  • Electrostatically sprayable insecticidal formulations
    Patent number: 4316914
    Abstract: An electrostatically sprayable insecticidal formulation comprising a solution of from 0.5 to 50% of permethrin or like compound in an organic solvent medium, the medium being formulated so that the formulation has a resistivity at 20.degree. C. in the range 1.times.10.sup.6 to 1.times.10.sup.10 ohm centimeter and a viscosity at 20.degree. C. of 5 to 50 centistokes.
    Type: Grant
    Filed: April 7, 1980
    Date of Patent: February 23, 1982
