The Nursery Stock Grower and Dealer Inspection Program assures that the nursery stock sold in Iowa is free of injurious insects and diseases of regulatory concern, which might adversely effect the growth of the stock or which might be further infest the state. Inspectors of the Entomology and Plant Sciences Bureau annually inspect all nursery stock grower operations, and only stock meeting the inspection criteria are certified for sale. While at nursery stock grower operations the personnel advise growers concerning the prevention of regulatory and non-regulatory insects and diseases. This latter function is a service to the nursery industry of Iowa. Once stock passes the inspection, the nursery stock can be sold in Iowa as well as other states with parallel regulations.
