Carbonates and Bicarbonates: a Sustainable Approach for Managing Plant Diseases, Pests, and Abiotic Stresses
(Academic Press Ltd- Elsevier Science Ltd, 2025) Turkkan, Muharrem; Ozer, Goksel; Taheri, Parissa; Dervis, Sibel
The growing global food demand necessitates sustainable agricultural practices that minimize environmental impact while ensuring high yields. Synthetic pesticides, while crucial for crop protection, raise concerns about environmental contamination, resistance development, and harm to non-target organisms. Carbonates and bicarbonates (e.g., NaHCO3, KHCO3, CaCO3) offer a promising, Generally Recognized as Safe (GRAS) alternative for integrated pest and disease management and abiotic stress mitigation. These compounds exhibit broadspectrum efficacy against diverse fungal, oomycete, bacterial, and insect pathogens, including the clubroot protist (Plasmodiophora brassicae). Their direct antimicrobial mechanisms involve disrupting pathogen cell membranes and walls, inducing osmotic stress, and altering pH, which leads to pathogen death. Beyond direct toxicity, carbonates and bicarbonates also elicit plant defenses, inducing systemic acquired resistance (SAR) and stimulating defense enzymes (e.g., peroxidase, polyphenol oxidase). Furthermore, they enhance soil health by raising pH, improving nutrient availability, structure, and water retention, while reducing heavy metal bioavailability. These soil improvements increase plant resilience to drought, salinity, and metal toxicity, with potential benefits also arising from improved stomatal regulation. Recent advancements have introduced carbonate nanoparticles as nano-fungicides and biostimulants, offering enhanced efficacy at lower application rates. Integrating carbonates/bicarbonates into Integrated pest management (IPM) programs, especially in combination with biocontrol agents and other beneficial salts, demonstrates synergistic effects and reduces reliance on conventional pesticides. However, further research is needed to elucidate detailed molecular mechanisms, assess long-term soil impacts, optimize application methods (e.g., foliar sprays, soil amendments, nanoformulations), and evaluate compatibility with other agrochemicals. Addressing these knowledge gaps will enable the full potential of these sustainable compounds for resilient and food-secure agriculture.

Environmental Deterioration, Renewable Energy, Natural Resource Rents, and Schooling in Türkiye: Does the Degree of Energy Transition Matter for Environmental Quality?
(Academic Press Ltd- Elsevier Science Ltd, 2024) Bulut, Umit; Atay Polat, Melike; Bulut, Ahsen Seda
Within the literature on energy and environmental economics, it is generally acknowledged that renewable energy can improve environmental quality; however, certain papers suggest that an optimal level of the usage of renewable energy sources may exist. Consequently, the utilization of renewable energy sources can result in environmental degradation up to a certain threshold. Then, environmental quality can be enhanced through the continued application of renewables. This indicates that the link between renewable energy and environmental devastation is inverted U-shaped. This paper presents empirical evidence concerning this possible association between renewable energy and environmental destruction in T & uuml;rkiye, a country where fossil energy predominates in the energy mix. Additionally, the paper investigates the environmental influences of natural resource rents and schooling. This study utilizes annual data from 1971 to 2020 and implements time series methodologies that rely on the Fourier approximation. The paper thus accounts for an undetermined quantity of structural breaks. The results suggest that an inverted U-shaped link occurs between renewable energy and environmental destruction, signifying renewable energy initially contributes to a diminution in environmental quality before subsequently improving it. Additionally, environmental quality is positively associated with natural resource rents and negatively associated with schooling, according to the findings. Furthermore, the findings reveal that schooling worsens the combined effect of renewable energy on environmental degradation. These conclusions are discussed in the paper.

First Report Of Colletotrichum Perseae Causing Anthracnose Disease of Avocado ( Persea Americana) in Türkiye
(Academic Press Ltd- Elsevier Science Ltd, 2024) Bozoglu, Tugba; Turkkan, Muharrem; Ozer, Goksel; Guney, Inci Guler; Dervis, Sibel
Colletotrichum-induced anthracnose is a major disease of avocado (Persea americana), causing significant losses in production worldwide. In 2023, a survey of avocado fruits in markets within the K & imath;z & imath;ltepe district of Mardin, T & uuml;rkiye, revealed symptoms of anthracnose, characterized by brown-black lesions and internal necrosis. To identify the causal agent, 20 symptomatic avocado fruits were collected and fungal isolates resembling Colletotrichum species were obtained. Morphological characterization, multilocus sequence analysis of the internal transcribed spacer (ITS), actin (act), the apn2-Mat1-2 intergenic spacer (ApMat), and calmodulin (cal) loci, and pathogenicity testing were performed for only two representative isolates (Pa01 and Pa02). These analyses identified the pathogen as Colletotrichum perseae. The isolates readily formed ascomata on all culture media tested, suggesting a high capacity for sexual reproduction. Pathogenicity tests confirmed that C. perseae caused characteristic dark, sunken anthracnose lesions on avocado fruits. This is the first report of C. perseae causing anthracnose in avocados in T & uuml;rkiye, expanding the known geographical distribution of this pathogen. The findings highlight the need for effective disease management strategies and further research to understand the pathogen's lifecycle, environmental conditions favoring infection, and potential for seedborne transmission.
