About Devgen nv

Devgen’s mission is to enable farmers to sustainably grow more food on less land, with less water, agrochemicals and labour.

Devgen uses advanced biotechnology and molecular breeding technology to make high yielding seeds and crop protection solutions with a superior environmental profile.

Devgen brings this technology to the market in the world’s major food and feed crops through two complementary strategies:

- Licensing Devgen technology for use in corn, cotton and soy and selected other crops in exchange for R&D funding, and milestone and royalty payments.

- Producing and selling its premium hybrid seeds in major field crops such as rice, sunflower, sorghum, and pearl millet, in the Indian subcontinent and South-East Asia.

In its Crop Protection unit, Devgen developed an agro-chemical product that protects crops from damage by parasitic nematodes. This nematicide was launched in Turkey and in US.

Incorporated in 1997, Devgen has offices in Ghent (Belgium), and has subsidiaries in Singapore, Hyderabad (India), General Santos (Philippines) and Delaware (US), totaling about 280 employees.
