Plant Disease Diagnostic Instrument

Bacteria, fungi, and viruses are the primary causes of crop diseases. These pathogenic microorganisms typically infect plants through stems, leaves, roots, fruits, and other parts. While most diseases are relatively easy to control during their initial stages, they are often difficult to detect. Once established, disease control becomes challenging and less effective, leading to reduced yields or even total crop failure. Detecting and promptly controlling diseases during their early stages is crucial for preventing their spread.

Detecting plant diseases involves complex chemical and physical processes. Moving from laboratory research to practical application has long been a goal. Plant disease diagnostic instruments can rapidly analyze and identify various crop diseases. They provide scientific theoretical support for disease control and pesticide application, offering significant convenience to farmers and growers.

Plant disease and pest diagnostic instruments operate based on biophysical principles. Typically, healthy plant membranes maintain a potential around -50 mV, with extracellular membrane resistivity at approximately 10⁵ Ω/cm and membrane capacitance consistently around 1 μF.

When crops become infected, this inevitably leads to changes in molecular vibration spectra and an increase in membrane potential. Different pathogens cause distinct variations. Based on this principle, the instrument utilizes electrical conductivity and optical diffraction methods to identify the specific type and category of disease. This technology represents a global first in its field.
