Yield and cost–benefit analyses for apple scab sanitation practices in integrated and organic apple management systems

PLANTS, PEOPLE, PLANET, Volume 6, Issue 2, Page 470-489, March 2024.
Reduced fungicide use lowers environmental pollution and enable safer food production. The usage of fungicides can be reduced by applications of sanitation practices, which decrease the inoculum sources of apple scab disease on fallen leaves. Our study showed that two non‐chemical sanitation practices, namely the collection of fallen leaves ‘CFL’ and ...

Face‐Centered Central Composite Design for the Optimization of the Extraction of Phenolic Compounds from Kernels and Shells of Raphia farinifera and Evaluation of the Antioxidant, Antimicrobial, and Anti‐Inflammatory Activities

Journal of Food Processing and Preservation, Volume 2024, Issue 1, 2024.
This study reports the extraction of phenolic compound from shells and kernels of the Raphia farinifera fruit and the biological activities of the extract. A face‐centered composite design was established to optimize the extraction conditions: ethanol/water ratio (0‐100%), solvent/powder ratio (10‐30 mL/g), and extraction time (90‐180 min ...
