The Pesticide Science Society of Japan was organized on October 14, 1975.

The society intends to provide a forum for the exchange of ideas not only on developing pesticides but also on contributing to environmental and life sciences. Sponsored scientific activities are its Annual Meeting, a Pesticide Science Symposium, and workshops and pesticide research where various aspects are considered. At the Annual Meeting where several hundred scientists gather, over hundred papers on such projects as structure-activity relationship, biochemical and toxicological aspects of insecticides, fungicides and herbicides, metabolism, residue analysis, formulation research, and environmental aspects of pesticides are presented. The Pesticide Science Symposium is an umbrella meeting cosponsored by the Pesticide Science Society of Japan, the Science Council of Japan's National Committee of Plant Protection, the Agricultural Chemical Society of Japan, Japanese Society for Phytoregulators, Japanese Society of Applied Entomology and Zoology, the Phytopathological Society of Japan and the Weed Science Society of Japan. Topics related to pesticides are discussed not only by pesticide scientists but also by entomologists, weed scientists, phytopathologists, soil scientists, natural product chemists and crop scientists. Workshops include subjects as diverse as pesticide fate in the soil, residue analysis, formulation and application, rational pesticide design, biotechnology related to pesticide science, bioassay methodology and a forum for young scientists.
