Abstract: Tablets which include agricultural compounds, and which can be readily dispersed in aqueous media, are disclosed. The tablets include small amounts of microcrystalline cellulose, one or more agricultural compounds which are solid at room temperature, and optionally include additional components such as wetting agents, surfactants, carriers, binders, flow agents, tableting lubricants, antifoam agents, and fillers. The compounds are preferably hydrophobic, such as hydrophobic pesticides. The microcrystalline cellulose has a particle size as close as possible to the initial particle size of the agricultural compound. The particle sizes of the agricultural compound and the microcrystalline cellulose are less than about 100 microns, preferably less than about 50 microns, and more preferably less that about 20 microns, and the particle sizes of both the agricultural compound and the microcrystalline cellulose range from 1:5 to 5:1 more preferably between 1:3 and 3:1, and still more preferably, between 1:2 to 2:1.

Abstract: Tablets for the controlled release of an active ingredient in a zero-order or near zero-order fashion are provided. The tablet includes a core and a coating. The core includes at least one active pharmaceutical agent and a polyethylene oxide with a molecular weight of between about 1,000,000 and 10,000,000, preferably between about 4,000,000 and 8,000,000. The core material is optionally, but preferably, coated with a cellulosic material. The active pharmaceutical agent can be hydrophilic, hydrophobic, or amphiphilic. When the active pharmaceutical agent is a hydrophilic agent, it is preferred that the coating is a relatively hydrophobic cellulose, such as ethylcellulose or propylcellulose. However, if the tablet is uncoated, it can provide a near-zero-order release rate rather than a zero-order release rate.
