The Du Roi group of companies is privately owned and had its beginnings in 1989 as a citrus nursery, located near Letsitele in the Limpopo Province, Republic of South Africa. Since then the group has expanded to include five operational businesses focusing on mass production and distribution of superior selections and disease free plant material (with its primary focus on citrus plants, banana- and sugar cane- tissue culture plants), the breeding of beneficial insects for biological pest control and a number of support businesses to assist and develop previously disadvantaged black farming communities. Through this focused involvement, together with its support services, financial instruments and drive for improved technologies, Du Roi is well positioned to influence developments in the subtropical fruit industry and has the potential to play an increasingly influential role in ensuring the continued global competitiveness of a number of other subtropical fruit sectors in Africa.

Du Roi Nursery was established in 1989. The nursery is fully accredited with the SA Citrus Improvement Program and produces quality, certified citrus, mango, pomegranate and guava trees. Du Roi Nursery provides extensive technical support to local and international customers.
Du Roi Laboratory was established in 1994 and specializes in the production and distribution of disease-free, virus-indexed tissue culture banana plants. These plants are multiplied from superior selections obtained from an extensive breeding programme. Du Roi Laboratory provides extensive technical support to local and international customers.
Du Roi IPM was established in 1999 and specializes in the breeding and trading of predatory and parasitic insects (beneficial insects) for the control of agricultural pests. Du Roi IPM provides extensive technical support to local and international customers.
Du Roi - New Projects As the Du Roi companies pride themselves in focused, dedicated and professional products and services, the development of new businesses and technologies needs to be managed on a project level until they are ready to operate as stand alone companies.
