Provided are an additive for a Bordeaux mixture, which additive enables the Bordeaux mixture, to which it has been added, to simultaneously satisfy the following three requirements: excellent dispersion stability both upon preparation and after long-term storage, excellent spreading stability just after spraying and after drying, and excellent visibility of an applied amount just after spraying; and a Bordeaux mixture containing the additive. The present invention relates to an additive for a Bordeaux mixture comprising a polymer having a molecular weight of 5000 to 80000 available by copolymerization, at a molar ratio of 1:1 to 1:9.5, of an unsaturated monocarboxylic acid alkoxypolyalkylene glycol adduct monomer (a) having an HLB of 3.0 to 7.0 and a monomer (b) which is an unsaturated carboxylic acid derivative. |
