The Non-Ionic Surfactant, Spreader, Activator

Analysis: 50% Extract of Yucca Schidigera

What Is It?

  • CFIA-registered supplement: Reg. # 2018085A, Fertilizers Act.
  • It is a natural extract of Yucca schidigera, a plant that grows in some of the harshest environments.
  • Yucca is a rich source of steroidal saponins as well as other stress-alleviating compounds and antioxidants.
  • Saponins are natural surfactants and wetting agents.
  • When added to the spray tank, saponins from the Yucca extracts reduce the surface tension, hence facilitating the spread of fertilizer solution onto the entire leaf.
  • When applied onto the soil with liquid starters, Yucca extract acts as a wetting agent reducing the formation of dry spots or water channels. This improves nutrients and water uptake in the root zone.

When & Why Use It?

  • The product is recommended on all crops including field, horticultural and vegetable crops as well as fruit trees, turf and ornamentals.
  • Include low doses with all sprays or soil applied fertilizers.
  • Use with fertilizers to enhance efficacy and improve hydration and coverage.
  • Saponins are known for their stimulatory activity of growth and development as well as their protective effect against biotic and abiotic stresses.

What to Expect?

  • Better spread and improved coverage of the foliage.
  • Improved water use efficiency (WUE).
  • Protection against dehydration, excess UV and heat.
Figure 1. Effect of saponins from the Yucca extract on the breakage of surface tension as compared to other non-ionic surfactants (Source: Stanimirova et al. 2011).
Active ingredients may be trapped in spray deposits; Strong adhesion limits contact area; Little spray droplets movement through cuticular pores; Limited translocation due to restricted uptake
Figure 2. Effect of the addition of Yucca extract on the improvement of the contact angle and wetting of the leaves.
Non-wetting, contact angle: 180 degreed; a large, round liquid drop
Wetting, Contact angle: less than 90 degrees; a flatter liquid drop
Perfect wetting, Contact angle: 0 degrees; a competely flattened liquid drop

Application Guidelines

  • Yucca can be mixed with commonly used liquid fertilizers intended for in-furrow or foliar.
  • Include with all foliar sprays of fertilizers and/or pesticides.
  • Apply with enough water
