Junction is a broad-spectrum fungicide/bactericide used to control various plant diseases on ornamental plants, turf, and grasses. It contains Mancozeb (15.0%) and Copper (46.1% as copper hydroxide) as active ingredients. It is effective against a wide range of fungal and bacterial pathogens, including diseases like fire blight, anthracnose, and various leaf spots. The product can be used for both indoor (greenhouse) and outdoor applications. For greenhouse ornamentals, it is applied as a thorough coverage spray at a rate of 1.5 to 3.5 lbs per 100 gallons of water. For turf and landscape ornamentals, application rates vary by specific plant type and disease. Handling notes: This product is corrosive and can cause irreversible eye damage. It is harmful if swallowed or inhaled. Always wear appropriate PPE, including long-sleeved shirts, long pants, shoes plus socks, waterproof gloves, and protective eyewear. When mixing or applying, avoid contact with skin and eyes. Do not apply to fruit trees by homeowners. Use caution when applying near masonry or metal surfaces to avoid staining. To manage resistance, rotate Junction with other FRAC Group M1 and M3 fungicides. Always follow specific plant-by-plant instructions provided in the label tables for optimal efficacy and to prevent phytotoxicity.
