Ultim®-ST: The Ultimate Answer to Pythium & Metalaxyl-Resistant Pythium
Increase your protection against Pythium spp. including Metalaxyl-Resistance with ultim-ST. Backed by independent third-party data from trials across multiple sites, environments, and varieties, this cost-effective organic non-biological fungicide is the ultimate assurance you need.
Pythium Pressure Just Got Relieved
In the presence of Pythium pressure, regardless of the region, soil temperature, or field, growers and researchers who planted seeds treated with ultim-ST for a wide range of crops report:
- Disease control and emergence comparable to conventional treatments
- Increase in overall plant population often with measured higher yields
- Reduces or eliminates the need for replanting or high-density planting
- Cost savings including seed, labor, time, and land resources due to improved emergence and yield
2023 Third Party Field Trials: 9 States | 19 Fields | 5 Crops
Planting raw seeds in Pythium pressure soil is a recipe for disaster for corn, peas, and other crops.
However, when seeds were treated with ultim-ST, the emergence rates were significantly higher in third-party trials conducted in multiple states. Multi-state varietal trials demonstrate that under Pythium disease pressure, ultim-ST consistently delivers higher emergence that matches conventional seed treatments.
