Abstract: A micro-encapsulated pepper-mustard composition which comprises positioning pepper and mustard mixtures within a cluster of surfactant molecules, i.e. micelles, dispersed in water. This micro-encapsulation process involves first forming the micelles in water by exceeding the given critical micelle concentration for either one, two, or three different surfactant types. The active ingredient, pepper and mustard, is then added to this mixture and subsequently emulsified into small liquid drops in order to facilitate swelling of the micelles by way of migration or diffusion of the active ingredient molecules through the water phase and into the micelles. The resulting encapsulated pepper and mustard is effectively stabilized by the surfactant molecules, and the resulting stabilized micro-encapsulated dispersion will not undergo phase separation.

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.

Abstract: Microcapsules formed from an aminoplast shell wall and an encapsulated ingredient or ingredients enclosed within the wall in which the wall contains a base-cleavable ester moiety. These capsules have been found to be sensitive to the presence of base such that in the presence of base, the capsule walls are relatively quickly disintegrated or degraded so as to produce a relatively quick release of the encapsulated materials. Microcapsules of this invention are particularly suitable for use in controlling insects having an alkaline gut such as certain lepidoptera in that the capsule shell wall may be designed so as to quickly disintegrate under the alkaline conditions present in the gut of the insect thus providing a microcapsule which is safe to handle but which is selectively effective against certain undesirable insects while not harmful to beneficial insects or insects which do not feed on the capsule materials.
