Pesticide formulations,ct pests, destroyers of nonmetallic materials, and undesirable plants. The different natures of the chemical compounds used and the variety of objects for which they are used makes it necessary to produce a large number of formulations suitable for employment under practical conditions.

Alcohols, phenols, and ethers,th increasing molecular weight, but after reaching a certain size it decreases. Thus, the maximum for fungicidal activity is reached at undecyl and dodecyl alcohols. The sprouting of potatoes is most effectively inhibited by nonyl and decyl alcohols.

Derivatives of urea and thiourea,ntrol of weeds in crops of cotton, corn, and others. In spite of the large dosages, biuret may have practical importance, since in the soil it undergoes hydrolysis with the formation of ammonia, which is utilized by crop plants as a source of nourishment.

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.
