Latvian State Plant Protection Centre

After regaining independence, the institution returned under the authority of the state of Latvia.

In 2000, in accordance with the requirements of the European Union directives, the Regulations on Good Experimental Practice in Latvia were developed so that the results obtained in the experiments could be used in all countries of the Baltic Sea region.
