〔産業上の利用分野〕
本発明は粒子径の細かい均一な粒子を含有するボルドー
液を得るための分散剤に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a dispersant for obtaining a Bordeaux liquor containing uniform particles with a fine particle size.
ボルドー液は、リンゴ、ナシ、ブドウをはしめ様々な農
作物の防害虫、防菌用農薬として、長年にわたって伝統
的に使用されてきた。Bordeaux liquid has been traditionally used for many years as a pest and fungicidal pesticide on a variety of agricultural crops, including apples, pears, and grapes.
ボルドー液は、安価であるばかりでなく、近年とみに問
題となっている蓄積性の有機塩素系農薬を避ける傾向か
らも、すたれることなく、却ってその使用量が漸増して
いる。Bordeaux liquid is not only cheap, but also because there is a trend to avoid accumulating organic chlorine pesticides, which have become a problem in recent years.
このボルドー液の調製は、従来より、原料となる硫酸銅
と生石灰とを別々に水溶液または水分散液としたのち、
たとえば冷時撹拌しながら石灰乳液に硫酸銅水溶液を混
合することにより、行われてきた。硫酸銅と生石灰との
混合比率は、防害虫や防菌の目的により異なるが、いず
れにしても上記のように混合し反応させて得た分散体を
、スプレーによって農作物に散布している。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.
このようなボルドー液の調製や散布法に関する技術とし
ては、たとえば特開昭５１−４４６２９号公報、同５２
−３８３７１号公報などにその記載がみられ、また長期
間安定なボルドー液を得るために、たとえば特開昭５３
−５２６２２号公報にはりゲニンスルホン酸塩などの保
護コロイド剤を用いることが開示されている。Techniques related to the preparation and spraying of Bordeaux liquid include, for example, Japanese Patent Application Laid-Open Nos. 51-44629 and 52
The description can be found in Japanese Patent Laid-Open No. 38371, etc., and in order to obtain Bordeaux liquid that is stable for a long period of time, for example,
JP-A-52622 discloses the use of a protective colloid agent such as genin sulfonate.
しかるに、ボルドー液は、石灰乳液のつくり方やこの乳
液と硫酸銅水溶液との混合の仕方などで、品質、安定性
などが大きく影響され、上記公知の技術で粒子径の細か
い均一な粒子を含有するボルドー液を得るのは容易では
なく、かなりの熟練が要求される。However, the quality and stability of Bordeaux liquor are greatly affected by the way the lime emulsion is made and the way this emulsion is mixed with the aqueous copper sulfate solution. Obtaining Bordeaux liquid is not easy and requires considerable skill.
粒子径が大きくなると、散布したときの農作物への展着
性が悪く雨などが降った場合に簡単に流れ落ちたり、噴
霧液の容器内で沈降してノズルが詰まったり濃度がばら
ついたりして均一な散布ができないといった問題を生し
る。If the particle size becomes large, it will not spread easily on crops when sprayed, and it will easily wash off when it rains, or it will settle in the spray liquid container, clogging the nozzle, and causing uneven concentration. This results in problems such as not being able to spray properly.
