In recent years the importance of adjuvants for optimising the activity of agrochemicals has become increasingly recognized. This book is aimed at accumulating the current knowledge of the interactions between adjuvants, agrochemicals and target organisms. It provides results, and ideas for future research and defines new methodological, biomechanistic and systematic approaches which can be implemented to streamline research and development of formulations and adjuvant/active ingredient combinations. The book contains micrographs of leaf surfaces and spray deposits, graphical and statistical presentations, and data on the properties of adjuvants. In particular a case study is presented demonstrating the interactions possible between formulation and adjuvant types.
