“…Among them seaweeds are considered as valuable source of unique polysaccharide elissitors and perspective biostimulants, which are not found in terrestrial plants [1]. Seaweeds contain a wide spectrum of biologically active substances, oils, lipids, fatty acids, microelements, vitamins, pigments and hormones due to they exhibit positive effect on the plant growth, development and yield [2][3][4][5][6]; activate the formation of different metabolites, particularly, phenolic compounds playing one of the cue role in plant defense, and, therefore, increase plant resistance to various stress factors, including abiotic stress and diseases caused by viral, fungal, bacterial infections and plant pests [1,4,[7][8][9][10][11][12][13].…”

The study was aimed on the assessment of extracts from two arctic brown seaweeds Ascophyllum nodosum and Laminaria digitata as biological nematicides against phytoparasitic nematodes. Potato cyst-forming nematode Globodera rostochiensis Woll. was used as test organism. Seaweed extracts were got from Arkhangelsk Seaweed Factory LLC. Extracts of A. nodosum and L. digitata have been experimentally shown to have nematicidal properties against the dangerous potato pest G. rostochiensis. The addition of seaweed extracts to potato root diffusates slowed down nematode juvenile hatching process, affected the contents of cysts, reducing the reproductive potential of the plant-parasitic nematode. Research highlights the perspectives of using seaweed extracts in nematode-infested fields for control crop pests.

This review presents a comprehensive and systematic study of the field of plant biostimulants and considers the fundamental and innovative principles underlying this technology. The elucidation of the biological basis of biostimulant function is a prerequisite for the development of science-based biostimulant industry and sound regulations governing these compounds. The task of defining the biological basis of biostimulants as a class of compounds, however, is made more complex by the diverse sources of biostimulants present in the market, which include bacteria, fungi, seaweeds, higher plants, animals and humate-containing raw materials, and the wide diversity of industrial processes utilized in their preparation. To distinguish biostimulants from the existing legislative product categories we propose the following definition of a biostimulant as “a formulated product of biological origin that improves plant productivity as a consequence of the novel or emergent properties of the complex of constituents, and not as a sole consequence of the presence of known essential plant nutrients, plant growth regulators, or plant protective compounds.” The definition provided here is important as it emphasizes the principle that biological function can be positively modulated through application of molecules, or mixtures of molecules, for which an explicit mode of action has not been defined. Given the difficulty in determining a “mode of action” for a biostimulant, and recognizing the need for the market in biostimulants to attain legitimacy, we suggest that the focus of biostimulant research and validation should be upon proof of efficacy and safety and the determination of a broad mechanism of action, without a requirement for the determination of a specific mode of action. While there is a clear commercial imperative to rationalize biostimulants as a discrete class of products, there is also a compelling biological case for the science-based development of, and experimentation with biostimulants in the expectation that this may lead to the identification of novel biological molecules and phenomenon, pathways and processes, that would not have been discovered if the category of biostimulants did not exist, or was not considered legitimate.
