Kresoxim-methyl [(E)-Methyl 2-(methoxyimino)-2-(o-tolyl)acetate] is a specialty strobilurin fungicide used as an active ingredient in agrochemicals to protect a wide range of crops (e.g., cereals, fruits, vegetables, grapes) from fungal diseases such as powdery mildew, rusts, and leaf spots. It inhibits mitochondrial respiration in fungi by binding to the Qo center of cytochrome b, offering protective, curative, eradicant, and antisporulant action, thereby enhancing crop yield and quality. Its unique structure enables translaminar and systemic movement within plants. Additionally, it is used in research and development for new fungicide formulations and resistance management studies.
