Table 3 Corrected mortality (%) of tick larvae treated with solvent- solvent fractions of the acetone extract (10 mg/mL) of M. edulis leaves (L) or tubers (T) and Amitraz (0.002% v/v) (N = 4)

From: Addition of a surfactant to water increases the acaricidal activity of extracts of some plant species used to control ticks by Zimbabwean smallholder farmers
