Summary: This study investigates the pore structure characteristics of coal samples from different mines using nuclear magnetic resonance technique, and conducts displacement experiments of CO2 in water-saturated coal seams. The results show that CO2 can occupy the adsorption sites on the coal surface, reducing the interaction between water and coal and improving the displacement efficiency. It is also found that in the water injection stage, CO2 retention and adsorption result in water only entering larger pores.

Summary: This study investigated the influence of long-term conventional tillage on the water-physical, chemical properties, and composition of chernozems. The results showed that tillage deteriorated the water-physical properties of the soil and affected the organic matter composition. The study also found that long-term plowing decreased aliphatic structures and increased aromatic structures in soils. To improve soil fertility and carbon sequestration potential, it is important to implement conservation tillage practices and prevent degradation processes.

Summary: Quantum entanglement is a unique form of correlation between quantum particles that cannot be increased through local operations and classical communication. The presence of entanglement gain between detectors interacting through a classical mediator suggests non-classical characteristics of the mediator. Research indicates the significance of the initial state in determining the entanglement gain between detectors.

Summary: The commercialization of 2,4-D-resistant soybean varieties has led to increased use of 2,4-D herbicides in soybean crops. However, this study found that the reliance on 2,4-D herbicides resulted in shifts in weed populations, with an increase in weed species tolerant to 2,4-D. By using diversified herbicide strategies with more than three sites of action, weed density can be reduced and the shift in weed populations can be delayed.

Summary: Cover crops can suppress weed growth through direct competition for sunlight, water, and soil nutrients, benefiting soybean cropping systems. Delaying termination of cover crops can lead to increased biomass but may result in yield reductions. Cover crops generally improve weed control in the absence of 2,4-D, but may not reduce densities of all weed species.

Summary: Water quality, including pH, hardness, temperature, and turbidity, can affect the performance of herbicides. Different herbicide chemistries and weed species respond differently to water quality factors. Weak-acid herbicides are more effective in acidic water, while sulfonylurea herbicides are negatively impacted. The temperature of the spray solution should be between 18°C and 44°C for optimal efficacy. Water turbidity has a severe effect on cationic herbicides and herbicides with low soil mobility. Adjuvants can be used to mitigate the negative effects of water hardness or pH, but their response varies.

Summary: Herbicide mixtures are commonly used to control a wide range of weeds, including those resistant to specific herbicides. However, the impact of mixtures on the evolution of herbicide resistance through enhanced metabolism is not well understood. In this study, the effects of a fenoxaprop-p-ethyl and imazethapyr mixture on herbicide resistance evolution in Echinochloa crus-galli were evaluated. Results showed that recurrent selection with the mixture led to decreased control and increased resistance to several herbicides. Additionally, it was found that the main contributor to decreased control was fenoxaprop. This study highlights the need for using fully recommended herbicide rates in mixtures to reduce the risk of resistance evolution.

Summary: A physiological rapid response was found in a biotype of Conyza sumatrensis, which may contribute to its resistance to 2,4-D herbicide. The resistance is mainly attributed to the reduced translocation of 2,4-D in the plants. The resistant plants also show lower metabolic capacity for 2,4-D compared to the susceptible plants.

Summary: Herbicide resistance in weeds is an evolutionary process that leads to the convergence of similar resistance mechanisms in geographically distant weed populations. Amaranthus species show remarkable ability in evolving resistance and invading new environments globally. North America and South America have different cases of herbicide-resistant Amaranthus species, with around 70% of them reported in global soybean and corn crops. Multiple herbicide resistance mechanisms are evident in weed species. Seed-mediated gene flow plays a crucial role in the spread of herbicide-resistant Amaranthus species populations. The reduction of herbicide selection intensity through diverse and integrated weed control practices should be a common goal in weed management programs.

Summary: RNA interference (RNAi) is a promising technology for weed management, which involves spraying small RNAs (sRNAs) to induce gene silencing without the use of transgenes. However, the development of this technology in weed science has been slower compared to other crop protection areas due to the challenges in synthesizing stable sRNAs and ensuring their effectiveness. Once these challenges are overcome, RNAi technology could become a valuable tool for weed management and herbicide resistance management.

Summary: This study investigates the effect of reduced temperature on the content and metabolism of quizalofop in resistant wheat and three weed species. The results show that cooler temperatures delay the metabolism of quizalofop, but do not reduce the absorption and de-esterification process. The final herbicide efficacy may not correspond to differences in metabolism, and weed biomass differs at different temperatures.
