Understanding the mechanism of photodegradation of agrochemicals on mimetic leaf surfaces using electron paramagnetic resonance spectroscopy: With the ever-rising global population, the needs for efficiency and sustainability in agriculture are increasing. Agrochemicals play a key role in many sustainable farming practices but, when applied to plant surfaces and exposed to sunlight, photodegradation is one key mechanism by which their efficiency can be reduced. The development of better models enabling a more thorough mechanistic understanding of photodegradation processes under realistic conditions will help towards increasing efficiency and sustainability in the development and use of new agrochemicals. In this project, we will investigate the role of the leaf surface and composition in the photodegradation of agrochemicals using electron paramagnetic resonance (EPR) spectroscopy.

利用电子顺磁共振光谱了解农药在模拟叶片表面的光降解机制：随着全球人口的不断增加，对农业效率和可持续性的需求也在增加。农用化学品在许多可持续农业实践中发挥着关键作用，但当应用于植物表面并暴露在阳光下时，光降解是降低其效率的一个关键机制。开发更好的模型，能够更彻底地了解在现实条件下的光降解过程的机理，将有助于提高效率和可持续性，在开发和使用新的农用化学品。在本计画中，我们将利用电子顺磁共振（EPR）光谱技术，探讨叶片表面及组成在农药光降解中的作用。
