The effect of different pH gradients, mineral salts and fatty acids on the survival of adults and juveniles of Xiphinema americanum Cobb was studied. The optimum pH was 6-6.6. In salts and acids, the adults survived longer than the juveniles, and first stage juveniles survived for the least time. The salts and acids may be arranged in the following order of toxicity: potassium nitrate, copper sulphate, potassium chloride, calcium chloride; formic acid, butyric acid, pripionic acid, a cetic acid.
