión MBK2 a inhibidores PPO y HPPD en este experimento podría ser un efecto pleiotrópico relacionado a la mutación Trp574.
