Plant diseases are divided into three categories: fungal diseases, bacterial diseases and viral diseases. How to accurately distinguish the various diseases of plants is of great significance for the timely and effective disease prevention and control. In the past, in the agricultural planting activities, to diagnose various diseases of plants, it is necessary to train a pair of "eyes of fire", and now we can use the plant pathogen detector to conduct scientific analysis, real-time diagnosis, and timely detection of early treatment. The fungi that make crops sick are some filaments. The bacteria are single cells. The virus is a molecular organism without cell structure. Their metabolism and temperament are also very different. For different diseases, the symptomatic agents are different. And the earlier the plant disease is discovered, the earlier the prevention, the smaller the loss, so the basic policy of plant disease prevention and treatment is early detection and early treatment. In order to effectively improve the control effect of plant diseases and reduce disease losses, the current agricultural field has focused on strengthening the diagnosis of plant diseases, using advanced scientific instruments such as plant pathogen detectors to diagnose diseases of plants, providing a basis for guiding scientific drug use. The effect of reducing drug control. The plant pathogen detector is also called a plant disease detector. It is a professional instrument for the diagnosis of plant diseases, and is also a good helper for plant diseases prevention and control in modern agriculture. In the past, due to the delay and uncertainty of artificial diagnosis, it caused serious economic losses of diseases and led to the abuse of chemical agents, which caused a series of development problems. Now, the use of plant pathogen detectors not only greatly improves the detection. Accuracy and accuracy of medication, and also greatly advance the time of plant disease prevention and control, effectively improving the effectiveness of disease prevention and control. In addition, it should be emphasized that plant diseases occur in the three aspects of environment, pathogens and plants. Therefore, scientific disease prevention and control needs to be handled from these three aspects in order to achieve better control effects. On the basis of the inherent characteristics of natural starch, in order to improve the properties of starch and expand its application range, physical, chemical or enzymatic treatment is used to introduce new functional groups on starch molecules or change the size of starch molecules and the properties of starch granules. Thereby changing the natural characteristics of starch (such as: gelatinization temperature, thermal viscosity and its stability, freeze-thaw stability, gel strength, film-forming, transparency, etc.), making it more suitable for certain application requirements. This starch that has undergone secondary processing and changed its properties is collectively referred to as modified starch.
