C. E. Berkoff,R. D. Cramer III,G. Redltivity is increased when nitro, amino, and hydroxy groups are introduced, but in the first and second cases the toxicity to mammals also is increased. The aliphatic esters of salicyclic, anthranilic, and anisic acids are moderately toxic to body lice and codling moths.
