Abstract
Plant eradication and stressing of plants using illumination signaling where a short-time dual component, low energy, unnatural set of irradiances is applied, with no mutagenic or high radiative energy transfers in any wavelength for eradication by substantial high temperature thermally-induced leaf and plant component failure or incineration. An Indigo Region Illumination Distribution of wavelength 300 nm to 550 nm is directed to plant foliage and/or a plant root crown, while infrared radiation that is substantially Medium Wavelength Infrared radiation of 2-20 microns wavelength, 2.4-8.0 microns preferred, is directed to a plant root crown and/or soil immediately adjacent the root crown. The Indigo Region Illumination Distribution can pass through the MWIR emitter to form a compact illuminator that uses specific unnatural irradiances that provide unexpected plant control. The MWIR emitter can comprise borosilicate glass at 400° F. to 1000° F.
