The occurrence of crop diseases can generally be divided into patches and spotting, but no matter what kind of situation it will affect the growth of crops, thus affecting the yield and quality of agricultural production, so as to detect the occurrence of plant diseases as soon as possible, And to minimize its hazards, modern agriculture uses a professional and scientifically-enhanced crop disease diagnostic equipment to perform crop disease detection work, which effectively ensures the disease control effect and the benefits of agricultural production. Agricultural production has increased and increased production has laid a solid foundation.
We can see from the application of crop disease detection diagnostic, prevention and treatment of plant diseases in our country experienced a "cure all" to "disease prevention" period of development, "cure all" that is, when the emergence of diseases of crops symptoms, prevention and treatment began again, the goal is to destroy pathogens, thus resulting in a large number of chemicals put into agricultural production, it produced a series of negative effects, resistance to plant pathogens are increasingly strong control effect is getting worse. Modern people have a deeper understanding of plant diseases and began to realize that the plant protection policy of “disease-free prevention, comprehensive prevention and control†is correct. Therefore, at present, the grass-roots departments are actively adopting crop disease detection in disease prevention and control in various regions. The diagnostic instrument is used to diagnose crop diseases, so that it is truly disease-free and disease-free.
The biggest difference between the crop disease diagnosis instrument and the traditional crop disease diagnosis is that the crop disease diagnosis and diagnosis instrument determines the disease by diagnosing the physiological characteristics of the plant, instead of determining whether the plant is suffering from the appearance of the disease as observed in the past. Disease, so this method can earlier find the plant disease conditions, but also can accurately determine the type of crop disease, so as to have a certain guiding role in the scientific use of drugs, then often only need less input to get significant prevention and control effect. The application of the crop disease diagnosis and diagnosis instrument also marks that China's plant protection work has entered a new stage of development and is a major contribution to agriculture.
