Abstract: A synergistic agricultural formula including at least one diacyl or diaryl urea, such as a N,N?-diformylurea, and at least one plant growth regulator. This synergistic agricultural formula gives those skilled in the art the ability to regulate important phenotypical parameters that lead to a variety of important agronomic and horticulture traits which improve crop yield parameters leading beyond that of its individual components.

Abstract: The present invention is directed to a method of inhibiting the growth of disease organisms on and in plants by directly applying an aqueous solution comprising urea and at least one water-soluble salt of a divalent cation and a monovalent anion to the seeds, stems, bark, leaves, seed heads or sub-surface root zones of said plants. The weight percent ratio of urea to divalent cation in these solutions should be from about 0.25-10.0 to 1.0. Preferred divalent cations include those of the alkaline earth metals and the transition metals. Most preferred are calcium, magnesium, zinc, manganese, copper, iron, cobalt, nickel and mixtures thereof. Preferred anions include nitrate, chloride, bromide and mixtures thereof. In more preferred solutions, the ratio of urea to divalent cation is from about 2.0-7.0 to 1.0. Particularly preferred solutions include calcium chloride as the water-soluble salt. Optionally, a second water-soluble salt of a divalent cation and a monovalent anion may be included.
