Turfgrass Biostimulant/Adjuvant Compositions




Agricultural adjuvants are commonly used in conjunction with pesticides to enhance their efficacy. An adjuvant does not actively fight fungus or pests, but it improves the ability of a fungicide to prevent or cure disease.

One popular adjuvant used in turfgrass applications is made of mineral oil, combined with a surfactant, emulsifier and dye.  There are a few concerns with this particular adjuvant, specifically its effect on heat tolerance and adverse environmental impacts. In high heat, this adjuvant can kill the turf, resulting in a complete loss for the season, at a minimum. Also, mineral oil is marked by poor biodegradation, leading to harmful effects on the environment.


Description of Technology


This technology is an inexpensive and naturally-occurring adjuvant that increases the effectiveness of fertilizer and fungicide. Fungicide and fertilizer application rates may be greatly reduced when mixed with this natural product.  Turf density and growth are also improved through use of this adjuvant.

Unlike the prior art adjuvant, this technology does not have adverse effects on heat tolerance, and does not include mineral oil.


Key Benefits

  • Reduction in Fertilizer and Fungicide Application: To achieve the same growth rate and turf density, 50% less fertilizer and fungicide can be applied when using this adjuvant.
  • Dew Suppression: This adjuvant deters water droplets from beading on grass blades, therefore reducing the drying time after dew formation.
  • Alleviates Desiccation:  The harmful effects of winter and early spring desiccation are diminished when this adjuvant is used.  In turn, this promotes a healthier turf at the start of the next growing season.
  • Natural: The adjuvant is a plant extract, which improves biodegradation and lowers environmental impact when compared to a similar, petroleum-based adjuvant currently on the market.
