FS formulations are now the most popular type of seed treatment because they are concentrated formulations and are safer to apply as they are water based.
Seed treatment formulations usually contain multiple active ingredients and/or high loading levels. Additionally, the active ingredient has to be accurately and evenly spread over the seed surface and must remain there throughout storage, drilling and while the seed starts to germinate. To successfully develop these types of formulations, superior formulation additives are essential. The high performance requirement and complexity of seed treatments means formulating is the focal challenge. We simplify formulation development with our Seed Vision™ range which brings seed treatment innovation into focus.
The use of polymeric dispersants are highly recommended due to their higher molecular weight, large repulsive barrier and many anchoring groups per molecule. This enables highly loaded, stable seed treatments to be formulated.
A modified styrene acrylic polymeric aqueous dispersant in liquid form which exhibits excellent hard water tolerance.

If an FS is not properly structured, the formulation can breakdown resulting in solid particles settling to the bottom of the formulation. This leads to reduced shelf life stability and poor performance in the field. The inclusion of a rheology modifier helps overcome this issue by increasing the viscosity of the formulation, providing improved stability. Please note Atlox Rheostrux™ is not EPA cleared.
It is important to include a wetting agent as during the milling process, fresh surfaces are generated which are generally of non-polar nature and will flocculate together rapidly. This could lead to increased viscosity and even mill blockage. Including a wetting agent overcomes this as it replaces air and prevents agglomeration, allowing dispersants to perform. Wetting agents can also provide some dispersion.
