1. The composition of agricultural chemicals includes a solvent, whose general formula is co (ORA) (RB),Among them, RA is a group of linear tar or branch, composed of one to eight carbon atoms and Rb, which is an aromatic group. The active ingredients used in agriculture are dissolved in solvents to produce a solution that can be used to distribute the active ingredients. These include: about 5% to 70% of agricultural chemicals by weight, including one or more compounds in the group to be composed of pyrethroids, mythical inhibitors, protogen IX oxidase inhibitors,Herbicide, bleaching agent, trimer, methyl ether compound, photosynthesis inhibitor, insecticide, promoter / antagonist of nicotine receptor, fungicide, strontium, anthrax, ALS inhibitor, plant development supervisor, soft bactericide, nematicide, About 30% to 80% of fungicides and their mixtures, as well as some esters containing one or more compounds, are generally formulated as CO (or) (RB),The characteristic is that RA is a linear tar or dendrite group consisting of one to eight carbon atoms and Rb is an aromatic group. 11. Claim 3: production of chemical substances for agricultural production in accordance with claim 1, characterized by RA being selected from a group of substances consisting of methyl, ethyl, propyl, butyl, pentachlorobenzene, hexilo, heptyl, octabromo and their derivatives. 11. Claim 4: produce chemicals for agriculture in accordance with claim 1, characterized by RB being selected from the group of bencilo, xililo, tolulio and their derivatives.Una composición de sustancias químicas para la agricultura comprende un solvente que tiene la fórmula general CO(ORa)(Rb), en el cual Ra es un grupo alquilo lineal o ramificado de entre uno y ocho átomos de carbono y Rb es un grupo aromático. Los componentes activos para la agricultura se disuelven en el solvente para producir una solución que se puede utilizar para distribuir los componentes activos.Reivindicación 1: Una formulación de sus
