                        Computing the Pesticide Load Indicator for
                        pesticide application data The provided
                        functions will compute the Pesticide Load
                        Indicator (PLI) as described in Kudsk et al.
                        (2018) for pesticide application data provided
                        by the user. Computing the PLI requires
                        information on applied pesticides in a table
                        format, as well as information on fate,
                        ecotoxicity and human health properties of
                        applied pesticide products, as provided in the
                        Pesticide Properties Database (PPDB) of the
                        University of Hertfordshire. See below for a
                        detailed description. The PLI can either be
                        computed using user supplied information on
                        pesticide properties or by automatically
                        including the information based on the PPDB.
