An apparatus for detecting nonmetallic debris in plant material collected with harvester equipment. As the plant material is collected, a signal generator transmits a signal capable of distinguishing the nonmetallic debris from the plant material, and a sensor receives the generator signal and produces an alarm signal when the nonmetallic debris is detected. A controller receives the alarm signal and modifies operation of the harvester in response to the alarm signal. Different signals can identify the nonmetallic debris. The signal generator and sensor can function based on energy from laser light waves, from sound waves, microwave, gamma, x-ray, or fluoroscope energy wavelengths.
