The Onion ipmPIPE Project is national team of onion experts, growers and industry representatives that created this unique resource to enhance the production, pest management, storage, and marketing of this vital food product for the consuming public in the United States and internationally. This multi-year project is funded in part by the USDA’s Specialty Crop Research Initiative established by the 2008 Farm Bill; and has been endorsed by state and national onion organizations throughout all major onion-producing regions of the country. The project integrates field data input, weather resources, crop planning models, marketing information, image galleries, and wiki pages in relation to onion pathogens, insect pests and crop production.
