Florida growers are reluctant to adopt new integrated pest management strategies which include co-use of different fumigants, herbicides, and alternative cultural practices to achieve pest control efficacy and crop yield response similar to that of methyl bromide. Transition to alternatives also requires growers to implement other significant changes to current practices, including integration of new fumigant application technologies and tillage and irrigation practices to enhance performance and to reduce potential fumigant emissions from treated fields. Grower transition to these new IPM methods will be driven incrementally by methyl bromide supply and by many other on-farm, within field, pest, soil, crop, and economic considerations. Transitional strategies which schedule adoption over time and minimize changes to crop production and performance inconsistency of alternatives must be quickly documented for distribution to growers.
