The mutation Asp-376-Glu in the ALS gene confers resistance to mesosulfuron-methyl in Beckmannia syzigachne

Plant Physiology and Biochemistry
Understanding the mechanisms by which weeds develop herbicide resistance is crucial for managing resistance effectively and optimizing herbicide use. Beckmannia syzigachne, a harmful grass weed prevalent in wheat and rice-wheat rotation areas, poses a significant threat to crop productivity.

Fenoxaprop-P-ethyl and mesosulfuron-methyl resistance status of shortawn foxtail (Alopecurus aequalis Sobol.) in eastern China

Pesticide Biochemistry and Physiology, 2018
Resistance to the acetyl-coenzyme A carboxylase (ACCase)- and acetolactate synthase (ALS)- inhibiting herbicides in shortawn foxtail (Alopecurus aequalis) has been reported in wheat fields of eastern China. To better understand the distribution of the resistant populations and the occurrence of the target-site mutations, 74 populations collected from ...

Reduced growth responses of mesosulfuron-methyl-resistant blackgrass to allelopathic wheat are driven by underground chemical interaction

Plant and Soil, 2020
The incidence of herbicide-resistant blackgrass is escalating in wheat fields; the development of alternatives to traditional herbicides is crucial. Allelopathic wheat can suppress blackgrass. Herein, we investigated the influence of allelopathic wheat on herbicide-resistant blackgrass.

Target-site and non-target-site resistance mechanisms confer mesosulfuron-methyl resistance in Alopecurus aequalis

Plant Physiology and Biochemistry
Shortawn foxtail (Alopecurus aequalis Sobol.) is a noxious weed in China. The resistance of A. aequalis developed rapidly due to the long-term application of acetolactate synthase (ALS)-inhibiting herbicides. Here, a suspected mesosulfuron-methyl-resistant A.

Adsorption–desorption behaviour of mesosulfuron methyl and iodosulfuron methyl across soils with varying texture, organic carbon and pH

Environmental Monitoring and Assessment
Mesosulfuron methyl and iodosulfuron methyl are sulfonylurea herbicides widely used for weed control in cereal crops. Despite their low mammalian toxicity, their high-water solubility and weakly acidic nature suggest potential risks regarding their environmental mobility and persistence in diverse agricultural soils, particularly those that are ...

Mechanism of multiple resistance to fenoxaprop-P-ethyl, mesosulfuron-methyl, and isoproturon in Avena fatua L. from China

Pesticide Biochemistry and Physiology
Avena fatua L. is one of the most damaging and malignant weeds in wheat fields in China. Fenoxaprop-P-ethyl, mesosulfuron-methyl, and isoproturon, which belong to Acetyl-CoA carboxylase- (ACCase), acetolactate synthase- (ALS), and photosystem II- (PS II) inhibitors, respectively, are commonly used in wheat fields and have a long history of use on A ...

Deciphering the dual resistance pathways to mesosulfuron-methyl in Lolium multiflorum: target-site and non-target-site insights

Plant Cell Reports
Lolium multiflorum exhibits resistance to mesosulfuron-methyl through ALS mutations; HZ2 population also shows metabolic resistance through P450 pathways. Lolium multiflorum L., is a weed that frequently appears in wheat fields and is recognized for its strong competitive nature, where it can cause significant damage to grain production. The weeds of L.

Modulating Leaching of Mesosulfuron Methyl, Iodosulfuron Methyl and Transformation Products: Effects of Rainfall Intensity, Flow Patterns and Organic Amendments

Bulletin of Environmental Contamination and Toxicology
In light of the environmental pollution risks, the effect of rainfall and flow conditions and addition of farmyard manure on leaching potential of mesosulfuron, iodosulfuron methyl and their transformation products (TPs) was evaluated. Leaching was higher under 300 mm rainfall compared to 150 mm.

One Glutathione S-Transferase Gene, GSTU163, Was Involved in Mesosulfuron-methyl Resistance in Alopecurus japonicus

Journal of Agricultural and Food Chemistry
Alopecurus japonicus, an annual grass damaging wheat and canola fields in China, has evolved resistance to mesosulfuron-methyl, an acetolactate synthase (ALS)-inhibiting herbicide commonly used for its control. In this study, the resistant population (R) exhibited 22.93-fold resistance to mesosulfuron-methyl, and single-dose screening revealed cross ...
