Controlling fungal diseases in soybeans is a major challenge for farmers. As pathogens evolve, many established products are becoming less effective. Farmers have fewer choices and, in some cases, they must adjust the products and rates they use to keep diseases at bay. A nature-inspired fungicide, Haviza™ active gives farmers an option to address immediate disease pressures and add to their toolbox of rotational options for integrated pest and disease management (IPDM). When new mode-of-action groups are introduced, existing products can remain effective at lower use rates for longer, helping to make disease management more sustainable for farmers and the planet.
OUR INNOVATIONHaviza™ Active
A New Fungicide for a More Confident Soybean Season
With every soybean crop cycle, farmers work to make smarter, more effective decisions in the pursuit of a better, more profitable crop. Achieving better outcomes, however, can sometimes be limited by access to the most effective options. This has been especially true when it comes to soybean disease management. As fungal diseases like Asian soybean rust are worsening in key regions, existing treatments are losing efficacy.
Haviza™ active was developed specifically to deliver soybean farmers the new fungicide option they urgently need. Inspired by a naturally occurring soil bacterium, Haviza introduces the first new mode of action group to manage ascomycete and basidiomycete soybean diseases in over a decade. As a new foundation for fungicide rotation programs, Haviza helps farmers gain confidence in managing diseases to produce healthier and more profitable soybean harvests.
A New Kind of Active Ingredient
Haviza™ active offers a completely novel mode of action group (FRAC Group 21), working on a special target site in ascomycete and basidiomycete fungal pathogens that no other fungicide affects. This makes Haviza uniquely effective for managing pathogens with established or emerging fungicide resistance, especially since Haviza is not cross-resistant with other modes of action. Other special advantages include:
Product Performance
- High efficacy against difficult-to-control soybean diseases
- Broad-spectrum activity on early and late-cycle diseases
Innovative, Differentiated Solutions
- New mode of action group in soybeans
- Disease resistance
Easy to Use and Innovative Formulations and Packaging
- Low use rate*
- Flexible use in custom programs
- Superior rainfastness
- Compatible in tank mixes
What Makes Haviza™ Active Unique?
Read the Technical Bulletin for more details about how the innovation behind Haviza contributes to prosperous soybean farming.
First in a new fungicide group
Haviza works on a novel target site in soybean pathogens and is the first member of fungicide Group 21. Haviza helps manage Asian soybean rust and other asomycete and basidiomycete diseases in soybeans, including anthracnose, cercospora, powdery mildew and septoria. Its new mode of action group assignment makes Haviza a powerful partner in rotational programs, to help control these costly diseases that are becoming increasingly resistant to existing products.
Unmatched performance against soybean rust
Asian soybean rust (ASR) is a widespread and growing threat to Brazilian soybean farmers, costing over $2 billion USD in losses per harvest.1 Haviza works systemically to protect plants against ASR and a broad spectrum of other costly diseases including powdery mildew and anthracnose.
Stops infection before it begins
Haviza prevents the germination of fungal spores and stops germination that has begun. In cases where spores are actively germinating prior to application, Haviza halts the germination process and stops pathogen formation of its appressorium, a pressure ram that the pathogen uses to enter the plant. Without the appressorium, infection is prevented.
