Botanical photo-activated pesticides were used as insecticides, fungicides and herbicides, whose activity could be increased notably under the sunlight. They were known as green pesticides because they acted as toxicity on pests, degraded itself simultaneously and had no contamination in environment. Photo-activated pesticides now have been applied in the control of hygiene pests successfully and the development tendency is to control the agricultural insects and weeds by modifying the molecule structure and developing the new formulation. Based on the results of researches for more than ten years, the developments and applications of botanical photo-activated pesticides were reviewed in this paper as well as new idea proposed.
