Chrysanthemum morifolium pest and disease control is ushering in a green transformation, and biological control technology has become a key solution due to its environmentally friendly characteristics. This study comprehensively sorted out the current mainstream biological control systems, covering multiple dimensions such as microbial antagonism, natural enemy regulation, botanical pesticides and ecological management, deeply analyzed their mechanisms of action and evaluated their application prospects. In the field of microbial control, Bacillus subtilis and Trichoderma harzianum have shown excellent disease inhibition capabilities. These beneficial microorganisms work through a dual mechanism: on the one hand, they secrete antimicrobial active substances to directly inhibit pathogens, and on the other hand, they activate the plant's own immune defense system. Natural enemy insects such as ladybugs and lacewings have built a natural pest control network, which has a significant control effect on common pests such as aphids and red spiders. In terms of botanical pesticides, natural ingredients such as matrine and tea tree essential oil have attracted much attention due to their broad-spectrum antibacterial and insect repellent properties. Field practice has confirmed that the integration of multiple biological control methods can produce a synergistic effect and achieve a win-win situation of economic benefits and ecological protection. This study not only provides a systematic solution for the green production of chrysanthemum, but also provides a practical example for promoting sustainable agricultural development.
