JMS Stylet-Oil is a premier white mineral oil used for the control of fungal diseases, aphid-transmitted plant viruses, and phytophagous insects and mites. The active ingredient is paraffinic oil at 97.1%. It is suitable for use on a wide variety of crops, including fruit and nut trees, vegetables, field crops, and ornamental plants. The product works by contact and is applied via spray application. For insect control, it is often applied at the onset of pest appearance or during specific growth stages like bloom. For fungal diseases, it is used as a preventative or curative measure depending on the specific disease and crop. When using this product, ensure thorough coverage of leaf surfaces. Note that this product is a petroleum-based oil; avoid applying when temperatures are below 50°F or when plants are under heat or moisture stress. Always follow specific rate and timing instructions for the target crop to avoid phytotoxicity.
