Summary: Resistance to ACCase-inhibiting herbicide pinoxaden in a population of L. perenne is characterized by the concurrent action of cytochrome P-450 activity enhancement and a rare target-site mutation. The resistant population showed different levels of resistance to other herbicides but remained susceptible to clethodim.

Summary: The Lolium genus includes several important plants that are of particular interest to weed scientists due to their ability to thrive in both agricultural and non-agricultural environments, and have evolved resistance to multiple herbicide mechanisms. This review summarizes the current knowledge on non-target-site resistance in Lolium spp. to various herbicide mechanisms and suggests further research topics and strategies to enhance our understanding of resistance mechanisms.

Summary: In this study, the efficacy of a new triazinone-type inhibitor, trifludimoxazin, in inhibiting PPO2 enzymes carrying target site mutations was assessed. The results strongly suggest that trifludimoxazin is a potent PPO-inhibiting herbicide. This study is of significant importance for the design of new herbicides to control resistant weeds.

Summary: Resistance to iodosulfuron, an herbicide targeting acetolactate synthase (ALS), was identified in a population of Lolium perenne L. from Canterbury, New Zealand. The resistance was due to enhanced herbicide metabolism and a target-site gene mutation. This study provides insights into the resistance mechanisms of ALS-inhibiting herbicides in Lolium perenne and highlights the importance of integrated weed management approaches.

Summary: This study aims to determine the resistance pattern of Italian ryegrass to acetolactate synthase inhibiting herbicides in wheat fields in Turkey and proposes solutions to address the problem. The research findings show that some biotypes of Italian ryegrass exhibit resistance to herbicides and have high resistance levels. Amino acid substitution mutations were also detected. The study highlights the need for diversified resistance-management strategies and the development of global policies to mitigate weed resistance.

Summary: The study identified resistance of Alopecurus myosuroides to pyroxsulam in Chinese winter wheat fields, with resistance conferred by specific mutations in the ALS gene. Resistant populations displayed moderate resistance to pyroxsulam compared to susceptible populations.

Summary: Understanding the diversity of polyploid Echinochloa spp. resistant to ALS inhibitors in Italian rice fields is crucial for resistance management. Molecular characterization revealed the presence of specific ALS gene mutations in E. crus-galli and E. oryzicola, contributing to their high herbicide resistance levels.

Summary: This study explores the diversity of non-target site resistance (NTSR) mechanisms in common ragweed populations from different regions in France. Transcriptome analysis identifies a wide range of genes associated with NTSR and reveals population-specific evolution in response to herbicide selective pressure. The findings contribute to a better understanding of the complexity and diversity of NTSR mechanisms.

Summary: Herbicide resistance is a significant issue in weed management. Glyphosate is the dominant herbicide used and controls a wide range of weeds, including Lolium rigidum. Some populations of L. rigidum in Australia have developed resistance to glyphosate and can now grow throughout the summer. The resistance of three L. rigidum populations, including a glyphosate-resistant summer-emerging population, a glyphosate-susceptible winter-emerging population, and a winter-emerging population with unknown resistance status, was analyzed. The analysis showed that the summer-emerging glyphosate-resistant population was significantly more resistant to glyphosate than the winter-emerging glyphosate-susceptible population. However, no target-site mutations were found in the resistant population, suggesting non-target-site resistance.

Summary: In this study, the herbicide resistance of three winter annual grasses was investigated in winter wheat production areas in Colorado. Three imazamox-resistant populations of feral rye were identified, with two populations having target-site mutations and one population showing enhanced metabolism. This research provides the first report of both target-site and metabolism-based imazamox resistance in feral rye.

Summary: The weed Lolium rigidum in Spain shows resistance to ALS and ACCase inhibiting herbicides, as well as reduced sensitivity to other chemistries. Resistance to ACCase inhibitors is linked to specific point mutations in the enzyme, while non-target-site resistance may also play a role. The study highlights the urgent need to monitor and prevent further evolution of herbicide resistance in L. rigidum in Mediterranean areas.

Summary: Susceptible and putative FPB-resistant barnyardgrass biotypes were selected based on dose-response tests, with resistant biotypes showing reduced FPB absorption and lower production of the active metabolite florpyrauxifen-acid. Sequencing of TIR1 and AFB genes showed no differences between susceptible and resistant biotypes. These results suggest that metabolic pathways may play a role in barnyardgrass resistance to FPB.

Summary: This study elucidated the molecular basis of resistance to the ALS inhibitor nicosulfuron in crabgrass populations from different provinces in China. The resistance was found to be mainly due to the overexpression of the ALS gene and possible metabolic resistance.

Summary: Soil erosion caused by land use change is a major issue in agricultural areas. This study conducted an in-field experiment in Northern Thailand to examine the effects of catena position and biochar use on seed displacement, soil loss, and nutrient losses. The results showed that catena position and biochar had an impact on runoff, soil and nutrient losses. The reappearance of biochar at the soil surface and its effects on runoff, nutrient concentration, and seed displacement were also observed. The study highlights the differences in soil surface features and runoff along the catena under tropical climate and steep slope conditions, and suggests considering catena position for improving soil management and adopting appropriate agroecological practices.

Summary: This study investigated the occurrence and resistance level of quinclorac-resistant barnyardgrass in Thailand, as well as alternative control measures. The findings showed that quinclorac-resistant barnyardgrass was widely distributed in major rice-production areas of Thailand, with some populations exhibiting multiple resistance to other herbicides.
