There are many types of plant diseases. If they cannot be detected and discriminated early, then they may cause greater agricultural losses. However, in contrast to the method of visual identification, the use of plant fungal detectors for the diagnosis of crop diseases enables the early detection of plants. Diseases, and accurately identify the types of plant diseases, thus helping agricultural workers to formulate drugs, improve the effectiveness of disease prevention and control.
In the past, plant diseases were diagnosed mainly by observing the symptoms of the field and distinguishing the type of plant diseases and the severity of the infection from the disease symptoms of the plants. For example, viral diseases and non-invasive diseases (physiological) all performed in full. Symptoms of the plant; fungal and bacterial diseases, mostly localized, from the symptoms of disease on the disease, fungal diseases can often be seen mold, powder, black spots (grain) and other symptoms; Bacterial diseases can be seen when the adhesive is damp (bacterial pus); viral and nematode diseases have no symptoms, but there are special symptoms such as mosaic, shrinkage, dwarfing, root swelling.
However, due to the similarities in the disease characteristics of many plant diseases, it is easy to misjudge plant disease symptoms from plant diseases, increase the probability of wrong use of drugs, and the judgment of the symptoms can not be quantitatively analyzed. The guidance is limited. However, the use of a plant fungal detector can not only accurately determine the type of plant diseases, but also perform quantitative analysis from within the plant, and it can also detect plant disease infestation at the early stage of disease occurrence, which improves the prevention and control of diseases. Sex is conducive to formula drug use, precise drug use, enhance prevention and control effects, and can also play a significant preventive role in the occurrence of large areas of plant diseases, and truly achieve early detection, early treatment and scientific prevention and control.
