The processing tomato industry >n the Azua Valley of Ihc Dominican Republic, represents the main source of incomes for more than 3,000 small farmers and Uic principal activity For 4 tomato industries established in die region. The tomato industry was almost devastated as the result of (he presence of the White Fly and the geminivirus (TYLCV) infestations. To recover the productivity of the tomato crop, it was necessary to implement and validate a scries of integrated pest management practices. Correct planting time, use of resistant and early varieties, and application of legal measures, arc among these practices. Combined widi these, the production of tomato plantlets under mosquito net tunnels, reduces the early infection of TYLCV. This reduction results in an increase of yield and greater incomes to farmers. This paper describes a viable and economic method of producing planting materials using locally available resources.
