Teraxxa® and Teraxxa® F4 Seed Treatments
Get early-season protection from wireworms and other disease pressures so your cereal crops have the best chances to succeed. Teraxxa® and Teraxxa F4 seed treatments are the only products that can rapidly help eliminate wireworms in wheat across all species and developmental stages.
Featuring the active ingredient, Broflanilide, these are effective wheat seed treatments, outperforming and outlasting neonicotinoid insecticides. They’re proven to eliminate wireworms in wheat. Those reduced populations have a positive benefit on rotational crops, too, helping to improve yield potential.
Benefits of Teraxxa and Teraxxa F4 Seed Treatments
- Proven wheat seed treatments that eliminate wireworms
- Rapidly effective in the field for all cereal crops, including wheat, barley, oats, rye and triticale
- Proven to be beneficial to rotational crops as well
- Reduces resident wireworm populations and breaks their reproduction cycle
- Partners with systemic insecticides for additional protection from above-ground insect pests

How Teraxxa and Teraxxa F4 Seed Treatments Work
Powerful New Active Ingredient:
- While other active ingredients provide temporary intoxication, the new active ingredient in Teraxxa and Teraxxa F4 seed treatments, Broflanilide, quickly controls populations to eliminate wireworms across all species and developmental stages.
Increased Yield Potential
- Wireworms are small, but their impact on your wheat can be significant. They can cause up to 80% in lost yield and stunt the growth of the remaining seedlings. By stopping them from feeding on roots and seedlings, Teraxxa and Teraxxa F4 seed treatments help you control wireworms and maximize your yield potential.
Protects Against Spectrum Diseases Too
- Teraxxa F4 Seed Treatment goes further than just controlling wireworm populations. It utilizes four fungicide modes of action to protect against diseases such as Fusarium root rot and seedling blight so your crops have a healthy environment to grow.

FAQs
Q1: What are the main benefits of Teraxxa and Teraxxa F4 seed treatments?
A: Teraxxa and Teraxxa F4 seed treatments are the only seed treatments that rapidly eliminate wireworms across all species and developmental stages. When left untreated, cereal farmers suffer up to 80% yield loss from wireworms every year. Wireworm populations can grow rapidly, multiplying 11,000% over three years, so eliminating them rapidly on contact is critical to protect yield potential. Teraxxa F4 seed treatment also benefits rotational crops. While it isn’t active after harvest, the benefits of reducing wireworms during the growing season are apparent in the following crop.
Q2: What are the key differences between Teraxxa and Teraxxa F4 seed treatments?
A: The key difference is that Teraxxa F4 seed treatment includes four fungicides for broad-spectrum disease control against seed and soilborne diseases, including Fusarium, Rhizoctonia and Pythium, versus Teraxxa alone. Teraxxa F4 seed treatment also has a strong cold tolerance and unique systemicity of Xemium® fungicide for longer and more complete protection.
Q3: What is Teraxxa F4 seed treatment, and how does it work?
A: Acting as your first line of defense against wireworms, Teraxxa F4 seed treatment is a proven product that rapidly eliminates all wireworm species and reduces resident populations. In addition, it offers broad-spectrum control against seed and yield robbing diseases including Fusarium, Rhizoctonia and Pythium.
Q4: How is Teraxxa F4 seed treatment different from other wireworm treatments?
A: Unlike any other wireworm treatment, Teraxxa F4 seed treatment exploits the weakest link in a wireworm’s nervous system, causing quick mortality across all species and developmental stages. When applied year after year, Teraxxa F4 reduces wireworm populations, supporting uninterrupted yield potential.
Q5: What diseases does Teraxxa F4 seed treatment protect against?
A: Wireworms are not the only yield robbers in your soil. Fusarium root rot, seedling blight, Rhizoctonia root rot and Pythium are all diseases that can contribute to poor soil health. Teraxxa F4 seed treatment helps eliminate these diseases, helping to keep the plant strong to better tolerate other environmental stressors and improve yield production.
Q6: Can Teraxxa F4 seed treatment be used in crop rotation strategies?
A: Teraxxa F4 seed treatment is uniquely beneficial in crop rotations. Since wireworms multiply 11,000% over three years, multiple crops are susceptible to wireworm feeding as growers rotate between crops. Research has found that crops following a field previously treated by Teraxxa F4 seed treatment have a 24 lbs/A yield increase compared to fields that were not treated the year prior1. Reducing the wireworm population during one growing season can directly impact the next.
