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 would protect the fruit from sunscald and 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: Provide benefit for 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, a more 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 onset of flowers after the first harvest.

Seed Disinfection Treatment for Carrots

Carrot Overview

Bacterial leaf blight, otherwise known as Xanthomonas campestris pv. carotae, is a concern to carrot seed producers and growers in many regions of the world. The bacterium can survive on or in a carrot seed, spreading via the seed’s movement through the supply chain into the field. Planting healthy, clean seed is an essential first step for effectively managing bacterial leaf blight.

Carrot Trial Data

Tested on five carrot varieties, independent lab results conclude gopure is an effective solution for removing Xanthomonas from carrot seed without impacting germination or shelf life.

Seed Disinfection Treatment plus Crop Protection for Spinach

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 is a seed disinfection treatment that also has the additional benefit of Rancona® for 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 seed’s 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 count 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 an air planter at variable disc speed and vacuum pressure. While performing the air planter test, data was generated for seed flowability on doubles, skips, broken seed and dust-off. The 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.

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.
