Abstract:
A soil adherent pellet is detailed that includes a soluble calcium ion source, a magnesium ion source, or both present in an amount ranging from 15% to 99.9% by weight of a total dry weight of the pellet and a binder present in an amount ranging from 85% to 0.1% by weight of the total dry weight of the pellet. The pellet having a mean pellet domain size and a pellet surface. The soil adherent pellet is well suited for flocculating clay within the soil and delivery of an active ingredient with reduced runoff compared to prior art broadcast particles. A soil adherent pellet is also provided having a soluble calcium and/or magnesium ion source that is polycrystalline and carries therewith an active ingredient.
Abstract:
An inert dispersible granular substrate is suitable for use as a carrier for chemical agents. The granular substrate is comprised of one or more mineral components, the one or more mineral components having a bulk density of greater than about 70 pounds per cubic foot, one or more dispersibility additives; and one or more water soluble binders. The granular substrate has a bulk density of from greater than 55 pounds pcf to about 70 pcf, a water dispersibility of less than 5 minutes, a pH of from 6 to 8, and sufficient strength to survive formulation processing after 3 days of continuous exposure to a temperature of approximately 75° F. and a relative humidity of approximately 95%. Preferably, an active pesticide is applied to the dispersible granular substrate. The water dispersible granular substrates may be produced by forming a granular substrate admixture, pelletizing the admixture to form granular substrates, and drying the granular substrates.
Abstract:
A pesticide granule is provided that includes a base carrier particle. A liquid pesticide coating is applied to the particle surface. The coating may contain adjuvants. The coating has sufficient tack to adhere a second powdered pesticide to the carrier particle. The usage of tackifying agents to render the particle surface tacky enough to adhere powdered pesticide is reduced or eliminated. The powdered pesticide is sized to a mean diameter of less than 10% of the carrier diameter to promote adhesion. The synergistic rapid acting pesticide delivery associated with the granule results in the usage of less pesticide to control a given pest with reduced environmental impact. Bifenthrin is a representative of the liquid pesticide.
Abstract:
A composition is provided that includes in combination fertilizer particles inclusive of a plant nutrient component and a binder inhibitive of particle disintegration. The fertilizer particles are mixed with and dispersed in concert with bait particles attractive to a pest and inclusive of a pesticide or pest reproduction control agent. The bait particles remain sufficiently devoid of adherent fertilizer particle fragments so as to remain attractive to a target pest. Composition homogeneity is maintained by density matching between the fertilizer particles and bait particles or compensating for differences in density by sizing the lower density particles larger than the higher density particles.
Abstract:
A water-dispersible particle for delivery of fertilizer to a plant is disclosed. After delivery wetting of the particles causes particle dispersion so as to prevent secondary pick up to the particles. Methods for making and using the water-dispersible particle are described.
Abstract:
A manufactured granular substrate composition suitable for use as a carrier for active chemical agents. The composition includes about 65 wt % or more of one or more mineral components having a bulk density greater than about 70 pounds per cubic foot. The composition also contains about 5 wt % to about 25 wt % of one or more light weight additives and up to 20 wt % of one or more water soluble binders. The resulting manufactured granular substrate is readily dispersable in water and has a bulk density of less than about 55 pounds per cubic foot with a size guide number of about 100 to about 230.
Abstract:
A vegetation culture active agent delivery medium is provided that includes dense mineral granules, comparatively less dense cellulosic granules, and an active agent in simultaneous contact with the mineral granules and the cellulosic granules, the active agent present from 1×10−5 to 10 total weight percent of the medium. A formulation of an active agent is applied to one type of granule as a mixture thereof. Through control of the relative amounts of mineral and cellulosic granules, a controlled medium density is readily adjusted between 35 and 60 pounds per cubic foot.
Abstract:
A weed control particle is provided that includes a delivery granule having a surface and a core. A dicarboximide herbicide is adhered to the surface, mixed into the core of the granule, or both. A dinitroaniline herbicide is adhered to the surface, mixed into the core of the granule, or both. A process of weed control includes distributing such particles or two separate types of particles that each have one of the two types of herbicides to a plot around a desired plant. The weed control particles are distributed at a density such that said dicarboximide herbicide is present at between 20% and 80% of full rate for the dicarboximide herbicide and the dinitroaniline is present at between 20% and 70% of full rate for the dinitroaniline herbicide to provide weed control around the desired plant.

A water-dispersible particle for delivery of fertilizer to a plant is disclosed. After delivery wetting of the particles causes particle dispersion so as to prevent secondary pick up to the particles. Methods for making and using the water-dispersible particle are described.
Abstract:
A water-dispersible particle is provided that includes organic origin potash in an amount ranging from 5% to 99.9% by weight of the total dry weight of the particle. A binder component is present in an amount from 1% to 95% by weight. The organic origin potash and the binder component on that contact with water causes particle dispersion into more than 100 pieces.A process for making a water-dispersible particle includes mechanical aggregation of the potash into a pellet. A binder component is present in the particle in an amount ranging from 1% to 95% by weight. The potash and the binder component are present in a form such that contact with water causes particle dispersion into more than 100 pieces. The pellet is then dried and ready to be applied.
