Better establishment with SYNFLO seed treatment technology. SYNFLO Seed treatment, from Synergy Seeds, developed for successful nodulation and establishment of pasture legume seeds.

SYNFLO consists of:


Strain specific live bacterial rhizobia to suit individual crops are applied directly to the seed. Rhizobia are a group of soil bacteria that infect the roots of legumes to form root nodules. They produce nodules in the legume which fix nitrogen gas (N2) from the atmosphere turning it into a more readily useful form of nitrogen. The nitrogen is exported from the nodules and used for growth in the legume. A well nodulated legume plant will aid in strong plant growth and reduce the need for additional artificial nitrogen to achieve high level of forage production.


  • During the critical establishment phase, soil borne diseases, such as pythium, can impact heavily on successful plant numbers. In many cases Pythium has detrimental effects on plant numbers before seedling emergence, resulting in high plant mortality
  • Pythium root fungus is commonly known as damping off and is responsible for many seedling establishment failures in both Sub Clover and Lucerne plants
  • SYNFLO comes standard on registered products with Axy-M Fungicide for the control of seedling disease caused by Pythium
  • The added insurance with this Fungicide package gives growers greater confidence at seeding to achieve a better crop outcome

Nutrient Package

  • Targeted starter Plant nutrition is key for all establishing seedling crop and SYNFLO Seed treatment comes standard with a full package of Macro and Micro Nutrients
  • Nutrients such as:
  • Phosphorus (P)
  • Potassium (K)
  • Zinc (Zn)
  • Iron (Fe)
  • Nitrogen (N)
  • Manganese (Mn)
  • Sulphur (S)
  • Boron (B)
  • Magnesium (Mg)
  • Copper (Cu)
  • Molybdenum (Mo)
  • This base program helps produce more resilient plants to handle abiotic stresses for a stronger pasture stand into the future

Calcium Carbonate lime

  • Calcium carbonate lime is an important element to the SYNFLO Seed treatment package. The Lime is a carrier to host the critical live rhizobia around the seed. This provides a longer shelf life on the pre inoculated seed when compared to film coats
  • Calcium Carbonate is hygroscopic, which strongly attract moisture from its surroundings to the seed in the furrow for an even and quicker establishment in tougher growing conditions
  • SYNFLO offers an added benefit of protecting the live rhizobia from toxic fertilisers in the seeding furrow
  • Calcium Carbonate helps to improve the survival of rhizobia into acidic soils at establishment
  • SYNFLO has better seed flowability through all types of seeding units when compared to slurry treated products

Polymer coating

  • SYNFLO Seed treatment has a tougher, durable coat with reduced dusting
  • Polymers encapsulate the vital rhizobia, fungicide and nutrient package around the seed to maximize the viability of every seed
  • Strong seed performance at seedling stage allows for a long-term pasture and lucerne stand

SYNFLO Offers:

  • Strong agronomic focus with Rhizobia, Fungicide and Trace Element package
  • Flexibility at seeding time with a wider sowing window to meet the ever-changing climatic conditions
  • Ready to use straight from the SYNFLO bag – no additional inputs required for the farmer
  • Stronger seedling performance in adverse conditions
  • Successful nodulation with strain specific rhizobia and nitrogen fixation
