Compositions comprising urea peroxide are effective for treating plants for fungal, bacterial, and viral infections and for infestations of mites and insects. The compositions reduce populations of ice nucleating bacteria on plants, thus protecting the plants from frost damage. The compositions are applied to the aerial portions of plants, e.g., leaves, flowers, fruits, stems, branches, vines, and trunks.
Topical compositions which include urea and carbamide peroxide are described. Compositions having a pH in the acidic range, particularly in the range of about 2.5 to about 9 are also described. Methods for treating dermatological disorders using the composition are also described.
