Nchu, Felix; Magano, S.R. (Solomon Ramagoai); Eloff, Jacobus Nicolaas (Agricultural Research Council, ARC-OVI and the University of Pretoria, 2012-03-30)In this study we examined the anti-tick properties of the essential oil of Tagetes minuta L. (Asteraceae: Asterales) against Hyalomma rufipes ticks. We obtained the essential oil of T. minuta by hydro-distillation of a ...
