บทคัดย่อ

The debate on managing methyl bromide emissions and their role in stratospheric ozone depletion is outlined. Some of the agendas and targets are discussed in the context of handling post-harvest grains in both developed and developing countries in Asia. Current needs for methyl bromide fumigation and global usage patterns are identified. Areas are explored where alternative technologies are required, and the necessary attributes of these alternatives are defined. The technologies that would complement, supplement or replace methyl bromide fumigation include residual pesticides, inert dusts, high temperature disinfestation, pheromone trapping, irradiation and alternative fumigants. The principal chemical alternatives, including carbon dioxide, phosphine, carbon disulfide, carbonyl sulfide and ethyl formate, are discussed. These materials are considered within the context of designing optimum strategies using modern management tools, such as integrated pest management supported by risk assessment

and precision targeting of treatments, together with other decision-support systems.
