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.
