Biological-Based Crop Protection aims to develop sustainable, biologically-based, crop management technologies that utilise naturally-occurring pathogens and phytotoxins to control economically important insect and nematode pests. The team provides policy and registration guidance to Governments and other stakeholders through consultancies, and builds capacity through training and knowledge management. The team advocates sustainable technology transfer to both public and private sectors in support of resource-poor farming communities.

Achievements

Achievements include: new NPV formulation validated for control of African armyworm, and mass-production techniques developed; registration guidelines on microbial biopesticides and biochemical pesticides developed for the Ghanaian Environmental Protection Agency; isolation and identification of novel pathogens for control of African maize stem borers; and assessment of efficacy of combinations of antagonistic fungus, rhizobacteria and marigold to improve control of root-knot nematode in an integrated crop management strategy for tomato in South Asia. Novel evidence relevant to biopesticide usage has shown that Bacillus thuringiensis can have a dynamic, vegetative existence on the phylloplane which includes genetic transfer.

Future Plans

Our strategy is to continue to provide donors, government agencies and SMEs with high-quality research-informed technical and policy support for commercial exploitation of biological-control products for crop pest management; develop international partnerships in research to improve methodologies for production, formulation and application of biological-control agents, so that small producers can access the technology for local production and application; and develop biorational techniques as component technologies in novel integrated crop management strategies to meet the needs of resource-poor farming communities. These actions will build on initiatives developed through projects on chickpea, tomato and brassicas in South Asia, and maize and vegetables in Africa.
