Oxazosulfyl is a novel insecticide originally discovered and developed by Sumitomo Chemical Co., Ltd. It belongs to a new chemical class, the “Sulfyl” group, structurally characterized by its ethylsulfonyl moiety. In rice nursery box application, it exhibits excellent control against a broad range of major rice insect pests, including Hemiptera, Coleoptera, Lepidoptera and Orthoptera. Field studies in in-house and contracted rice paddy fields demonstrate that oxazosulfyl is highly effective against local populations of planthoppers that have developed high resistance to existing insecticides. Oxazosulfyl was registered as “ALLES® granule”, which contains 2.0%(w/w) oxazosulfyl, in April 2021 in Japan.
