Specialist Pesticide Consultancy

Since my retirement with the Agricultural Research Council (ARC), I have been working as a consultant with several national and international companies for the registration of pesticides. On behalf of the Gundle Plastics Group, one of the largest flexible plastic film manufacturers in South Africa, I prepared dossiers for the registration of their two anti-termite low-density polyethylene (LDPE) membrane products. In 2018, these products were successfully registered with Act 36 (Department of Forestry and Fisheries (DAFF)), for the control of subterranean termites in buildings.
