In the 2021 test year, six AMPs (official means tests) were carried out according to GEP (Guidelines for Good Engineering) standards (Figure 5.3). Five indications were covered in these GEP trials, which meant that 28 new products or combinations could be tested in 51 trial variants on about 5 hectares. Furthermore, a greenhouse test for indications of powdery mildew, as well as two field tests in cooperation with hop growers and the Hopfenring were conducted to check for powdery mildew and common spider mites. In order to generate results and solutions concerning residue problems with fluopicolide (EU standard: reduction to 0.15 ppm) and to generate a pelargonic acid MRL (Maximum Residue Limits) test for Japan, the LfL also conducted residue tests in cooperation with producers of plant protection chemicals. The problem of potential captan residues from Folpan 80 WDG was also part of the test plan. In the 2022 season, further residue tests regarding fluopicolide and Folpan 80 WDG are in the planning stage.
