In the process of agricultural disease prevention and control, spore traps are effective small assistants. It is an important tool for pathogen monitoring, and is mainly used to catch pathogen spores in the air and observe spores in specific areas at fixed points. Since the popularization and application of spore traps in modern agriculture, the frequency and scale of major diseases in agriculture have been effectively controlled, and the quality and efficiency of agricultural production have been significantly improved, which has greatly helped agricultural production. So how does the spore catcher capture and analyze disease spores? How do you predict the prevalence of disease prevention? Here's a brief introduction to the principle of spore traps.

The spore trap adopts the aerodynamic principle, a new technology of one-way countercurrent flow, so that the collection of spores is not affected by the air flow, the collection mouth is aligned with the wind direction, the quantitative air is sucked into the work box, and then the spores are separated from the air flow, so that the agricultural and forestry crops The fungal spores and pollen in the air of the growing area adhere to the following slides, and then they are taken to the laboratory for cultivation and analysis. The analysis of the changes in the number of pathogenic spores in the field can be used to predict whether the degree of disease caused by the crop has been reached.

The above is related to the “principle of spore trapping” introduced by the Agricultural Instrument Network Xiaobian. At present, diseases such as wheat stripe rust, mushroom brown rot, cabbage powdery mildew, downy mildew of spinach, soft celery of celery, potato early blight, tomato stem rot, and bacterial soft rot of carrots are serious hazards to crops. The main culprit for crop production loss and crop failure, and the monitoring information provided by spore traps provides a reliable basis for preventing and forecasting the prevalence of these diseases, and also plays an important role in promoting the reduction of pesticides and control measures in agriculture. As a result, modern spontaneous traps have become a must for disease monitoring in agricultural, forestry plant protection and phytopathology research departments.
