Oxazosulfyl, a novel insecticide originally discovered and developed by Sumitomo Chemical Co., Ltd., belongs to a new chemical class, the sulfyl group, structurally characterized by its ethylsulfonyl moiety. It exhibits excellent control against a broad range of major rice insect pests, including Coleoptera, Hemiptera, Lepidoptera, and Orthoptera, through nursery-box application. With a novel structural backbone and mode of action, this insecticide is classified by the Insecticide Resistance Action Committee as the sole member of novel code 37, vesicular acetylcholine transporter inhibitor. A substantial number of field studies in rice paddy fields have demonstrated that oxazosulfyl, registered in Japan in April 2021 as ALLES® granules, is highly effective against populations that have developed reduced sensitivity or resistance to existing insecticides. Given these favorable properties, oxazosulfyl is expected to contribute to the management of insecticide resistance, the reduction of agricultural chemical use, labor savings, and sustainable agriculture as a next-generation insecticide.
恶唑磺酰是一种最初由住友化学株式会社发现并开发的新型杀虫剂，属于一种新的化学类别——磺酰基类，其结构特征为具有乙磺酰基部分。通过秧盘施药，它对包括鞘翅目、半翅目、鳞翅目和直翅目在内的多种主要水稻害虫具有优异的防治效果。这种杀虫剂具有新颖的结构骨架和作用方式，被杀虫剂抗性行动委员会归类为新型代码37（囊泡乙酰胆碱转运体抑制剂）的唯一成员。大量在稻田进行的田间研究表明，恶唑磺酰于2021年4月在日本以ALLES®颗粒剂形式登记，对已对现有杀虫剂产生敏感性降低或抗性的种群具有高效防治效果。鉴于这些优良特性，恶唑磺酰有望作为一种下一代杀虫剂，为抗药性治理、减少农药使用、节省劳动力以及可持续农业做出贡献。
