Seed Health



The early stages of any living organism are vital to future growth and development. Seed health technologies offer a range of benefits that ensure the maximum potential of a plant’s growth, including disease-free seeds with the opportunity of increased nutrient uptake.

Seed health technologies offer many benefits including:

  • Larger seedlings with longer, more developed roots
  • Faster speed of emergence
  • Improved uniformity
  • Earlier canopy development
  • Wider temperature range for germination
  • Increased final population
  • Optimized harvesting performance
  • More yield

Product List

Following a successful collaboration with Arysta LifeScience, a leading niche developer and manufacturer of agrochemicals, Germains can now offer an exciting development for the Seed Industry in plant health, in the form of gopure®.

Gopure®  powered by Rancona® Technology,  is proven to have strong efficacy against the seed-borne fungal pathogen Verticllium dahliae, and other soil fungal and seed pathogens. All this, and the additional benefits that seed technologies bring like speedier field emergence and more vigorous uniform seedlings, with the ability to cope with early season stress.

Key Benefits

  • Near to no pathogen found on gopure® treated seed
  • Activity against soil borne pathogens
  • Compatible with Germains’ other technologies and other seed treatments

Seed-borne fungal pathogens severely impact the fresh spinach market by causing foliar symptoms. Dense planting, poor air circulation and low plan fertility increase the severity of these diseases. Cladosporium, Stemphyllium and Anthracnose thrive under wet growing conditions. Germains has treated numerous cultivars from various breeder producers.

Clean healthy seeds are available for spinach growers. Gopure’s efficacy at removing these seed-borne pathogens without impacting seed health is a proven technology.

Why take a chance with pathogen ridden seeds? Start with clean, healthy seeds. gopure® also has the additional benefit of protecting your crop from soil-borne pathogens like Fusarium, Pythium and Rhizoctonia. A good healthy spinach crop starts with gopure®.

The early stages of any living organism are vital to future growth and development. Germains have developed a technology that focuses on early plant nutrition, even before the plant emerges, ensuring its success in variable growing conditions. goseed® maximizes the potential nutrient uptake of the seedling, offering a number of benefits to both the plant and the Grower.

Key Benefits

  • Larger seedlings with increased foliage
  • Enhanced root development
  • Improved vigour for better stand in the field
  • Increased yield potential

Desert Lettuce Trial

For three consecutive years, Germains has been conducting summer Heat Stress Trials and fall Value Justification trails in Yuma, Arizona. The objective is to demonstrate the performance of Germains lettuce desert pellets versus our competitors.

Trial Details

Number of lettuce varieties trialed: 6

Priming: Emergis

Pellets: OxyKote® (10,500 – 13,000 pellets per pound) ProPellet® Heavy (16,000 – 19,000 pellets per pound) – Available in white or tan color

Compared with market standard desert primed and pelleted products


Germains continue to deliver products that outperform competitors’ in early emergence and under high temperature stress, leading to an increase in potential yield and providing benefit to the grower in the field. For improved emergence, and to overcome thermo dormancy, rely on Germains to “Maximize Nature’s Potential”.
