The effect of a liquid seaweed extract from Ascophyllum nodosum (Fucales, Phaeophyta) on the two-spotted red spider mite Tetranychus urticae
Tóm tắt
This paper presents evidence from an initial trial in favor of claims that the liquid seaweed extract of Ascophyllum nodosum, marketed in the UK as ‘Maxicrop’, can reduce numbers of the two-spotted red spider mite Tetranychus urticae on crop plants. Seven applications of Maxicrop Triple over 20 days significantly suppressed the population build-up of two-spotted red spider mites on treated strawberry plants (Fragaria sp. var. Redgauntlet) raised under high polythene tunnels as compared to untreated controls.
