Rhipicephalus microplus is a widely distributed tick species that causes direct and indirect losses to cattle production; therefore, the control of tick infestations is essential. Correct treatment methods are necessary to avoid overdosing or underdosing of chemical acaricides and control tick resistance. Moreover, studies that highlight the factors associated with the efficacy of chemical products are extremely necessary. Therefore, this study aimed to evaluate the effects of precipitation intensity and time on the efficacy of topical application of acaricides. Engorged females were collected from cattle on farms located in Rio Grande do Sul, Brazil and treated with Colosso FC30® Ouro Fino Animal Health (15% cypermethrin, 30% chlorpyrifos, and 15% fenthion). After 30 min, 1 h, 2 h, 3 h, 6 h, 9 h, 12 h, or 24 h of treatment, they were subjected to simulated precipitation at mild and intense, for each time. The results showed 100% acaricide efficacy for all the evaluated groups and demonstrated that precipitation from 30 min after treatment and at any intensity, did not affect the efficacy of Colosso FC30. Therefore, this study clarified the influence of simulated precipitation on the efficacy of topical Colosso FC30 treatment towards the R. microplus control.
