Diseases caused by plants are mainly caused by bacteria, fungi, and viruses. However, because farmers do not know what kind of bacteria or virus the disease caused, they will “immediately go to hospital†and spray a lot of pesticides. If there is no targeted medication, then For farmers, a large amount of money is spent on buying pesticides, and the vegetables and crop residues that are planted are also too high. Therefore, the advent of plant disease detectors can accurately diagnose the source of plant infections in the early stage of plant disease and help farmers quickly and accurately. Determining the variety of pesticides used will reduce farmers' losses and increase profits. 90 M3/h Concrete Batching Plants

The principle of plant disease control is to eliminate pathogens or inhibit their occurrence and spread; to improve the disease resistance of host plants; to control or modify environmental conditions, to make them beneficial to host plants rather than to pathogens, and to suppress the occurrence and development of diseases. The general emphasis is on the prevention of plant populations, and comprehensive control measures are taken based on the occurrence and development laws of crop diseases. Each measure must give full play to the favorable factors in the agro-ecological system, avoid unfavorable factors, and avoid public hazards and human and animal poisoning. To reduce the disease below the economically acceptable level and maximize the economic benefits. Prevention methods include plant quarantine, disease resistance breeding, agricultural control, chemical control, physical and mechanical control, and biological control.
