Description of Activities

Biopesticides are pest control products derived from animals, plants, bacteria, and certain minerals. While a significant number of biopesticides have been developed over the years, their use remains relatively limited. This is attributable to several factors, including: i) concerns regarding potential risks associated with their application; ii) regulatory hurdles due to, inter alia, over-reliance on chemical pesticide approval regimes which are not sufficiently evolved to effectively regulate biopesticides; iii) a paucity of information relevant for their evaluation, registration and commercial release, and; iv) technical constraints relating to viability, cost, scale of production and bioefficacy. The Biopesticides Group supports the discovery, development, formulation, commercialisation and use of biopesticides. This is achieved through a programmatic approach, which involves strategic engagement with relevant stakeholders to address the challenges confronting research, development and adoption of biopesticides. Given its approach, the Group does not host PhD fellows. It, however, supports postdoctoral fellowships focussing mainly on policy and regulatory aspects of relevance to biopesticide research and development.
