Extracts mixtures of Tv + As (2:1, w/w) and As + Ps (2 : 1, w/w) were about 1.67 times more effective than Tv + Pr (2:1, w/w) extracts mixtures. Based on combination index at 72 HST, extract mixtures of Tv + As and Tv + Pr had low sinergistic joint action, meanwhile As + Pr extract mixture had additive joint action.
