IR-4 Program

The Interregional Research Project No. 4, commonly known as IR-4, is a federally funded program that helps growers of ornamental horticulture crops find safe and effective pest management tools. The IR-4 Program is a unique partnership between the USDA and land grant universities, such as OSU.

The IR-4 Program at NWREC conducts efficacy and crop safety trials on ornamental and specialty crops that are important to Oregon growers.The main focus of the IR-4 Program is to generate crop safety information and add new crops to pesticide labels (any pest control product, be it conventional, biological or organic, must be registered and labeled).
