Filmcoat elite is a new upgraded conventional filmcoat scientifically formulated for carrots and jalapeno peppers. Filmcoat elite improves plant nutrient uptake, supports early plant development that aids in increasing root size, improve uniformity, and yield potential.

Filmcoat elite Carrot Overview

Key Benefits

  1. Larger seedlings with longer, more developed roots: Optimize access to moisture and nutrients
  2. Vigorous leaf canopy growth: Outcompete weeds and maximize photosynthesis
  3. Uniform root growth: Beneficial for maximizing harvest of root crops
  4. Increased yield potential: Benefit for the Growers

Field Trial Results

In collaboration with Growers, Plant Breeders and Seed Dealers, Filmcoat elite on Carrot has been trialled for three seasons in California and Mexico providing consistent trial results.

Improvement of overall yield

Improved Uniformity

Uniformity of root crops is particularly important to support effective harvesting. As illustrated left, the Filmcoat elite seed treatment resulted in improved carrot uniformity, compared to the control.

Filmcoat elite Jalapeno Overview


A commercial breeder who produces jalapeno pepper varieties that are popular amongst growers in North America and Mexico inquired with Germains Seed Technology to see if a treatment could be developed to improve the vigor and foliage growth of jalapeno plants. The treatments also needed to be compatible with crop protection products such as thiram. Their objective was to increase the plant’s foliar mass of a popular jalapeno variety to help protect the fruit from sun damage. They theorized that the dense canopy will protect the fruit from sunscald, therefore, improve the number of harvestable fruit and improve yield.


Sunscald may decrease harvestable yield,especially when harvesting the crop two or three times. To obtain more foliage and improve plant vigor for sun protection, the Filmcoat elite treatment was applied to jalapeno pepper seeds. Two independent commercial growers in Bakersfield, California, and Sinaloa, Mexico planted 100,000 seeds treated with Filmcoat elite thiram and 100,000 treated with thiram. The grower’s reported “that jalapeno seeds treated with Filmcoat elite and thiram produced more developed roots, stronger plant structure and more foliar weight and reduced the number of fruit damaged by sunscald.”

Key Benefits

  1. Vigorous leaf canopy growth: Protect fruit from sunscald, optimizing plants for multiple harvests
  2. Larger seedlings with increased foliage: Improve plants ability to withstand the transplant process
  3. Enhanced root development: Strengthen plants for growth in harsh growing conditions
  4. Increased yield potential: Benefit for the Growers

Field Trials

Compared with seed treated with only a filmcoat with Thiram, grower trials demonstrate that jalapenos treated with Filmcoat elite and Thiram develop more roots, stronger plant structure, vigorous plant canopy to protect fruit from sunscald, and a continued onset of flowers after first harvest. Filmcoat elite is compatible with emergis® priming, thiram, and other crop protection seed treatments.

Untreated vs. Treated filmcoat on jalapenos

Compared to seed treated with only thiram, trial data suggests that the jalapenos treated with Filmcoat elite combined with thiram developed more roots, stronger plant structure, heavier plant weight and more setting fruit. Trial data also reports that the crops experienced a continued on set of flowers after the first harvest.

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®.

ProFlo® is a heavy seed encrustment coating that increases the seed size and weight to help improve singulation when planted with a vacuum seeder. Proflo improves singulation during planting vs. planting raw seed while making the seed more visible in the soil. Unlike the traditional round pellet with a specific pellet size, encrustments maintain the seeds natural shape while adding bulk and weight to the seed so that it flows through vacuum planters with fewer skips and doubles.

New ProFlo® Seed Encrustment for Onions

Germains R&D team recently reformulated the conventional Proflo treatment for onions. The new formula enhanced the encrustment’s integrity, reduced dust off, and improved the accuracy of the final coated seed count per lb. to meet grower’s planter specifications.

Product Benefits:

  • Improved integrity for easy planting and singulation
  • Significant reduction in dust off
  • Elimination of buildup requirements for FarMore® applications
  • Finished desired seed count accuracy ranging from 55K to 95K +/- 5K seed per lb
  • Reduction in the number of doubles and skips

R&D Summary:

This product is designed to build to seed counts accuracy (±5000) by customer’s preference, and it was launched only after passing all tests conducted in our laboratory and field trials for a couple of years. ProFlo® passed plantability and pellet integrity test using air planter at variable disc speed and vacuum pressure. While performing air planter test, data was generated for seed flowability on doubles, skips, broken seed and dust off. Air planter handled the all seed treatments as per expectation without crumbling or damaging seed with minimal or no dust off. Seed count targets were met successfully with each build runs to target seed counts. Dust off was reduced by 80% over standard ProFlo®. Chemical loading (F300 and FI 500) tests remained within target range as per product’s rate of application recommendations. Field trials also met or exceeded expectation on seed emergence, total germination, and applicable transplant requirement.

ProPellet® elite seed pellet technology was specifically developed for celery.  ProPellet elite enhances the seeds performance in transplant production. ProPellet elite is a stacked seed technology that combines seed pelleting and health products that deliver stronger roots and vigour to improve the crop’s overall performance from transplant to harvest.

Key Benefits

  • Larger seedlings with increased foliage
  • Enhanced root development for easier transplant production
  • Improved vigour for better stand during transportation from greenhouse to the field
  • Increased yield potential

ProPellet® elite is an Innovative Solution to a Grower’s problem

ProPellet® Elite product development began with a single customer inquiry. A commercial celery grower was experiencing crop loss when transporting seedlings from the greenhouse to the field. The customer contacted Germains to see if a seed technology could be developed to improve celery seedling vigour and root mass for transplanting. Based on the grower’s circumstances, Germains’ Research and Development team customized an existing seed pellet by combining it with beneficial health products.

Used in either a greenhouse or in the field, seed encrustments are a minimal buildup of pelleting materials that help increase the seed’s weight and size. Seed encrustments also help improve singulation during automated planting and may include agrochemicals upon request. Seed encrustments reduce dropping doubles when planting which improves spacing between plants often reducing the need to thin the crop after planting when planting to stand.
