Methomyl-oxime is primarily used as a key intermediate in the synthesis of methomyl, a broad-spectrum carbamate insecticide. It is essential in the manufacturing process for producing pesticides that control pests in various crops, including vegetables, fruits, and field crops, thereby protecting plants from damaging insects and contributing to higher crop yields and better-quality produce. As an intermediate, it is not applied directly in agriculture. Additionally, it is utilized in research and development for studying the efficacy and safety of new insecticidal formulations.
