1. A substantially non-invasive low-energy low irradiance non-mutating method for eradicating a plant in a time under one minute, using a Rapid Unnatural Dual Component Illumination Protocol (RUDCIP) with illumination about said plant, said method comprising:

  • [1] An above-ground foliage and root crown damage illumination component comprising exposure to near-IR radiation directed to any of a foliage of said plant and a root crown of said plant, said near-IR radiation of irradiance Enear-IR in W/m2 and a total exposure time Tnear-IR in seconds following a RUDCIP Band (RUDCIP BAND) specification;

    [2] A ground-penetrating UV-A illumination component, comprising exposure to UV-A radiationdirected to any of a root crown of said plant and a soil grade immediately adjacent said root crown;

    said UV-A radiation of irradiance EUV-A in W/m2 and a total exposure time TUV-A in seconds following said RUDCIP Band specification;

    said above-ground foliage and root crown damage illumination component and said ground-penetrating UV-A illumination component each having said exposure times Tnear-IR and TUV-A of under one minute of total operation, respectively;

    said RUDCIP Band specification comprising a Red River Crabgrass (Digitaria cilaris) protocol specification given by
    L=5.5×

    10.6[Enear-IR]*Tnear-IR+6.5×

    10.5[EUV-A]*TUV-A where L is lethality effectiveness expressed in fraction of plants dead in 30 days, such that L is greater than zero and equal to or less than unity;

    said RUDCIP Band specification further specifying that said UV-A irradiance EUV-A is within a factor of three above or below said Red River Crabgrass (Digitaria cilaris) protocol specification, such that said UV-A radiation has an over-riding minimum irradiance EUV-A of 60 W/m2; and

    said RUDCIP band specifying further that said near-IR irradiance Enear-IR is between a maximum of 27,000 W/m2 and a minimum of 270 W/m2.
