Know-how through experience

Patented in 1934 – effective pest control for your supplies with PH₃
We are the inventors – and are still leaders in the application and further development of this process today. Our knowledge is based on scientific precision, sound research and practical implementation.
When it comes to PH₃, we don’t just know the theory – we helped write it.

We have the patent. And the knowledge to go with it.

In 1934, our method of pest control with
hydrogen phosphide was patented – a milestone in stock protection.

As the owner of the original patent, we not only have historical pioneering experience, but also a deep scientific understanding of this highly effective process.

Our developments are based on the latest data, international safety standards and extensive research. In close cooperation with leading universities and scientific institutions, we continuously drive the further development of PH₃ applications – safely, efficiently and responsibly.

For us, innovation does not end with a patent. It begins there.
