The reniform nematode (Rotylenchulus reniformis) has been identified in the eleven states that make up the southeast cotton belt. This includes all cotton producing states extending from Texas to North Carolina. In this region more than 11.7 million areas of cotton are produced annually. Texas alone produces more than 5.5 million acres of cotton leaving 6.2 million acres of production in the remaining ten states. Excluding Texas, it has been estimated that 1.2 million or 19% of the remaining acres are infested with the reniform nematode. The highest infestations occur in Georgia, Louisiana, and Mississippi in which this nematode has been identified in 29.6, 55.0, and 32.4 percent of the cotton acreage, respectively. In Texas only 2.7% of the 5.5 million acres are infested. The majority of reniform nematodes occur in the lower Rio Grande Valley, Brazos River Valley and Upper Gulf Coast counties.
