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

Plant extract	Mean mortality (%)	Corrected mortality ±SEM (%)
Maerua edulis (L) water	32.5	27.2 ± 8.54^c
Maerua edulis (L) butanol	2.0	5.7 ± 0.41
Maerua edulis (L) chloroform	100.0	100.0 ± 0^a
Maerua edulis (L) hexane	51.5	47.7 ± 18.53^b
Maerua edulis (T) butanol	96.3	96.0 ± 2.39^a
Maerua edulis (T) chloroform	100.0	100.0 ± 0^a
Maerua edulis (T) hexane	100.0	100.0 ± 0^a
Amitraz (positive control)	100.0	100.0 ± 0^a
Diluent (negative control)	7.2	–

Corrected mortality values with different superscript letters within the column are significantly different (P < 0.05)
