Abstract
Field experiments on the chemical control of the tick Boophilus microplus (Canestrini) in dairy cattle were conducted in two locations in Puerto Rico in 1984 and 1985. Ectrin 10%, water dispersible, sprayed at 0.05% concentration every 4 weeks on dairy cows, and Ectrin eartags attached on both ears six months after the start of the experiment, were highly effective to control ticks. No secondary effects were observed in the animals after applying Ectrin.
