Gas chromatographic method has been developed for the determination of metsulfuron methyl residues from soil. Due to the thermal unstability of this herbicide and its mono methyl derivative, it was derivatized to a dimethyl derivative using diazomethane. Structure of the derivatized product was confirmed by GC-MS. Time for methylation reaction was standardized and 24 h was found to be the optimum time in ethylacetate solvent. Using this method, recovery of metsulfuron methyl from soil was above 70%. Limit of detection (LOD) and limit of quantification (LOQ) of the method were 0.1 μg mL⁻¹ and 0.2 μg g⁻¹ respectively.

The ability of some rhizosphere bacteria to mitigate herbicidal stress in cultivated plants may be useful in agriculture and bioremediation. There is poor understanding of how bacteria directly or through herbicide degradation affect the biochemical processes in plants exposed to sulfonylurea herbicides. In this study, treatment with a combination of herbicide metsulfuron-methyl (MSM) and bacteria ( DA1.

Understanding the environmental fate of chemical herbicides is crucial to sustainable agriculture. Due to their joint-use with nitrogen fertilizers, their residues often coexist with NO in agricultural drainages. In this study, tribenuron-methyl was used as a model to evaluate the role of NO in the phototransformation of chemical herbicides, which was characterized by a two-stage process.

Cytochrome P450 monooxygenases (P450s) play important roles in herbicide resistance. In this study, there are four amino acid mutations (F39Y, H163Y, S203A, and V361E) between and , which were cloned, respectively, from susceptible (S) and tribenuron-methyl-resistant (TR) . The Arabidopsis expressing or showed resistance to tribenuron-methyl, carfentrazone-ethyl, and oxyfluorfen, while Arabidopsis transformed with CYP96A146-R or CYP96A146 with any two or three mutations of H163Y, S203A, or V361E exhibited significantly higher resistance to tribenuron-methyl than Arabidopsis expressing CYP96A146-S.

Weed management is an essential intervention for maintaining food security and protecting biodiversity but is heavily reliant on chemical control measures (, herbicides). Concerningly, only one herbicide has been developed with a new mode of action (MOA) since the 1980s. Therefore, alternative strategies for preventing weed growth need to be explored.

Article Synopsis
- Tribenuron-methyl (TBM) is a popular herbicide in Iran for managing broadleaf weeds in wheat due to its low toxicity, effectiveness, and lower cost, but farmers face issues with its performance and resistance.
- A study involving 240 weed populations from 153 wheat fields revealed that over half (51.7%) exhibited resistance to TBM, with specific species like Sinapis arvensis and Malva neglecta showing significant resistance rates.
- This research highlights the growing problem of herbicide resistance in Iranian wheat fields and emphasizes the need for future management strategies to prevent yield loss and environmental harm.
