ADDITIONAL INDEX WORDS. Canada, emerging pests and diseases, exports, floriculture, imports, ornamental plants SUMMARY. The purpose of this study was to evaluate the U.S.-Canadian Greenhouse Certification Program (USGCP) that was initiated in 1998. A survey consisting of 34 questions was designed and 43 out of 48 nurseries in Florida participating in the USGCP were visited. Based on the answers to the questionnaire, most of the nurseries were in compliance with the majority of USGCP requirements, growers were satisfied with the program, and there was an economic benefit to participating in the program. The main problems identified were theambiguous wording of some of the requirements and the impracticality of keeping imported and domestic plants completely segregated. Moreover, many of the respondents did not have a written description of a pest management plan. Chi square statistical analysis showed that there was almost no difference between nursery groups in their responses to the majority of the survey questions, indicating that the USGCP is a successful program forbothlarge andsmallnurseries.Thisquantitativeassessment oftheUSGCP isthe first assessment conducted for this program and discussed in a peer-reviewed publication.
