National Plant Board

Regional Plant Boards

In 1919, eleven states, the Territory of Hawaii, the Canadian Province of British Columbia and the Mexico District of Lower California met and organized the Western Plant Board for the purpose of discussing and developing uniformity in conducting plant protection work. The Western Plant Board later grew to its current size. The remaining states and the Commonwealth of Puerto Rico were organized into three separate regional plant boards in 1925. The National Plant Board was created the same year.
