Protect your plants from disease!

Reliant® Systemic Fungicide contains the active ingredients mono- and di-potassium salts of phosphorous acid (45.8%). Choose your desired size below. Use Reliant® to control diseases caused by the pathogen phytophthora. Diseases associated with this pathogen include sudden oak death (SOD), downy mildew, pythium, root rot, and fire blight. Reliant® works well on vegetables, citrus, fruit and nut trees, ornamentals, landscaping, turf, conifers, and bedding plants. Reliant® works as both a preventative and curative. You can use this product as a soil drench, foliar spray, soil incorporation, basal bark treatment, or as a bare root dip. Apply it to healthy plants to help them resist disease. For affected plants, it helps the plant kill the invasion while protecting new growth. Reliant® acts quickly, saving your plants from disease-related damage or death. Combine this product with Pentra-Bark® for maximum effectiveness against sudden oak death. Completely review the product label in the links section below for application rates. Rates vary depending on the crop and application.
