The Southern African Macadamia Growers’ Association (SAMAC) and the Forestry and Agricultural Biotechnology Institute (FABI) has established a collaborative research partnership to address the threats posed to Macadamia farming in South Africa by pests and diseases.

South Africa is the second largest macadamia nut producer in the world and the industry is regarded as the fastest growing tree crop industry in the country. The industry, however, is hampered by a number of pests and diseases, which can cause significant economic losses. In addition, the continuous build-up of resistance towards commercially available pesticides and chemicals is of concern to growers.

In order to ensure the long-term sustainability of the Macadamia industry, growers need to move towards alternative control and management strategies. The overall focus of the Macadamia Protection Programme will be to assist in the development of commercially viable biological control options, as well as alternative management strategies. More specifically, this research programme will focus on the development of biologically relevant information on important pests and pathogens, in order to improve integrated pest management systems. The programme will also aim to contribute to the development of biological control agents and natural products, as well as to conduct research that assist in the selection of resistant or tolerant cultivars.
