Tobacco fumigation with phosphine is the main Industry tool for pest management of infested tobacco and as such, all possible efforts must be made to enforce good fumigation practices to control infestation and minimize the development and spread of phosphine resistance. The CORESTA Sub-Group on Pest and Sanitation Management in Stored Tobacco (PSMST) has investigated and set standards for the implementation of fumigation practices to deal effectively with phosphine resistant beetle and moth populations to curb the spread of phosphine resistance and to keep phosphine as a viable insecticide for the tobacco industry.
