Biophysical analysis of cuticular permeability for systemic fungicides in berry crops
This research investigates how environmental factors like temperature and humidity affect the cuticular membrane's permeability to systemic fungicides in berry crops, utilizing advanced analytical techniques to optimize fungicide application.
Overview
This innovative research explores how environmental stresses impact the permeability of plant cuticular membranes (CMs) to systemic fungicides, focusing on berry crops. By understanding these biophysical factors, the study aims to enhance the efficiency of fungicide applications, potentially leading to more sustainable agricultural practices and improved crop protection.
Technical specifications
Key methodologies:
- Quantitative analytical workflow: Combines gas chromatography-mass spectrometry (GC-MS) and gas chromatography-flame ionization detection (GC-FID) to analyze chemical changes in CMs due to environmental factors.
- Microscopy techniques: Utilizes cryo-scanning electron microscopy and high-resolution confocal Raman microscopy to examine the structural features and wax deposition patterns in CMs.
- CM isolation protocols: Developed to determine transport parameters such as CM permeances and the transport kinetics of systemic fungicides.
- Fungicide accumulation measurement: Employs QuEChERS extraction protocols and ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) for accurate quantification of fungicide residues in berry tissues.
Technology readiness level
The current research is at Technology Readiness Level 2, indicating that the concept has been formulated and principles have been observed. Further validation is planned through detailed studies on the effects of temperature and humidity on CM parameters in five berry species.
