Integrated Pest Management (IPM) refers to the integration of all available techniques for control of diseases, harmful insects and weeds and keep the use of pesticides to levels that are economically justified and environmentally sustainable (FAO, 2016). In compliance with regulations 2009/128/EU and 2009/1107/EU, the five Nordic countries, UK, the Netherlands, Germany, Portugal and Italy have all imposed strict regulations on pesticide use (STERF, 2016). In this context, a main challenge for golf courses is to secure high-quality playing conditions for current and future generations while at the same time reducing the dependency on chemical plant protection products. IPM has for many years been one of STERF’s highest research priorities with a focus on: Evaluation and management of turfgrass species, varieties and mixtures to create more disease resistant, stress tolerant and weed-competitive turf (i); Identification and understanding the biology and proliferation of harmful organisms in turf (ii) Safer and more efficient use of pesticides (including reduced risk for surface runoff and leaching to the environment (http://www.sterf.org/sv/projects/project-list?pid=12) (iii). Due to common EU directives, global warming and other reasons, golf courses in other parts of Northern Europe mostly experience the same IPM challenges as in the Nordic countries. This project addresses UN’s Sustainable Development Goals 12, 13 and 15 as described by R&A and STERF in ‘Golf Course Scandinavia 2030’. It is also a direct follow-up of R&A’s GC2030 ‘Action Plans for ‘Golf Course Condition and Playability’ (1) and ‘Resources’ which request projects that identify alternative approaches to pesticide use and discuss their efficacy (2). The overall goal of this project was to investigate cultural practices and new technologies for prevention and control of the two most important and destructive turfgrass diseases on golf course putting greens - microdochium patch and dollar spot, and to get insight on situation and methods for prevention and control of insect pests on golf courses with a minimum use of pesticides in the Nordic countries.
