(Also known as: brown seaweed extract; knotted wrack; marine algae extract; ANE) |
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.

An extract from a marine brown seaweed demonstrated to act as a biostimulant and in particular it increases root colonisation and abiotic stress tolerance |

Ascophillum nodosum extract has been extensively studied for its potential as a biostimulant and shown to offer significant benefits for plant growth, yield, and quality, the alleviation of biotic and abiotic stresses in plants, and their effects on the interactions of plant root systems and microbes. Studies with rapeseed, tomato, carrot, cucumber, soybean and cereals showed that the application of A. nodosum extract significantly improved the germination rate, increased the growth of lateral roots, enhanced water and nutrient use efficiencies, increased antioxidant activity, increased phenolic and flavonoid contents, increased chlorophyll and nutrient contents, alleviated the effects of abiotic and biotic stresses in different crop plants, and even improved the postharvest quality of different fruits. |

As a biostimulant the mode of action is not fully understood. It is driven by the extracts rich bioactive substance composition (phenolic and antioxidant compounds) which improve rooting morphology and nutrition. It has also been shown to regulate expression of stress-responsive genes. |
