ABSTRACT:
Pests are controlled by applying to the location of and/or to the path traversed by the pests a composition comprising urea and sulfuric acid in which the urea/H.sub.2 SO.sub.4 molar ratio is less than 2. Novel compositions useful in such methods are also provided and comprise the described combinations of urea and sulfuric acid dispersed in a hydrocarbon oil. The novel method and compositions are particularly useful for controlling plant pests by applying the useful urea-sulfuric acid components to the plants or to the vicinity of plants occupied or traversed by such pests.
