Abstract

PURPOSE:To provide a dispersant comprising an alkylene oxide adduct of a polyamine and used for preparing Bordeaux mixtures containing uniform particles having fine particle sizes. CONSTITUTION:A dispersant for Bordeaux mixtures comprises the homo adduct or block or random adduct of one or plural alkylene oxides such as ethylene oxide or propylene oxide to a polyamine such as ethylene diamine, trimethylene diamine, 1, 2, 3-triaminopropane, triethylene tetramine or a polyetylene imine having a mol%. wt. of 500-500000. The Bordeaux mixture containing the above dispersant is excellent in the stability of dispersed particles and has a low viscosity and a stable property, even when the concentration of the particles in the Bordeaux mixture is high. The dispersant is added to the Bordeaux mixture in an amount of preferably 0.1-5wt.% based on the solid content thereof.

Traditionally, this Bordeaux liquid is prepared by separately making an aqueous solution or dispersion of the raw materials copper sulfate and quicklime, and then
For example, this has been done by mixing an aqueous copper sulfate solution with a lime emulsion while stirring in the cold. The mixing ratio of copper sulfate and quicklime varies depending on the purpose of preventing pests and bacteria, but in any case, the dispersion obtained by mixing and reacting as described above is sprayed onto agricultural crops.
