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.
