摘要:
Hatching experiments were carried out with cysts of the potato‐root eelworm. The effect of solutions of potato‐root excretion mixed with root excretions of six types of crucifer seedlings was studied. With cress, white mustard, and black mustard, the emergence of larvae in the mixed excretions was very much less than that from control cysts in potato‐root excretion alone. On subsequent return to potato‐root excretion alone, larval emergence was found to be unimpaired in the case of white and black mustards; in the case of cress, however, the total emergence differed significantly from control. Similar effects, of both types, were obtained with certain dilutions of ally isothiocyanate, the mustard oil of black mustard seed, in potato‐root
