Insect Management for Onions, Leek, and Garlic

Sweet varieties of bulbing onions, which make bulbs under short day conditions and do not store well, are by far the most common onions grown in Florida. They are generally grown on small acreages in the winter for local and farmers markets. In Hillsborough County and in the Suwannee Valley, strawberry growers are the major producers of onions, many of which are harvested green. This 2-page fact sheet written by Xavier Martini and Susan Webb and published by the UF/IFAS Entomology and Nematology Department reviews the management of the two major onion pests in Florida: thrips and seedcorn maggot. https://edis.ifas.ufl.edu/ig153 Previous versions: Webb, Susan. 2002. “Insect Management for Onions, Leek, and Garlic”.
