Abstract
groundnuts have generally been considered to be resistant to root-knot nematodes but Machmer shows that there are two species of the genus Meloidogyne (root-knot nematode) in the south eastern United States which seriously damage groundnuts grown in that region. These are Meloidogyne hapla from Pitt County, North Carolina and M. arenaria from south-west Georgia in which State groundnuts are extensively affected in the lower Chattahoochee River basin. The eelworm causes serious injury and galling to the underground parts of the plant including pods and pod stems and crops of groundnuts may be so severely damaged as to be not worth harvesting. Two species of senna or coffee weed, viz. Cassia occidentalis and C, tora are also severely galled in the roots by M. arenaria, and Indigofera hirsuta, used as a rotational crop, also becomes seriously galled. Crotalaria spp. and Desmodium sp. (beggar weed) being immune, can be used as rotational crops and help to reduce infestation. T.G.
