Fertilizer/Pesticide Composition And Method Of Treating Plants
US Patent:
5174804, Dec 29, 1992
Filed:
Sep 29, 1989
Appl. No.:
7/415162
Inventors:
Bobby E. Rehberg - Winter Haven FL
William L. Hall - Lakeland FL
William L. Hall - Lakeland FL
Assignee:
Vigoro Industries, Inc. - Fairview Heights IL
International Classification:
C05G 900, A01N 2508
US Classification:
71 3
Abstract:
Fertilizer/pesticide compositions are disclosed which include a fertilizer component and an active component. The fertilizer component includes plant nutrients, and the active component includes an active material, such as a pesticide, which has a desired effect on plant growth or health when released to the plant over an extended period of time. In a preferred form, the fertilizer component is admixed with the active component and a binder and compressed to form a briquette in which the fertilizer component occludes the active component. The briquette is essentially free of significant quantities of materials which have a high solubility in water. Thus, when a briquette is placed in the soil, it releases nutrients and the active material into the soil over an extended period of time for delivery to the plant. A method of treating plants with such fertilizer/pesticide compositions is also disclosed.
Fertilizer Compositions And Method Of Making Such Compositions
US Patent:
5238480, Aug 24, 1993
Filed:
Jun 29, 1989
Appl. No.:
7/374109
Inventors:
Bobby E. Rehberg - Winter Haven FL
William L. Hall - Lakeland FL
William L. Hall - Lakeland FL
Assignee:
Vigoro Industries, Inc. - Fairview Heights IL
International Classification:
C05C 900, C05G 310
US Classification:
71 28
Abstract:
An improved fertilizer composition is disclosed, including particles of a sparingly soluble fertilizer source having porous outer surfaces (for example, IBDU. RTM. ) which have been coated with a hard outer coating that substantially covers the surface of each of the particles and substantially fills the pores in the surface of each of the particles. The particles are thereby hardened by the coating and are given increased resistance to abrasion and dust formation. The hardened outer coating is preferably formed when a liquid binder (which preferably includes a mixture of urea and a lignosulfonate) is sprayed onto the particles and then allowed to harden or cure. A process for making such hardened fertilizer particles is also disclosed.
