Biofungicide approved for use in Canada

Health Canada’s Pest Management Regulatory Agency has approved Regalia Rx biofungicide for use on wheat and soybean in Canada.

The Regalia product portfolio, with all formulations based on an extract of Giant Knotweed (Reynoutria sachalinensis), is a suite of preventative biofungicides for use on both conventional and organic crops. Regalia products prevent and fight diseases by triggering treated plants to produce disease-fighting biochemicals (induced systemic resistance), while simultaneously increasing leaf chlorophyll content to enhance plant health, crop yield and crop quality. Regalia Rx is not harmful to workers, food, beneficials and pollinators, according to a company press release, and can be sprayed right up to harvest to manage residues for export. Regalia Rx also has the minimum restricted-entry interval for workers to enter the field after spraying, increasing operational flexibility.

The Regalia Rx label is for suppression of Septoria leaf spot on wheat and aerial web blight (Rhizoctonia solani), Alternaria leaf spot, frog-eye leaf spot (Cercospora sojina) and white mould (Sclerotinia sclerotiorum) on soybeans.

Marrone Bio Innovations (MBI) has an agreement with Koch Agronomic Services to distribute Regalia Rx brands in the United States and Canada for large acre crops, such as wheat, soybeans, corn and alfalfa.
