| 摘要 |
A storage stable, water emulsifiable, substantially non-aqueous liquid or low melting solid concentrate adapted for on-site preparation of an aqueous emulsion of an agricultural chemical, consisting essentially of a solution, in (a) a liquid hydrophobic agricultural chemical having biocidal activity, of (b) a solid hydrophobic polymer, in an amount effective to achieve sustained release of (a), and (c) an emulsifying agent, in an amount effective to form a stable oil-in-water emulsion when the concentrate is mixed with water.
