(Not known by any other names) |
The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement. These hazard alerts do not take account of usage patterns or exposure, thus do not represent risk.

An extract from the leaves, stems and roots of the Yucca schidigera plant comprised of natural plant steroidal saponins which has some biostimulant, fungicidal and bactericidal activity |

|
Despite the commercial use of yucca extract as a plant biostimulant limited data appears to be available regarding the efficacy of it as a biostimulant. However, it has been shown to promote germination and early vigour under drought/osmotic and salt stress induced either by sodium chloride or lithium chloride. |

Mode of action as a biostimulant is unclear. However, the extract promotes mobility of nutrients and water across plant and soil surfaces providing multiple plant benefits. For animal health, it is considered a nutraceutical, with functions that include: digestive enhancer, anti-inflammatory agent and odor control additive. |

Data for specific plant extracts is scarce. However, from publicly available data the carbon footprint of plant oils has been estimated at between 1.0 and 4.0 kg CO₂e per kg of product. This depends on the plant extract content, agricultural practices and processing methods used. |
