Lolium rigidum, a Pool of Resistance Mechanisms to ACCase Inhibitor Herbicides
Journal of Agricultural and Food Chemistry, 2005Three 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, 2017AbstractBACKGROUNDAcetyl 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 ...

ACCase inhibitor herbicides – selectivity, weed resistance and fitness cost: a review
International Journal of Pest Management, 2013The 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.

Mapping risk areas for resistance to ACCase inhibitor herbicides in Manitoba
Canadian Journal of Plant Science, 1997Since 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 Herbicide Resistance in Downy Brome (Bromus tectorum) in Oregon
Weed Science, 2007In spring 2005, a downy brome population with possible resistance to fluazifop-P, an acetyl-CoA carboxylase (ACCase) inhibitor (group 1) herbicide was found in a commercial creeping red fescue seed production field, near La Grande, OR, where fluazifop-P had been used to control downy brome repeatedly over 7 yr.

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 ...

Target-Site Based Resistance to Accase Inhibitors
1997The 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 ...

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 ...

Cross-Resistance of Japanese Foxtail (Alopecurus japonicus) to ACCase Inhibitors in China
Weed Technology, 2015The increasing use of ACCase-inhibiting herbicides has resulted in evolved resistance in key grass weeds infesting cereal cropping systems worldwide. Japanese foxtail is one of the most important grass weed species in wheat in China. Most populations have evolved resistance to fenoxaprop-p-ethyl, which is one of the most common ACCase-inhibiting ...
