Documented Uses

• Used as an acaricide for control of a wide variety of mites on citrus and deciduous fruit; Not currently registered with the EPA for use in the US; [HSDB]
• Controls a wide variety of mites on citrus and deciduous fruit.
• Bromopropylate is produced by esterification of 4,4'-dibromobenzilic acid with 2-propanol.
• Preparation FR 1504969; K Gubler, US 3639446 (1967, 1972 to Geigy).
• It was introduced in 1966 by JR Geigy SA (now Ciba-Geigy AG) as exptl acaricide under code number 'gs 19851', trade marks 'Neoron' & 'Acarol' & protection of Belgian patent 691105; Swiss patent 471065. It was described by H Grob et al, Abstr Int Plant Prot Congr, 6th, 1967, page 198.
