Implementation of a Microbial Pest Control Product in an Integrated Pest Management Programme

Abstract

Key factors to cost-effective implementation of a microbial pest control product are application strategy, compatibility, and knowledge transfer to the user. This requires the design of a comprehensive integrated pest management programme in which the microbial pest control product is to be incorporated. The first element is an optimal application strategy per targeted pest and cropping system. Determinative parameters such as dosage and spray volume are discussed as well as factors that influence these parameters such as the tritrophic plant-host-pathogen relationship. The second element is the incorporation of the microbial pest control product in an IPM system. Compatibility with chemical pesticides and with beneficial organisms must be established and critical aspects are mentioned for each type of pathogen. Microbial pest control products and natural enemies are often simultaneously used in IPM systems to enhance control. Synergistic, additive and negative interactions are reviewed. Combinations of microbial pest control products and combinations with other means are discussed. The risk of resistance will be briefly treated. The third element is the implementation of a microbial pest control product into practice. Adoption of new products needs knowledge transfer in the entire supply chain to the grower, and pivotal considerations including economic aspects will be reviewed. Requirements and recommendations will be provided on how to accomplish a successful implementation. Considerations will be presented with regard to the compatibility profile, the advantages and the disadvantages of biopesticides, the cost of the implementation process, and to the potential of combined use of biopesticides.
