REGALIA® advanced biofungicides activate a plant’s natural defenses to protect against a variety of fungal and bacterial diseases, resulting in higher quality AND yields. REGALIA® products are active against both soil borne and foliar pathogens, delay the development of resistance, and help minimize chemical residues. They can be used as stand-alone products or in combination with other fungicides to strengthen integrated pest management programs (IPM) and to help manage resistance in a wide range of organic and conventional crops, as well as in turf and ornamentals. REGALIA® biofungicides have a unique and complex mode of action, referred to as Induced Systemic Resistance (ISR), and carry a FRAC code of P5. ISR creates a defense response in the treated plants and stimulates additional biochemical pathways that strengthen the plant structure and act against the pathogen. When applied to crops, REGALIA® products activate ISR and induce the plants to produce specialized proteins and other compounds—phytoalexins, cell strengtheners, antioxidants, phenolics, and PR proteins—which are known to inhibit fungal and bacterial diseases and also improve plant health and vigor. Re-entry 4 hours, pre-harvest interval 0 days.

    Regalia has many uses

    Posted by David Brogan on 2nd Apr 2020

    I use this biofungicide in the landscape in my tree spray business. It prevents all the diseases I come to control. Use it early injected in the root zone to control Verticillium and Phytophthora. Spray the leaves to control anthracnose, rust and most other diseases.

    Amazing product

    Posted by David Brogan on 28th Oct 2019

    For four years now I have been using Regalia to treat difficult diseases such as Verticillium and Phytophthora in the landscape. I inject it into the root zone along with Neptune's Harvest Fish Fertilizer. This combination is astounding at stopping Verticillium Wilt and other difficult canker deseases. I do the treatment early in April and every 4 weeks thereafter until July. No other fungicide that I have tried has such amazing results.
