The Relationship Between Root-Knot Nematode and Growth of Cotton

T.A. Wheeler, K. Hake, K. Stair, H. W. Kaufman


One hundred fields were sampled for nematodes and plant mapped in 1995. The proportion of fields infested with root-knot nematode in the Southern High Plains was 60% or higher in seven of the 20 counties surveyed and more than 1.4 million acres of cotton is grown in these seven counties. Root-knot nematode was found in 39% of all fields sampled and 18% of those fields had an average root-knot nematode population > 500/500 cm3 soil (16% were greater than 1000 root-knot nematode/500 cm3 soil). Root-knot nematode density was associated with a reduction in the nodes above white flower and number of squares in irrigated but not dryland fields.
