Potatoes in Canada

Double Nickel biofungicide now available in Canada

Feb. 12, 2016, Canada – Double Nickel biofungicide is now available for use by Canadian growers of fruiting and leafy vegetables, potatoes, grapes, strawberries, tree fruit and other crops. Double Nickel represents a new generation of fungicides and bactericides that have biologically based active ingredients, are of low risk to the environment and are sustainable crop protection solutions, according to a press release. Manufactured by Certis USA, Double Nickel is registered for use in five countries, including the U.S. where it has been used by American growers for more than two years. 

Double Nickel is a naturally occurring strain (D747) of the beneficial rhizobacterium Bacillus amyloliquefaciens. B. amyloliquefaciens rapidly colonizes roots, leaves and other plant surfaces to prevent establishment of disease-causing fungi and bacteria, such as powdery mildew, Botrytis, bacterial disorders, damping off, and root and crown diseases, such as ythium, rhizoctonia, Fusarium and sclerotinia. 

The release adds that Double Nickel uses multiple non-toxic modes of action to control and suppress diseases. 1) Its metabolites kill fungal pathogens by damaging cell membranes. 2) The metabolites control bacterial pathogens by disrupting cell walls. 3) Double Nickel triggers a SAR/ISR response from the plant prompting it to defend itself against pathogens. 4) Double Nickel prevents infection from pathogens through competitive exclusion. These multiple modes of action make the FRAC 44 biofungicide highly effective in the field. 

Double Nickel is of low risk to bees and beneficials, according to the press release. It has a four-hour re-entry, can be applied up to and including the day of harvest, at low use rates. Double Nickel is residue exempt, so there are no minimum residue level (MRL) issues limiting the export of treated crops. 

The biofungicide is available as Double Nickel 55 WDG and in a liquid concentrate (LC) formulation. Double Nickel 55 leaves no visible residue on the crop. 

Double Nickel 55 WDG and Double Nickel LC will be distributed exclusively by UAP Canada.
