LIQUID BIOCIDAL FORMULATION, A PROCESS FOR PREPARING SUCH FORMULATION, AND THE USE OF SUCH FORMULATION

摘要

Water dispersible liquid concentrates of acaricidal organotin compounds, comprising 2.5 to 50% w/v at least one emulsifier, at least one saturated or unsaturated mono- or di-hydric alcohol optionally substituted by one or more alkoxy, alkoxyalkoxy, alkoxycarbonyl, alkylcarbonyl, alkylcarbonyloxy, or aryl groups present in an amount up to 80% w/v and, dissolved therein, from 10% to 50% w/v of a tricyclohexyl tin or trineophyl tin derivative, may be prepared by heating the organotin compound in the presence of at least part of the alcohol to at least 50.degree.C. The concentrate formulations may additionally contain a non-alcoholic waterimmiscible organic liquid, and up to 10% w/v of a carboxylic acid. The concentrates disperse readily in water.
