A highly water-soluble systemic insecticide may kill insect pests quickly; however, it may not provide long-term or sufficient residual activity compared to a less water-soluble systemic insecticide. A less water-soluble systemic may persist longer, but may not be as effective unless the rate is adjusted to compensate for the slower mobility.
