The toxicity of organic sulphides to the eggs and larvae of the glasshouse red spider mite. III.—benzyl phenyl sulphides substituted only by halogens

Abstract The activities against the eggs and young mites of the glasshouse red spider (Tetranychus telarius L.) have been determined for a series of benzyl phenyl sulphides containing only halogen nuclear substituents. The results, together with the results from some of the corresponding sulphoxides and sulphones, are tabulated and discussed.
