  • Welcome to the Plant Program Area at ODA!

    The Plant Program Area includes four sections: Insect Pest Prevention & Management, Native Plant Conservation, Noxious Weed Control, and Nursery & Christmas Tree. The programs protect Oregon's agricultural industries and natural environment from harmful plant pests, diseases and noxious weeds; enhance the value and marketability of exported nursery stock, Christmas trees, seeds and other agricultural products; and further the conservation of threatened and endangered plants.

Exceptions include businesses whose total sales do not exceed $250 per fiscal year and/or landscaping businesses or brokers that do not grow or store live plant material for more than one year.
