摘要：

Seaweed concentrate (SWC), prepared from Ecklonia maxima, when applied as a soil drench to tomato seedlings, significantly increased plant growth and reduced infestation by Meloidogyne incognita. Foliar applied SWC had little effect on plant growth and increased nematode galling. Ashing SWC reduced the suppressive effect on nematode infestation. In an in vitro experiment, SWC lessened infestation of root-knot nematodes on excised roots of a susceptible cultivar of tomato. Application of the same concentrations of SWC to a nematode-resistant cultivar increased the number of egg masses.
