This is not only German propaganda, but also Chapter 9 (if my memory serves me correctly) of Mein Kampf. Slavs are described as a resource for colonization and slaves for future German masters. Slavs in German propaganda were often equated with Gypsies and portrayed as a threat to white German culture. The Slavs also had a hierarchy in German foreign policy, with the Eastern Slavs considered the lowest, the Poles, Croats, and some others considered less lowly, and used as German tools in difficult regions.
The Finno-Ugrians were also considered representatives of the yellow race, long before Hitler, in the works of the Frenchman Arthur de Gobineau, one of whom he was inspired by in racial theory.
