  • Applications

    Kresoxim-Methyl (CAS 143390-89-0) is a systemic agricultural fungicide used to protect a wide range of crops from fungal diseases. As a QoI inhibitor in the strobilin family, it disrupts fungal respiration, enabling preventive and early infection control. It is typically applied as foliar sprays in field and greenhouse crops, with formulations suited for agricultural use. Target crops include fruits (including tree fruits and grapes), vegetables, cereals, and ornamentals, where it helps reduce foliar and fruit infections. It is commonly incorporated into rotation programs and may be tank-mixed with other fungicides to broaden control spectrum and manage resistance. Its use is subject to local regulations and the label directions of the product.
