The status of the debate on managing methyl bromide emissions and on their role in depletion of stratospheric ozone is outlined. Some of the agendas and targets are discussed in the context of handling postharvest grains in both developed and developing countries in Asia. Current needs for methyl bromide fumigation are identified and applications in disinfestation of grains positioned in the global pattern of usage. Areas are explored where alternative technologies are required, and the attributes defined that should be inherent in these replacement technologies, if they are to be viable in the demanding areas of quarantine and commodity sale contracts and the increasing sensitivity to any chemical additives, especially pesticides, in foodstuffs or the environment. The technologies that would complement, supplement or replace fumigation with methyl bromide and so enable chemical control to be properly placed in appropriate pest management strategies are then outlined. Finally, the principal chemicals that are candidates for chemical-based alternative technologies are discussed in terms of their characteristics, advantages, disadvantages and the constraints that are attendant on their use. The materials include both old and new fumigants and contact pesticides, and 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.
