In plant pathology, rating of disease symptoms is a frequent task to assess disease severity and thus determine e.g. the resistance level of a genotype or the efficiency of a plant protection agent. Symptom rating can comprise symptom counting, in particular if the disease symptoms appear a single spots on the leaf surface, or it can be estimating the diseased area, a process which frequently relies on visual inspection. LemnaTec analytical software can take both tasks and quantiy the number of symptoms as well as the percentage of the diseased area.
Digitising plant pathological assays is a key to to accelerate and standardise the disease rating processes in research, breeding, and product development. Moreover, it serves in plant health monitoring for precision farming.
