Plant diseases are one of the most important disease disasters in agricultural production, and have a significant negative impact on crop production and quality. For the prevention and control of plant diseases, only the right medicine can strictly control its harm and reduce the damage. In the past, the diagnosis of plant diseases was judged by observing the symptoms of plant diseases on plants, and now the diagnosis of plant diseases is based on scientific instruments- plant disease detectors , through detection and data analysis to understand plants. Whether it is sick and what kind of disease.
The occurrence and development of plant diseases will generally go through several stages. First, the plants are affected by pathogens or external conditions, and then the internal physiological activities of the plants change, that is, the metabolic reactions in the cells change. In the end, it leads to abnormal state of growth and development of plants, and shows symptoms in appearance. In the past, it was only in the last stage that it can guide plants to disease. Therefore, measures taken at this time often have little effect and it is difficult to stop loss. Now, using plant disease detectors to do "physical examinations" on plants, it is possible to diagnose diseases in the early stages of plant disease, that is, by analyzing physiological changes in plants, which can greatly improve the timeliness and effectiveness of plant disease control. Sexuality, improve the control effect of plant diseases.
In principle, the plant disease detector makes the diagnosis of plant diseases scientific and timely, so the prevention and control is more timely and effective, and the control effect will be better. The practical application also shows that the plant disease detector has an important role in enhancing the level of agricultural disease prevention and control. . In addition, because the plant disease detector can accurately identify the type and type of plant disease, it can guide targeted scientific drugs, which not only effectively alleviates the problem of pesticide abuse, reduces chemical pesticide pollution, and reduces agricultural production costs. Achieve the effect of cost-saving.
