Double Nickel's active ingredient, *Bacillus amyloliquefaciens* strain D747, features five modes of action: anti-fungal, anti-bacterial, growth promotion, plant triggering, and competitive exclusion. Researchers have put Double Nickel to the test by performing 700 lab and field trials with over 74 different crops or ornamentals, and Double Nickel has proven efficacy in the treatment of more than 90 different diseases. It is NOP approved, OMRI listed, residue exempt and made in the USA.
