Dissipation study of amitraz acaricide was conducted in two cattle dips in Bureti, Kericho County. Farmers in the region experience frequent reoccurrence of ticks resulting into huge management losses due to tick borne diseases. Whereas amitraz is widely used for ticks control, little success has been achieved against management of ticks in Bureti. The objective of this study was to establish whether the application rates used in the dips met the recommended guidelines, and whether dissipation affected efficacy of the pesticide in the dip solutions. We collected cattle dip solutions after 30 minutes of application, then 3, 24, 48, 72, 96, 120 and 144 hours. We extracted amitraz from aqueous solution following liquid-liquid extraction technique using dichloromethane. Amitraz content in the samples was analysed by Gas Chromatograph equipped with Mass Selective Detector, GC-MS. Both dip solutions contained amitraz levels below the recommended dosing rate 1.49 ± 0.11 mg/L and 1.46 ± 0.28 mg/L on day 0 in dips 1 and 2 respectively. The half-life of amitraz was found to be 17 and 18 hours for dips 1 and 2 respectively. The fast dissipation rate of amitraz in the dips contributed to fast declining levels of the pesticide residues in the dip solutions leading to poor control of ticks. The results suggest the need to replenish the dip solutions with adequate amounts of amitraz to effective control ticks in Bureti.
