Clean Plants Program offer a number of benefits to the tree industry, primarily in providing disease free plant material to the industry and allowing nurseries to sell plants under the CNCP for export of their plants to the US to meet USDA requirements. When nurseries obtain certification through CNCP and the Clean Plants Program, it is their objective to produce plants that meet high phytosanitary standards and plants that are completely free of all regulated pests and substantially free from all other insects and diseases.
The Clean Plants program, originally called the Domestic Phytosanitary Certification Program (DPCP), was developed in 2006 by a team of experts operating under Canadian Nursery and Landscape Association (CNLA) supervision.
