The invention discloses an LED mixed spectrum plant growth insecticidal lamp and belongs to the field of plant LED illumination. The lamp comprises an LED lamp dot matrix, a single chip microcomputer control system, a shell and an insecticidal power grid. According to the LED mixed spectrum plant growth insecticidal lamp, power distribution of a power source which specific mosquitoes are fond of is obtained by experiments, through a specific algorithm, proportions in a target light source of three primary colors of red, green and blue can be obtained, the duty ratio of three path PWM waves sent by the single chip microcomputer control system is changed, and therefore electric current driven by LED constant current can be changed, the illumination power of an LED is changed correspondingly, and the target light source can be obtained. The technical problems can be solved that a common plant insecticidal lamp is single in color and does certain harm to both beneficial insects and the human body, and certain guidance for pest killing by plants and optimization is provided.
