Isobolograms of insecticide activity. Diagonal lines connect doses of equally effective activity for each insecticide when applied alone. Open symbols are for the amount of each insecticide required for the same effect when the two are mixed together at a ratio based on their median-effect doses (± 95% confidence intervals). Points above the matching line indicate antagonistic activity of the insecticides, close to the line indicates additivity of action, and those below the line indicate synergistic activity.
