Abstract
Systems, devices, and methods for detecting agrochemicals in environments associated with agricultural equipment are described. Certain agrochemicals that are formulated for being detected using the systems, devices, and methods disclosed herein are also described. The devices, systems, and methods disclosed herein are generally configured to use spectral characteristics to detect agrochemicals in an environment associated with agricultural equipment. The spectral characteristics can be analyzed in various ways to provide different types of information about the agrochemicals and/or the environment.
Claims36
A method for detecting a counterfeit agricultural composition, the method comprising:
- receiving light from a light source after the light has been transmitted through or reflected by at least a portion of a suspected counterfeit agricultural composition and measuring intensity of the received light as a function of wavelength to obtain spectral characteristics of the received light;
- obtaining an absorbance spectrum from the suspected counterfeit agricultural composition;
- and
- comparing the absorbance spectrum obtained for the suspected counterfeit agricultural composition to a reference absorbance spectrum for a genuine agricultural composition, wherein the genuine agricultural composition comprises an agrochemical and a tracer dye or a tracer pigment and wherein the reference spectrum has an absorbance maximum (Amax) for the dye or the pigment at one or more wavelengths;
- wherein in the absorbance spectrum for the suspected counterfeit agricultural composition, less intensity in comparison with the reference spectrum at said one or more wavelengths at which the reference spectrum has the Amax indicates that the suspected counterfeit agricultural composition is a counterfeit composition.
