Key Takeaways
- Nufarm has introduced Pretium™ SDS, a biological seed treatment targeting Sudden Death Syndrome (SDS) and Red Crown Rot (RCR) in soybeans.
- The treatment uses natamycin, a biologically derived fungicide, offering high efficacy without causing phytotoxicity.
- Pretium SDS complements Trunemco, Nufarm’s existing nematode management solution, creating a dual biological protection package.
- Approved for use in Kentucky, Missouri, Ohio, and West Virginia, with regulatory submissions pending in 13 additional states.
- The solution addresses key threats like Fusarium virguliforme and Calonectria ilicicola, both of which can cause significant yield losses.
Nufarm Introduces Pretium SDS to Address Soybean Disease Challenges
Biological Fungicide Offers Protection Against Sudden Death Syndrome and Red Crown Rot
Nufarm has announced the launch of Pretium™ SDS, a new biological seed treatment formulated to combat two major threats to soybean crops: Sudden Death Syndrome (SDS) and Red Crown Rot (RCR). These diseases, caused by soilborne fungi, have been known to significantly reduce soybean yields across multiple U.S. states.
Pretium SDS features natamycin as its active ingredient, a biologically produced compound classified under Fungicide Resistance Action Committee Group 48. Unlike many synthetic treatments, Pretium SDS does not cause seedling stress and is suitable for early-season application in sensitive environments.
“With Pretium SDS, growers now have access to a biological fungicide for SDS and RCR control that is a perfect complement to Trunemco,” said Jeff Kaiser, Technical Services Manager at Nufarm.
Integrated Seed Treatment Option with Nufarm’s Trunemco
Comprehensive Biological Package for Soybean Health
Pretium SDS will be offered as an optional add-on to Trunemco, Nufarm’s biochemical and microbial seed treatment that targets 14 types of parasitic nematodes, including soybean cyst nematodes. Together, the two treatments provide a dual-action biological approach, supporting seedling vigor and early-season root health.
- Trunemco primes plant physiology and provides microbial protection.
- Pretium SDS offers fungicidal activity against pathogens such as Fusarium virguliforme and Calonectria ilicicola.
This combination is designed to help growers manage early-season disease and pest pressure more effectively, leading to stronger stand establishment and more uniform plant development.
Regional Use and Regulatory Path For Nufarm
Initial Approval in Four States, With Additional Submissions Pending
By way of a Section 2(ee) recommendation bulletin, Pretium SDS can currently be used for the suppression of Red Crown Rot in Kentucky, Missouri, Ohio, and West Virginia. Regulatory submissions are under review in several other soybean-producing states, including Illinois, Iowa, Nebraska, and Minnesota.
Red Crown Rot is especially problematic in heavy, clay-rich soils and flood-prone areas, with yield impacts ranging from 15% to 70%, according to university research.
