The effectiveness of pesticides (including herbicides, fungicides and insecticides) for crop protection crucially depends on the permeability of the formulation's active ingredient across various leaf layers and membranes. Chemical adjuvants are often used to soften the top wax layer of the leaf and enable herbicide transport across this protective barrier. In practice the link between active ingredient uptake, wax softness and/or permeability and the effectiveness of a herbicide is very challenging to measure. Engineering effective adjuvants and understanding the gains and losses in efficacy are, therefore, significant agrotech challenges.This project is a collaboration between BASF and the Institute of Chemical Biology EPSTC Centre for Doctoral Training, and will develop a suite of novel methods to measure wax softening and permeability in two complementary ways:1. direct imaging of permeability of highly controllable wax barrier in droplet interface bilayer tool; and,2. via directly imaging of wax viscosity using environmentally sensitive molecular rotors and advanced optical microscopy.

农药（包括除草剂、杀菌剂和杀虫剂）对作物保护的有效性主要取决于制剂活性成分在不同叶层和膜上的渗透性。化学助剂通常用于软化叶子的顶部蜡层，并使除草剂能够穿过该保护屏障。在实践中，活性成分的吸收、蜡的柔软度和/或渗透性与除草剂的有效性之间的联系非常难以测量。因此，设计有效的助剂并了解功效的得失是农业技术面临的重大挑战。该项目是巴斯夫与化学生物学研究所 EPSTC 博士培训中心的合作项目，将开发一套测量蜡软化的新方法和渗透性以两种互补的方式：1。液滴界面双层工具中高度可控蜡屏障渗透率的直接成像；以及，2。通过使用环境敏感的分子转子和先进的光学显微镜直接对蜡粘度进行成像。
