Zusammenfassung: | 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. Using the technology described herein, the tablets can include up to 70 percent by weight of the agricultural compound. In some embodiments, a blend of particle sizes for the microcrystalline cellulose, for example, a blend of relatively large and relatively small MCC particles is used. This embodiment tends to produce a mix that flows better in a tablet press and reduces the cost of production. |
