An analysis of the impact of accession to the European Union and implementation of compulsory integrated pest management on the chemical protection of forest in Poland against diseases and weeds was performed. No impact of compulsory integrated pest management has been observed on forest protection against diseases and weeds so far. However a strong influence of the legal changes and implementation of common registration rules on the availability of plant protection products was observed.The paper presents data on the fungicides and herbicides use in Polish forests in the years 1997–2017. Protection against weeds and diseases in Poland is focused only on very young trees. Consequently the application of herbicides and fungicides is performed on much smaller area than application of insecticides and never from the air. In terms of volume, the use of fungicides and herbicides in Polish forests in the year 2017 was below 0,1% of fungicides and herbicides used at the same time in Polish agriculture.
