Sensitivity to demethylation‐inhibiting fungicides and induced expression of CYP51 associated with tebuconazole resistance in Alternaria species on mandarin in Brazil

open access: yesPest Management Science, EarlyView.
Tebuconazole‐resistant isolates overexpress CYP51 and, when tested at field rates, did not reduce ABS severity, whereas difenoconazole and mefentrifluconazole remained effective. Abstract BACKGROUND Alternaria brown spot (ABS), caused by Alternaria spp., is an important disease affecting mandarin production in several citrus‐growing regions worldwide ...

Chemical Characterization of Postindustrial Recycled Polyethylene Terephthalate Obtained From Multilayer PET/PE Sheets: A Baseline Study on Safety Aspects

open access: yesPackaging Technology and Science, EarlyView.
PET trays pose recycling challenges due to multilayer structures with polyethylene (PE) tie‐layers and barrier materials. In this study, a delamination process using a hot alkaline solution was applied to postindustrial multilayer PET/PE thermoforming waste to recover PET flakes and produce sheets.

Anti‐Globalization Dynamics and Africa's Structural Transformation: Identifying Avoidable Environmental Degradation Thresholds

open access: yesSustainable Development, EarlyView.
ABSTRACT This study pursues a dual objective. First, it investigates the unconditional impact of anti‐globalization on structural transformation in Africa. Second, it explores how environmental degradation interacts with anti‐globalization to influence structural transformation. The analysis focuses on 52 African countries over the period 2005–2023. To
