Summary: In 2019, nematodes (root-knot and reniform) caused the most significant cotton disease problems in the Southern High Plains. Advanced cotton-breeding lines and varieties with two-gene resistance had much lower densities of root-knot nematode in a field trial than root-knot-susceptible varieties. Breeding lines with reniform nematode resistance from Phytogen had less reniform reproduction than most commercial varieties in a field trial. These reniform-resistant lines also grew much larger than commercial cotton varieties in a reniform field. There was little Verticillium wilt and bacterial blight in 2019, although differences in variety susceptibility to these diseases are presented.
