False Columbia Root-Knot Nematode

Meloidogyne fallax (Karssen)
False Columbia  Root-Knot Nematode False Columbia  Root-Knot Nematode

 

Hosts:

Primary hosts for this species include potato, oyster plant, and carrot, as well as the perennials primrose, bleeding heart, and daylily. Secondary hosts include tomato, lettuce, and artichoke.

 

Commodities Affected:
Field Crops, Fruits and Vegetables

 

Threat:

Meloidogyne species are among some of the most economically important plant parasitic nematodes found worldwide. Crop loss resulting from nematode damage to vegetables and grains has been estimated at an average of 10-11% worldwide, but the economic impact from nematodes is thought to be grossly underestimated.

The false-Columbian root-knot nematode can be spread via movement of infected or contaminated planting material, such as daylily bulbs or seed potato tubers. In addition, the movement of non-host seedling transplants, nursery stock, machinery or other products which are contaminated with the false-Columbian root-knot nematode infested soil have the potential to spread this pest.

 

Distribution:

The false-Columbian root-knot nematode is n ot known to occur in Indiana.
