Abstract
Root-knot nematodes, Meloidogyneincognita and M. javanica readily attacked Celosia argentea, significantly reducing its early, rapid growth.
At harvest, 74 days after emergence, all plants grown in root-knot-infested soil were significantly smaller and lighter than plants grown in fumigated soil.
Roots of the attacked plants were heavily galled, indicating that this cultivar of C. argentea was highly susceptible to root-knot nematodes.
As an economic crop it is suggested that C. argentea needs to be grown in a rotation regime in which the plant parasitic nematode populations are kept below damage-inflicting thresholds.
