The British root-knot nematode is a significant pest of several cereals, legumes, root and cruciferous crops and is adapted to survive cold and dry conditions. The British root-knot nematode infects and damages cereals such as barley, sorghum, and wheat; crucifer crops such as cabbage, cauliflower, radish, and turnip; and leguminous crops such as alfalfa, broad bean, chickpea, clovers, dogtooth pea, and vetch.
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 British root-knot nematode is most likely to be transported into the United States in infested plant material or infested soil. Infested soil may be associated with some commodities, but the greatest volumes are likely to be moved with international transport of equipment and machinery.
The British root-knot nematode is not known to occur in Indiana.
