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.

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 ...

Response of the Resistant Biotype of Echinochloa oryzoides to ACCase and ALS inhibitors, and Effect of Alternative Herbicides [PDF]

Korean Journal of Weed Science, 2010
*, Bon-Il Ku, Sin-Koo Kang, Min-Kyu ChoiHong-Kyu Park, Kyong-Bo Lee and Jae-Kwon KoABSTRACT Cyhalofop-butyl and penoxsulam, known for respective acetyl CoA carboxylase (ACCase) and acetolactate synthase (ALS) inhibitor, have been widely using as a post-emergence foliar application for many years in wet-seeded rice field in Korea. Since 2009, control of

Effect of Glyphosate and Several Accase-inhibitor Herbicides on Wirestem Muhly (Muhlenbergia Frondosa) Control

Weed Technology, 2007
Field and greenhouse studies examined glyphosate and several ACCase-inhibitor herbicides for control of wirestem muhly. A field study evaluated application rate and timing for control in glyphosate-resistant soybean. Herbicides were applied at two rates, 4 and 6 wk after planting (WAP) of soybean when wirestem muhly was about 30 and 50 cm tall ...

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 ...

Origin of Enantiomeric Selectivity in the Aryloxyphenoxypropionic Acid Class of Herbicidal Acetyl Coenzyme A Carboxylase (ACCase) Inhibitors

Journal of Agricultural and Food Chemistry, 2002
Molecular modeling was used to propose an "active conformation" for the R-2-phenoxypropionic acid portion of the aryloxyphenoxypropionic acid series of herbicidal acetyl CoA carboxylase (ACCase) inhibitors. This candidate active conformation is a low-energy conformer with the R-methyl distal to the phenoxy fragment, stabilized by the generalized ...

Structure–activity relationships of pheromonostasis induced by ACCase-inhibitor herbicides in the moth Helicoverpa armigera

Pesticide Biochemistry and Physiology, 2008
Abstract Many moth sex pheromone blends are derived from fatty acids and their production is regulated by a Pheromone Biosynthesis Activating Neuropeptide (PBAN). In prior work we showed that the herbicide Diclofop-acid, an acetyl-coenzyme A carboxylase (ACCase) inhibitor, inhibits PBAN-induced sex pheromone production in vitro .
