Fast Roots. Faster Bulbs.
Real Results.


Stimplex® is a unique biostimulant that fuels the growth and development of healthy plants. Stimplex works at a cellular level by improving the production of naturally occurring plant hormones that stimulate stress resistance, improve root growth and maximize nutrient uptake. This all leads to enhanced yield for a greater return on investment.

Benefits to Onions

  • Enhances Rooting
  • Increases Nutrient Uptake
  • Mitigates Environmental Stresses
  • Improves Overall Yield

Stimplex Improves Yield and Quality

Stimplex gives your crop strong early growth, good nutrition and the ability to tolerate what Mother Nature dishes out for your best yields ever! In addition, Stimplex works at a cellular level by improving the nutritional status of your crop leading to big yields.

Onion Yield

Stimplex improved onion yields by 5,900 pounds per acre averaging a 15% yield increase.

How Does Stimplex Benefit Onions?

Improves Rooting:

A strong root system sets the stage for your best yields – and Stimplex offers your onions the best opportunity for excellence! Stimplex starts your onions off with a strong root system – and in turn robust bulbing – even in challenging early spring growing conditions. Stimplex contains unique bioactive compounds such as fucose-rich sulphated polysaccharides and alginates which stimulate root initiation and enhance the formation of small absorptive roots. This leads to improved plant establishment and uptake of water and nutrients.

Improves Nutrient Uptake:

Stimplex supercharges your nutritional program by improving onion crops’ nutrient uptake. When you apply Stimplex as part of your regular application program, you’re putting nutrients on the fast track and ensuring your plants get the most out of every ounce of fertilizer.

Stimplex contains natural complexing sugars which bind to micronutrients, thereby improving the bioavailability and transport of nutrients within the plant.

Mitigates Environmental Stresses:

Don’t let stress steal your yield! Mid-season applications of Stimplex prime your onion crop to defend against numerous stresses to prevent doubles, pest damage and blemishes. Stimplex helps plants keep energy focused on reaching their maximum yield potential. With its numerous bioactive compounds such as mannitol, unique polysaccharides and betaines, Stimplex improves a plant’s tolerance to a variety of stressful growing conditions including drought, chill, heat and salinity stress.

Onion Yield

Stimplex improved onion yields by 3,200 pounds per acre, averaging an 8% increase.

Increases Yield and Quality:

Optimize your onion yields when you drive maximum root growth, nutrition and stress management with Stimplex. You’ll see the results in faster bulb establishment, improved nutrition and reduced crop stresses.

Rates and Timings

Apply 8 oz/acre in a band at planting or emergence, followed by applications at 2 qt/acre made every 2-3 weeks (Soil or Foliar).

Stimplex mixes well with nutrients and other agricultural products.
