OMRI Cert.
Small Tank Mixes and Use Rates 

REGALIA® products are active against both soilborne 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.


Complex and Unique Mode of Action

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.

* FRAC (Fungicide Resistance Action Committee) codes can be found here:

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.
