“…Higher‐plant ACCase catalyses the ATP‐dependent carboxylation of acetyl‐CoA to form malonyl, the precursor to fatty acids 1. Although most graminaceous weed species are susceptible to ACCase‐inhibiting herbicides, the development of resistance to these herbicides in most instances investigated has been attributed to an alteration of the target site 4, 13–17. Most studies have implicated insensitive ACCase as the mechanism conferring resistance to fenoxaprop‐P‐ethyl.…”

“…Since 1995 there have been increasing reports of concern about resistance to AOPP and CHD herbicides. It has been stated that, in most cases where grass‐weeds have evolved resistance to ACCase‐inhibiting herbicides, the commonest mechanism of resistance is enhanced metabolic detoxification18–20 and an insensitive ACCase 13–17, 22, 23. Furthermore, there have also been reported results of studies to determine the genetic and molecular basis of resistance conferred by an insensitive ACCase 23.…”

From paddy field observations in 2002 and 2004, fenoxaprop-P-ethyl resistance in Chinese sprangletop (Leptochloa chinensis (L.) Nees) has been studied using information collected from 11 sites in the Saphan-Sung district of Bangkok, Thailand. The resistant Chinese sprangletop was found in nine rice fields, whereas the susceptible Chinese sprangletop was found in only two rice fields. In greenhouse experiments, both fenoxaprop-P-ethyl-resistant and susceptible Chinese sprangletop from the same location were investigated for 50% growth reduction based on phytotoxicity, plant height and fresh and dry weight. The resistant Chinese sprangletop showed apparent resistance at 14-21 days after herbicide application at a rate of 21.1-337.6 g AI ha(-1). The resistance index of resistant Chinese sprangletop was 10-25 times higher than that of the susceptible Chinese sprangletop. In addition, Chinese sprangletop did not exhibit multiple resistance to oxadiazon, propanil and quinclorac. According to acetyl-CoA carboxylase (ACCase) assays, the level of ACCase specific activity in the resistant Chinese sprangletop was significantly higher than that in the susceptible Chinese sprangletop. Similarly, the ACCase activity of the resistant Chinese sprangletop was 10 times less sensitive to fenoxaprop-P-ethyl than that of the susceptible Chinese sprangletop, based on the I50 values. The present study of the mechanism responsible for resistance in the biotypes investigated indicated that there was a close association between the concentration-response at the whole-plant level and ACCase sensitivity to fenoxaprop-P-ethyl, and resistance to fenoxaprop-P-ethyl was conferred by a modified ACCase at the target site, as suggested by higher specific activity and less sensitivity to the herbicide.

“…Os primeiros casos de resistência para esta espécie vegetal foram documentados para os herbicidas inibidores de mitose (inibidores da polimerização de tubulina), e o mecanismo de resistência se deve ao local de ação do herbicida alterado (Mudge et al, 1984;Leach et al, 1995).…”

RESUMO -Dentre as causas da ineficácia no controle de plantas daninhas destaca-se a resistência delas aos herbicidas. Os objetivos deste trabalho foram avaliar a suspeita de resistência de Eleusine indica a inibidores de acetil-CoA carboxilase (ACCase) e investigar a ocorrência de resistência cruzada entre os inibidores de ACCase. Biótipo de Eleusine indica originado do Mato Grosso com suspeita de resistência aos herbicidas inibidores de ACCase foi avaliado em casa de vegetação na sua suscetibilidade para diversos produtos do grupo dos ariloxifenoxipropionatos e cicloexanodionas. Estudos de resposta à dose confirmaram que o biótipo era 18 vezes mais insensível ao sethoxydim do que biótipo suscetível nunca aspergido com herbicidas. Também se constatou resistência cruzada ao fenoxaprop, cyhalofop, propaquizafop e butroxydim. Não se observou resistência cruzada aos produtos fluazifop, haloxyfop, quizalofop e clethodim.Palavras-chave: resistência, herbicidas, planta daninha, gramínea. ABSTRACT -Among the causes for weed control inefficacy, the worst one is resistance to herbicides. The objectives of this work were to evaluate an Eleusine indica biotype suspected of resistance to ACCase inhibitors and to investigate the occurrence of cross-resistance to several ACCase inhibitors. One biotype of Eleusine indica originated from Mato Grosso with suspected resistance to ACCase inhibitors was evaluated in a greenhouse in relation to

“…Aryloxyphenoxypropionate (APP) and cyclohexanedione (CHD) herbicides are potent inhibitors of acetyl coenzyme A carboxylase (ACCase; EC 6.4.1.2) and are commonly used for the control of various grass weeds. Resistance to ACCase‐inhibiting herbicides in most cases has been attributed to insensitivity of the target enzyme . However, metabolism‐based resistance to ACCase inhibitors has been identified in a comparatively small number of weed species .…”
