Onion ipmPIPE Project

The ONION ipmPIPE was developed in response to stakeholder demands for a coordinated and comprehensive website where onion farmers and agricultural professionals could obtain: 1) real-time information on the distribution and severity of priority diseases and insect pests in North America; 2) time-sensitive disease risk assessments; 3) information on disease and insect pest management options and 4) links to other important tools on onion production and pest management.   Stakeholders are advised of the status of priority diseases and insect pests through observational maps and national/state commentaries on a public website.  This allows all state commentaries/observations within reach in one website.

Emphasis is on  Onion (green, transplanted, seeded, storage, processed); and other alliums such as garlic & chives benefit from research on pests and diseases.  Priority Diseases and Insect Pests include: Iris yellow spot virus (IYSV); Thrips (emphasis on onion thrips) – as a vector of IYSV and a pest;  Other insects such as onion maggot;  Foliar & storage fungal diseases including Botrytis, Purple Blotch, Downy Mildew, Blue Mold, Black Mold; and Foliar & Storage bacterial diseases including Xanthomonas Leaf Blight, Sour Skin, Slippery Skin, Pantoea, Soft Rots.

A national team of onion experts, growers and industry representatives have created a unique on-line resource that will 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.

September 27, 2011 – Most onion crops in the Columbia Basin of WA and OR have been harvested or windrowed. August and September were warm and dry overall. Bulb rots (neck rot, black mold, and bacterial) have been observed in quite a few fields, suggesting this may be a problematic storage season.
