Summary: This study investigated the mechanism of resistance to the herbicide 2,4-D in a Palmer amaranth population collected from a conservation tillage field. The results showed that the resistance was primarily mediated by enhanced metabolism of 2,4-D.

Summary: This study focused on a clopyralid-resistant population of S. sessilis collected from a golf course with a long history of clopyralid applications in New Zealand. The resistant phenotype was highly resistant to clopyralid and also exhibited cross-resistance to dicamba, MCPA and picloram. The resistant individuals had fewer lobes on their leaves, were slightly larger, had a larger leaf area, and greater root dry weight compared to susceptible plants.

Summary: The weed Carduus acanthoides L. has started invading GM crop production systems in Argentina, where glyphosate and 2,4-D are commonly used herbicides. In 2020, a population of C. acanthoides was found to have multiple resistance to both herbicides. The resistance mechanism for glyphosate was a Pro-106 mutation in the EPSPS gene, while resistance to 2,4-D was due to enhanced metabolism mediated by cytochrome P450. This is the first reported case of resistance to glyphosate and 2,4-D in C. acanthoides worldwide.

Summary: This study evaluated the dynamics of 2,4-D and dicamba in corn straw and their relationship with residual control of weeds. The leaching of the herbicides from the straw was influenced by rainfall amount and drought period, and the presence of the straw exerted a significant physical control effect on weeds. Furthermore, the efficacy of 2,4-D and dicamba varied in controlling different weed species in the absence of straw.

Summary: This study focused on the adsorption of 2,4-dichlorophenoxy acetic acid (2,4-D) from aqueous solutions using activated carbon produced from orange pulp. The experimental data showed that the prepared activated carbon has good potential for the removal of 2,4-D from aqueous solutions.

Summary: This study investigates the impact of dicamba off-target movement on sensitive crops, including cucumber, eggplant, and snap bean. It reveals that cucumber is not significantly affected, eggplant is moderately impacted with some yield reduction, and snap bean is highly sensitive with significant yield loss.

Summary: The drift of auxinic herbicides 2,4-D and dicamba has different effects on crops, soil microbiota, and weeds. Dicamba is more toxic to mandarin seedlings, but both herbicides affect the physiological processes of plants.

Summary: This study aimed to investigate the interaction between a new auxinic herbicide and indigenous plant hormones. The findings suggest that different growth conditions, temperatures, and growth stages have varying effects on plant hormone responses. Additionally, transcriptome analysis revealed distinct expression patterns after treatment with different auxinic herbicides, indicating the involvement of specific genes in the auxin response.

Summary: The occurrence of freezing stress has an impact on the efficacy of clodinafop-propargyl and 2,4-D plus MCPA herbicides. Under freezing conditions, the recommended doses of these herbicides were effective in controlling winter wild oat and turnipweed.

Summary: Previous studies have characterized the resistant plants of Sumatran fleabane with rapid necrosis symptoms after applying 2,4-D. This study aimed to investigate the causes of variability in the occurrence of the rapid necrosis and found that environmental conditions, plant growth stage, and herbicide interactions can interfere with the symptoms. The herbicides dicamba and triclopyr effectively controlled resistant plants, especially when sprayed at the initial growth stages, providing insights into the mechanisms and causes of herbicide symptomology and performance variability.

Summary: A new electrochemical method for determining 2,4-dichlorophenoxyacetic acid (2,4-D) in aqueous solutions was proposed. The glassy carbon electrode was modified and characterized with various techniques, and the electrochemical attributes of 2,4-D at different pH values were studied. Additionally, the modified electrode showed low detection limit, high linear range, and good repeatability, making it suitable for the analysis of 2,4-D in water samples.

Summary: Multiple herbicide-resistant (MHR) kochia is a serious concern in the U.S. Great Plains and alternative herbicide mixtures are needed for its control. The study found that mixing dicamba with other auxinic herbicides in two- or three-way mixtures can help control MHR kochia and result in synergistic effects. This was observed in both greenhouse and field experiments.
