PPRI.png

The Plant Protection Research Division focusses on ecologically sound management strategies for agricultural pests, plant diseases and invasive plants, and promote the use of advantageous organisms to strengthen agricultural production in a sustainable way, through research, technology development and technology transfer.


ARC-PPRI was established in 1962 with the amalgamation of the Divisions of Entomology and Plant Pathology of the Department of Agriculture. These Divisions had been in existence since Unification in 1910. In 1981 research on invasive weeds was formally added to the ARC-PPRI and during 2000 the Agricultural Biodiversity Information Unit joined the institute. This multidisciplinary Institute follows a holistic approach to the pest, disease and alien invasive plant problems, in line with the principles of integrated pest management as defined in Agenda 21 of the Rio Convention.  [Read more

Research Programmes

Biosystematics.png
Biosystematics

​At the Biosystematics Division we conduct systematic and ecological research on economically and environmentally important groups of arthropods, nematodes and fungi. We are also the custodians of the South African National Collections of Arachnida, Fungi, Insects and Nematodes, which form an invaluable basis for taxonomic research and services and an archive of the country's biological diversity.  Through our wide-ranging taxonomic expertise and extensive reference sources we are able to provide comprehensive biosystematic advisory services and products to the research community concerned with agricultural and natural resource management in southern Africa and further afield.

Insect Ecology

The Insect Ecology Division focuses on fundamental and applied research on insects and phytophagous mites of importance to sustainable agriculture.

BIOLOGICAL CONTROL of agricultural pests (Cereal Stemborers, diamondback moth, whiteflies & locust) is promoted and actively supported through research on the interactions at three trophic levels, viz. the host plants, pests, and their natural enemies.

The research programme on HONEYBEES aims at the conservation of these ecologically and commercially important insects through the promotion of sustainable beekeeping practices and the study of bee pests and diseases. Our Beekeeping Development Projects ensure that all South Africans have access to the rewarding practice of keeping bees.

PesticideScience.png
Pesticide Science

​The Persticide Science Division is involved with research on the impact of pesticides on the environment, the ecotoxicology and efficacy of pesticides, pesticide residue analysis (Pesticide Analytical Laboratory), the control of pests of stored grain and oil seed (Stored Grain and Oil Seed Unit), the study of the impact of pesticides on the environment, Quelea control, and suitable pesticide application technology (Unit for Pesticide Science).

The Programme consists of: Pesticide Analytical Laborator; Stored Grain and Oil Seed Unit & Unit for Pesticide Science

The Plant Microbiology & Pathology is the Division of the Plant Protection Research (PPR) of Agricultural Research Council (ARC), located in Roodeplaat East of Pretoria providing specialist research and routine diagnostic and advisory services on plant diseases such as soil-borne diseases; seed-borne diseases and foliar diseases using traditional and molecular techniques on fungal, bacterial and viral pathogens with emphasis on those affecting crops to industries, nurseries, commercial and small-scale farmers. (Read more)

The main research focus areas of the Plant Microbiology & Pathology are conducted within the following Units: Virology; Soil Health; Beneficial Nitrogen Fixation; Soil borne Plant Diseases; Fungal and Bacteriology.

Weeds.png
​The Weeds Research Division is responsible for research on the ecology and control of invasive alien plants in South Africa. Our emphasis is on non-native problem plants in conservation and pasture situations, as well as non-native aquatic weeds. Crop weeds do not normally fall within our research field. (Read more)
