ResumoIn early May 1954 some annual aster plants ( Callistephus chinensis ) being grown in sterilized compost in seed boxes were received from a nursery at Mildenhall, Suffolk. Many of these plants were severely stunted and malformed, and some were completely dead. At first sight it looked as if the centres of these plants had been eaten out, but subsequent examination revealed a heavy infestation of chrysanthemum eelworm ( Aphelenchoides ritzema-bosi ), living ectoparasitically among the young leaves. Bunches of nematodes were easily visible in the leaf axils under the low power of a binocular microscope, or even under a good hand lens.
