Product Guides and Specifications

Application Tips

  • The non-pesticide containing slurry should ideally be used during the same day of mixing, within a maximum of 24 hours. The temperature of the slurry should not exceed 20°C.
  • Ensure seed is clean to reduce bridging.

For maximum survival of biological components, store treated seed in a cool (can be below freezing), dry covered and unheated storage area close to floor level.

On-seed compatibility of Nodulator IP Plus preinoculant plus Velondis Plus biofungicide is dependent on application method and temperature at which seed is packaged and stored.

When to apply

Product is registered to be used on seed. Product must be applied to seed within 24 hours of being opened.

The maximum safe planting interval is 100 days. 

How much to apply

One 200 SU case of Nodulator IP Plus will treat 4,536 kg (10,000 lbs) of seed.

One 400 SU case of Nodulator IP Plus will treat 9,072 kg (20,000 lbs) of seed.


  Nodulator IP Plus (inoculant + conditioner) Velondis Plus
Rate per 100 kg seed 130 ml5

4.4 ml



5 Please refer to the product label for application rates without pesticides, as 134.3 ml/100 kg is not sufficient for even seed coverage and requires additional liquid volume (water and/or pesticide). 


Directions for use

When applying as a standalone treatment (no seed treatment)

With slurry tank agitator (or re-circulation pump) turned on, thoroughly mix the appropriate volumes of Nodulator IP Plus liquid inoculant with the Nodulator IP Plus conditioner, then add the separately packaged Velondis Plus biofungicide and non-chlorinated6 water. Continuous and gentle agitation throughout the mixing and application process will enhance application and survival characteristics.

Calibrate pumps and metering system to apply a total of 326 ml/100 kg to seed.

6 Municipal water sources do contain chlorine; however, it can be used in combination with biologicals if allowed to sit exposed to the environment (e.g. in open tank) for a minimum of 24 hours to allow for chlorine to gas off.


When applied with additional seed treatment(s)

Nodulator IP Plus preinoculant and Velondis Plus for soybeans must be applied at a rate of 134.4 ml/100 kg (2.0 fl oz per 100 lbs) of seed with no additional water if the total liquid volume being applied (Nodulator IP Plus, plus all other seed treatment actives/polymers/colourants) is at least 326 ml/100 kg (5.0 fl oz per 100 lbs) of seed.

Both a wet sequential (also known as simultaneous), using a separate application tank for the active chemicals/polymers/colourants (preferred), or a tank mix can be used as application methods for this product.

If a tank mix application method is used, do not slurry the mixture for greater than 4 hours prior to application to the seed.

For extended days on-seed, we only recommend a wet sequential (also known as simultaneous) application and keeping the inoculant in a separate application tank. In this tank, the inoculant must be applied within 24 hours.
