Stubby-root nematodes, Paratrichodorus minor, are considered an important pest of onions in Georgia. Low to high population densities of this nematode were observed in multiple fields in the Vidalia area causing damage to sweet onions. The most obvious aboveground symptoms of stubby-root nematode nematode infection are poor, stunted growth of onion seedlings. Stubby-root nematodes have a wide host range, including sugar beets, potatoes, corn, cotton, peanuts, wheat, onions, grasses and some other vegetable crops that are commonly grown in Georgia. Fallow crop rotation with non-host cover crops and treating seedbeds with suitable fumigant and non-fumigant nematicides are effective controls for this pest.
