Zusammenfassung:NEW MATERIAL:A compound of formulaI{R is 10-17C alkyl, 2-21C alkylene or formula II or III[X is H, halogen, OH, lower alkyl or alkoxycarbonyl having 1-12C in the alkyl group; (n) is an integer 1-3; Y and Z are H, halogen, lower alkyl or phenyl]}. EXAMPLE:Tricyclohexyltin laurate. USE:An agricultural and horticultural acaricide, capable of exhibiting improved killing activity against imagoes, eggs and larvae of Panonychus citri, Panonychus ulmi, Tetranuchus kanzawai, etc. PROCESS:A compound of formula IV (R is chlorine or OH), e.g. tricyclohexyltin hydroxide, is reacted with a compound of formula V (R is H or alkali metal), e.g. lauric acid, in a solvent, e.g. benzene, at 40-60 deg.C for 2-3hr.
