Pre-Vail™

Pre-Inoculant



Capture more nitrogen for improved seedling growth

Nitrogen fixation is a critical component for producing higher yields in alfalfa and other clovers. Pre-Vail™ is a ready-to-use, clay-based pre-inoculant designed to improve early seedling vigor through increased root development and excellent nodulation. Pre-Vail not only contains high levels of rhizobium for nitrogen fixation – 100 million viable cells per gram – but it’s also infused with azospirillum bacteria, an organic biological plant growth promoter.

The details
  • Used as a pre-inoculant on seed in a seed build-up coat
  • Infused with an additional 100 million azospirillum brasilense cells per gram to help boost plant health and improve stand establishment
  • All formulations available in the United States have been listed by the Organic Materials Review Institute (OMRI)

Application Guidelines

Always read and follow label instructions and restrictions before use.

Application Instructions

Use Pre-Vail to inoculate only the supported legume(s) found on the label.

Dry Application

Pre-Vail should be applied to dry, clean seed. Do not use water or any sticking agents or adhesives to wet the seed. Pre-Vail will adhere to the seed naturally.

Coating Application

Pre-Vail can be used as a pre-inoculant in seed coating or build-up process. It is important to allow the seed coat to be permeable by oxygen.

Re-Inoculation of Previously Inoculated Seed

Slowly screen seed to shake off excess inoculant material, then re-inoculate with Pre-Vail, following the recommended application rates and expiration dating.

Inoculation of Seed Mixtures

First, inoculate each legume seed component of the mixture separately, using the appropriate rhizobial strain for each legume. Then, blend the pre-inoculated components together into final seed mixture for bagging.

See label for full list of registered plants and application rates.

Compatibility

Pre-Vail is compatible with most fungicide seed treatments when applied dry. Contact a Verdesian representative at 800-350-4789 for a complete list of compatible fungicides.
