Filed:

Jul 11, 2002

Appl. No.:

10/194724

Inventors:

David T. Schulteis - Fresno CA

Assignee:

Wilbur-Ellis Company - San Francisco CA

International Classification:

A01N 3312

US Classification:

504121, 504118, 504120, 504123, 504148

Abstract:

A composition for regulating the growth of plants in which an effective amount of chlorocholine chloride, poly[oxyethylene(dimethyliminio)ethylene(dimethyliminio)ethylene]dichloride, and choline chloride, is diluted in an inert carrier. The inert carrier may be water, a solvent, or a surfactant. The composition with the diluent forms a liquid solution, which is sprayed on the foliage of subject plants prior to harvest. At least one inorganic salt may be added to the composition to enhance the efficacy of the liquid solution. A first formulation of the solution, preferably including the inorganic salt additive, may be applied early in the plants development to discourage rank growth without inducing Cut-Out. A second formulation of the solution, having no inorganic salt but including a greater amount of chlorocholine chloride, may be applied late in the plants development, to induce Cut-Out.

International Classification:

US Classification:

424408, 424417, 504140, 504271, 514380

Abstract:

Water-dispersible, extruded granules for delivering agricultural chemicals, such as pesticides or non-pesticidal materials, to a crop. The granules are extrusion-formed from a blended composition including at least one active chemical ingredient, a solid carrier, and a binder. The active chemical ingredient may or may not be micro-encapsulated. The binder may be added directly to the composition or applied as a coating to the granules after the extrusion process. The binder reduces attrition, chemical volatility, and phytotoxicity. The granules are applied to a crop field by aerial means. The dense granules display good vertical drop characteristics, with little drift. If the crop field has standing water, the water-dispersible granules sink and break up, effecting dispersion of the chemical ingredient. When applied to a dry field, the subsequent exposure to water to the granules effects the same dispersal of chemical ingredient.

US Classification:

424 942

Abstract:

An insecticidal composition and its method of preparation are presented. The composition comprises a basal broth, a chitinase broth and a chemical fungicide. The basal broth has proteins hydrolyzed by papain and pancreatin while the chitinase broth is prepared by fermenting chitin and a chitinase-producing bacterial culture. The insecticidal composition has synergistic activity.
