Plant Import Information

Prohitited genera

Germplasm of prohibited genera may not legally enter the United States except through approved quarantine facilities and testing procedures. This is because uncontrolled importation of such germplasm would pose an unacceptable risk of unintentional importation of serious diseases, insect pests, or weed species. Relevant laws include The Plant Quarantine Act of 1912 (as amended), The Organic Act of 1944 (as amended), The Federal Plant Pest Act of 1957 (as amended) and the Federal Noxious Weed Act of 1974 (as amended). Regulations promulgated under these laws are found in the Code of Federal Regulations, in particular at CFR 319 subpart 37 "Nursery stock, plants, roots, bulbs, seeds and other plant products".

Crops that are assigned to the PGQP for processing include pome and stone fruit trees, sweet and white potatoes, sugarcane, rice, small soft fruits except strawberry and grape, ornamental and turf grasses, and many shade trees and other species used for ornamental and landscape purposes. For many of these crops the PGQP is the only legal means of entry. In the case of pome and stone fruits a separate, fee for service-based program is available through the NRSP-5 at Prosser, Washington.
