| Abstract/Contents: | "This study evaluated the influence of seaweed concentrate on bent (Agrostosis stolonifera cv. Penncross) subjected to nematode infection and low soil moisture. On 29 January, 1993, bent sod without soil was placed on expanded metal screens and transplanted to 19 litre containers filled with fumigated sandy loam soil inoculated with either Root-knot (Meloidogyne nassi) (RKN) or Lance (Hoplolaimus galeatus) nematodes. The grass then was grown in a greenhouse. Seaweed concentrate (SWC) was applied starting on 5 February, 1993 to supply different amounts sequentially as a soil drench or applied to leaves. Treatments were arranged in a randomised complete block design replicated three times. The grasses were irrigated for maximum plant vigor until 15 April, thereafter, water was added to the container to obtain field capacity (13%) every 14 days. The 4 litres haāā SWC (25%) drenched twice a month reduced yellowing, thinning, wilting and improved leaf water status and clipping yields of the infected turf. Rooting improvement of more than 40% was associated with this treatment applied to both nematode-infected bents. This increase was significant for the RKN-infected bent. Nematode populations did not differ between the differently treated grasses, indicating that SWC treatment enhanced bent growth rather than reducing the nematodes." |
