Acerbo® by Bayer is a high-performance dual-mode fungicide combining Fluopyram (SDHI – FRAC Group 7) and Trifloxystrobin (Strobilurin – FRAC Group 11). This advanced combination provides both systemic and translaminar action, ensuring deep penetration into plant tissues and uniform protection across new and existing growth.

It works by inhibiting key processes in fungal energy production and spore germination, effectively stopping disease development at multiple stages. Acerbo® is widely trusted for its consistency under variable environmental conditions, making it suitable for intensive disease pressure situations across major crops.
