use gardening manual, website, get it tested in a laboratory, using a monoclonal antibodies testing kit.
some 'symptoms' of plant diseases can be discolouration, stunted growth, presence of pests, malformed stems

that kind of thing

tobacco mosaic virus can be identified by yellow leaves as the chloroplasts (which make the plant leaves green) turn yellow. This is bad because the chloroplasts trap sunlight which is used for photosynthesis.

What has an agar plate got to do with plant diseases. Agar plates are used in culturing microorganisms not plant diseases and identifying them

Pathogens can be grown on agar plates and viruses can be cultured in controlled conditions. Biochemical tests are then used to identify bacteria and viruses which have been cultured, possibly using testing kits containing monoclonal antibodies.

detection = discolouration, wilting, loss of leaves etc...
identification = garden manual/website, laboratory
