How DURALEV Works
DURALEV trains crops to defend themselves. Its active ingredient, Cerevisane®, mimics a pathogen attack to activate the plant’s natural immune system as a Systemic Resistance Inducer.
Systemic Resistance Inducer
DURALEV helps prime specialty crops before disease pressure takes hold, supporting a stronger natural defense response against a wide range of fungal and bacterial pathogens.
Cerevisane® mimics a pathogen signal, helping prepare the crop’s defense system before pressure escalates.
The primed plant is better positioned to respond to fungal and bacterial disease pressure as part of a preventive crop protection program.
DURALEV fits into rotations, tank mixes, and season-long programs without adding residue concerns.
Program fit: Use DURALEV preventively to help support season-long disease management while maintaining flexibility across spray programs.
Product Details
DURALEV is built for preventive disease management, combining a biological fungicide and bactericide product profile with a Systemic Resistance Inducer mode of action.
How It Works
DURALEV trains crops to defend themselves before disease pressure takes hold. Its active ingredient — Cerevisane® — mimics a pathogen attack to activate the plant’s natural immune system as a Systemic Resistance Inducer.
This process primes specialty crops so they are better prepared to defend against a wide range of diseases.
Program fit: Use DURALEV preventively to support broad-spectrum crop defense, crop safety, and residue-free confidence in organic and conventional programs.
Proven Results
Applied throughout the season, DURALEV provides consistent disease suppression on its own. In a program, it supports strong disease control while adding new modes of action. It can also help reduce overall chemical fungicide load.

Across all crops and diseases
*Program results reflect DURALEV used within a disease-management program. Trials were conducted from 2013–2025 in the U.S. and Europe.
Program Guidance
Key application, compatibility, residue, and performance details to help position DURALEV within preventive disease-management programs.
Program fit: Use DURALEV preventively and reapply as needed to support consistent plant defense activation throughout the season.
Crop & Disease Coverage
DURALEV supports a broad range of labeled crop groups and targeted diseases, making it easy to position across specialty crop programs.
Approved Crops
Broad crop coverage for preventive disease-management programs.
Targeted Diseases
Preventive support against fungal and bacterial disease pressure.
Note: Brown Rot, Downy Mildew, Early Blight, Late Blight, Powdery Mildew, and Sour Rot are highlighted because DURALEV performed exceptionally strong against these diseases in trials.
