Flashcards
0/15
Molecular Diagnostics
Utilizing molecular techniques such as PCR to detect and quantify pathogen DNA in plant tissue.
Remote Sensing
The use of drones or satellites to gather information about plant health over large areas.
Microscopic Examination
Use of a microscope to identify fungal spores, bacteria, or other microorganisms causing plant disease.
Visual Inspection
The primary method of diagnosing plant disease involving close observation of symptoms presented on the plant.
Electron Microscopy
Using electron microscopes to visualize plant pathogens at a high resolution.
Nucleic Acid Sequencing
Determining the exact genetic sequence of a plant pathogen to aid in its identification.
Biotests
The use of indicator plants to confirm the presence of certain pathogens through observed reactions.
Serological Techniques
Using antigen-antibody reactions to detect plant pathogens, similar to immunodiagnostic assays.
Metabolic Profiling
Analyzing the metabolic changes in a plant due to pathogen infection, using techniques like mass spectrometry.
Biochemical Tests
Identifying plant pathogens based on their biochemical properties like enzyme activity.
Phytopathometric Methods
Quantitative assessment of disease severity using scales or image analysis.
Soil Assays
Testing soil for the presence and level of specific pathogens to assess risk to plants.
Koch’s Postulates
A classic set of criteria used to link a specific pathogen to a plant disease.
Immunodiagnostic Assays
Techniques that use antibodies to detect the presence of specific plant pathogens, such as ELISA.
Plant Pathogen Culturing
The process of growing a plant pathogen on a nutrient medium to identify it based on colony characteristics.
