- How?


Production of antimicrobial metabolites: Double Nickel 55® is capable of producing a number of antimicrobial metabolites such as Iturin and Surfactin which inhibit growth of fungi and bacteria.

Competition for space and nutrients: Double Nickel 55® colonizes plant surfaces, occupying space and using up nutrient sources at potential infection sites thus making it difficult for pathogens to get established.

Systemic Acquired Resistance (SAR): Double Nickel 55® can help activate a plants natural defence mechanisms through SAR. SAR is a state of enhanced immunity to infection demonstrated by plants following an injury or presence of inducer organisms like B. amyloliquefaciens (B.a.).
