Summary: This study aimed to produce low-cost activated carbon (AC) from corn stigmata (CS) through chemical activation at low temperatures using H3PO4, ZnCl2, and KOH. The results showed that activation with phosphoric acid resulted in an adsorbent with a larger specific surface area and high pore size. Increasing the activation temperature from 200 to 500 degrees C led to the development of surface functions, a mixture of meso and microporosity, and a significant increase in specific surface area. The physicochemical and textural properties of ACs were analyzed using various techniques, and the adsorption process of methylene blue (MB) was well described by mathematical models. The maximum adsorption capacity for MB was found to be high compared to previous literature.

Summary: The developments of information and automation technologies have opened up new possibilities for weed management in agricultural fields. Site-specific weed management systems, utilizing sensor technologies and artificial intelligence, have shown ecological and economic benefits in controlling weeds. Challenges exist in terms of interoperability of sensing and controllers, but the adoption of standards could improve the implementation of these technologies. Further on-farm research is needed to integrate these technologies into agricultural practice. Overall, the potential impact of site-specific weed management in reducing pesticide use and increasing biodiversity is significant.

Summary: The study found that feed-grade soybean cultivars were better adapted to the central European climate compared to food-grade cultivars, providing higher and more stable yields. Irrigation increased soybean grain yields by an average of 41%, with no additional irrigation required in years with sufficient rainfall. Gross margins for organic soybean were higher than other crops, indicating a large agro-economic potential for soybean cultivation in central Europe as a novel grain legume crop.

Summary: Cold stress significantly affects plant development and crop yield. Temperate plants have the ability to acclimate to low temperatures, while plants from tropical origins are more sensitive to cold stress. Plants have evolved various mechanisms to sense and respond to low-temperature stress, with epigenetic control playing a crucial role.

Summary: Bactericides, fungicides, and other pesticides play a crucial role in managing plant diseases, but their use can lead to harmful residues on plants and in the environment. The increasing resistance of plant pathogens to certain chemicals, such as streptomycin and fungicides, poses a significant concern. Additionally, the rise of environmental triazole fungicide-resistant Aspergillus fumigatus, which causes aspergillosis in humans, is particularly alarming in Europe. Through horizontal gene transfer, resistance genes can be exchanged among various bacteria in the agricultural setting, including plant pathogens and zoonotic bacteria. This can result in cross-resistance and even multi-drug resistance to different compounds. To ensure food security, sustainable production, and minimize the emergence and transmission of antimicrobial-resistant organisms from horticultural sources, the responsible use of pesticides is crucial.
