AmyProtec^® 42

Biological Protection Against Soil-Borne Diseases

Containing the rhizosphere-colonizing bacterium Bacillus velezensis (formerly Bacillus amyloliquefaciens FZB42), this biological soil fungicide helps protect crops against soil-borne pathogens while promoting healthier root development. Applied preventatively, it creates a disease-inhibiting protective shield around the root zone by competing with pathogens for space and nutrients while stimulating the plant’s natural defense mechanisms. Compatible with fertilizers and many plant protection products, it is an ideal solution for Integrated Pest Management (IPM) and organic production programs.

Suitable for Organic Production

Fully compatible with organic, residue-free and sustainable crop production systems, supporting environmentally responsible crop protection.

Target Disease Information

Rhizoctonia

(Rhizoctonia solani)

Rhizoctonia is a common soil-borne pathogen that affects a wide range of crops, causing seed decay, damping-off, stem cankers and root rot. Infected plants often show poor emergence, reduced vigor and uneven growth, which can impact crop establishment and yield. The pathogen survives in soil for extended periods, making preventative management and healthy root development essential for effective control.

Erwinia

(Erwinia spp.)

Erwinia species are bacterial pathogens that can cause soft rot and tissue breakdown in susceptible crops. Infection often occurs through wounds or stressed plant tissue, leading to decay, reduced crop quality and storage losses. Good soil health, strong root systems and preventative disease management strategies play an important role in minimizing the impact of Erwinia infections.

Sclerotinia

(Sclerotinia sclerotiorum)

Sclerotinia is a destructive fungal disease that can infect roots, stems and foliage, causing white mold, wilting and plant death. The pathogen produces long-lasting survival structures called sclerotia, allowing it to persist in soil for many years. Early prevention and integrated disease management are critical for reducing disease pressure and protecting crop yield and quality.

Fusarium

(Fusarium oxysporum)

Fusarium is a widespread soil-borne pathogen that infects plant roots and vascular tissue, causing reduced vigor, wilting and yield losses. In garlic, it is associated with basal bulb rot, while in other crops it can lead to root diseases that impact plant establishment and productivity. Preventative management and healthy root development are essential for reducing disease pressure and maintaining crop performance.
