Characterisation and management of Phalaris paradoxa resistant to ACCase-inhibitors

Crop Protection, 2011
Phalaris paradoxa is a competitive grass commonly found in durum wheat crops of central and southern Italy. Among the 85 populations screened from 1998 to 2008 for resistance to ACCase-inhibitors and graminicide sulfonylureas, 17 resulted as being resistant to at least one ACCase inhibitor while none of the populations showed resistance to ...

Use of Resistant ACCase Mutants To Screen for Novel Inhibitors against Resistant and Susceptible Forms of ACCase from Grass Weeds

Journal of Agricultural and Food Chemistry, 2004
The aryloxyphenoxypropionic acid (AOPP) and cyclohexanedione (CHD) herbicides inhibit the first committed enzyme in fatty acid biosynthesis, acetyl CoA carboxylase (ACCase). The frequent use of AOPP and CHD herbicides has resulted in the development of resistance to these herbicides in many grass weed species.

Weeding Effect of Echinochloa oryzoides Resistant to ACCase and ALS Inhibitors by the Leaf Stages

Korean Journal of Weed Science, 2011
ABSTRACT Weeding effect was investigated based on the leaf stages to several different herbicide treatments for an integrated weed management of herbicide resistant Echinochloa oryzoides to ACCase and ALS inhibitors in a rice field. Efficacy of soil-applied herbicide treatments before resistant E. oryzoides occurred was very effective. Pentaxazon 5% SC

Target-Site Based Resistance to Accase Inhibitors

1997
The enzyme acetyl-coenzyme A carboxylase (ACCase; E.C. 6.4.1.2) is the target site of two major groups of synthetic herbicides, the aryloxyphenoxypropanoates (AOPP) and cyclohexanodiones (CHD). ACCase is a key enzyme in the biosynthesis of acyl lipids, catalyzing the addition of HCO 3 - to acetate to form malonate, a precursor of fatty acid ...

Lolium rigidum, a Pool of Resistance Mechanisms to ACCase Inhibitor Herbicides

Journal of Agricultural and Food Chemistry, 2005
Three diclofop-methyl (DM) resistant biotypes of Lolium rigidum (R1, R2, and R3) were found in different winter wheat fields in Spain, continuously treated with DM, DM + chlortoluron, or DM + isoproturon. Herbicide rates that inhibited shoot growth by 50% (ED50) were determined for DM.

Basis of ACCase and ALS inhibitor resistance in Hordeum glaucum Steud

Pest Management Science, 2017
AbstractBACKGROUNDAcetyl coenzyme‐A carboxylase (ACCase) and/or acetolactate synthase (ALS) inhibitor resistance has been identified by herbicide resistance screening in eight populations obtained from cropping regions of South Australia. This study aimed to quantify the level of resistance and characterise the molecular basis of resistance to ACCase ...

Mapping risk areas for resistance to ACCase inhibitor herbicides in Manitoba

Canadian Journal of Plant Science, 1997
Since 1976, seven acetyl coenzyme-A carboxylase (ACCase) inhibitors (referred to as Group 1 herbicides) have been registered in western Canada for wild oat (Avena fatua L.) and green foxtail (Setaria viridis L.) control. In 1990, Group 1 resistant wild oat populations were identified from fields in Manitoba which had been repeatedly sprayed with these

ACCase inhibitor herbicides – selectivity, weed resistance and fitness cost: a review

International Journal of Pest Management, 2013
The worldwide application of the group of herbicides known as ACCase inhibitors is associated with the widespread appearance of resistant biotypes among weeds. Accordingly, ACCase inhibitor resistance has become the third most frequent type of weed resistance.

Molecular basis of ALS- and/or ACCase-inhibitor resistance in shortawn foxtail (Alopecurus aequalis Sobol.)

Pesticide Biochemistry and Physiology, 2015
Alopecurus aequalis, a predominant weed species in wheat and oilseed rape fields, can no longer be controlled by mesosulfuron-methyl application after continuous use over several years. Based on dose-response studies, the putative resistant populations, JTJY-1 and JHHZ-1, were found to be resistant to mesosulfuron-methyl, with resistance index values ...

Synthesis of an indolizidinedione oxime inhibitor of acetyl-coenzyme a carboxylase (ACCase)

Bioorganic & Medicinal Chemistry Letters, 1994
Abstract The synthesis and enzyme inhibitory activity of a novel hybrid compound which incorporates substructures of two classes of inhibitors of ACCase are described.
