A survey concerning cattle tick control in Queensland. 3. Chemical control.

Survey results concerning chemical control of the cattle tick (Boophilus microplus) in Queensland are reported in detail, and differences due to region, breed and type of enterprise are discussed. The results show that chemical control was more intensive in Zebu and Zebu crossbred cattle than could be justified economically and that a minority of producers with European cattle carried out strategic dipping. Owners of plunge dips did not make regular use of testing facilities, available from the Department of Primary Industries or the chemical companies.
