Onions and Garlic پیاز و سیر


by Heidi Carrubba 2010


Problems and Opportunities

Onions are a major crop in Afghanistan.

  • Priority problems of onions include: scarcity of suitable improved varieties, and IPM for onions and garlic: bacterial soft rot, basal rot, blue mold rot, botrytis leafspot, downy mildew, garlic mosaic, purple blotch and stemphylium leaf blight, rust, white rot, bulb mites, thrips, dodder, and nut sedge. 
  • Priority opportunities include: identifying a short day white or yellow onion that can grow through the winter in the milder/warmer parts of the country to fill an existing market gap, dehydrated onion for international markets (onion powder), and improved irrigation practices.

These draft priority problems and opportunities are based on input from Tom Brown, Alan Walters (SIU), and Donald Harper (USDA).
