Chemical Trials for Snow Mould Disease Control


TurfDis14T. Hsiang and S. Cook, University of Guelph - Guelph, Ontario, Canada Department on Environmental Biology, 1992-1993

Twenty-seven chemical and control treatments were evaluated on a 15- year-old sward of creeping bentgrass in Southern Ontario during December 1992 to April 1993.

Biological Control of Red Thread on Perennial Ryegrass


TurfDis13Eric B. Nelson and Cheryl Craft , Department of Plant Pathology , Cornell University, Ithaca NY, 1990

Of all the treatments evaluated, only Sustane (5-2-4) (poultry litter compost) was effective in suppressing red thread. A high level of suppression was observed at least 27 days after application. Diameter of infection centers was also reduced as compared with untreated plots and other compost treatments.

Necrotic Ring Spot Fungicide Studies


TurfDis12Hancock Research Center, East Lansing, MI, 1994

All fungicide and fertilizer treatments gave statistically significant reductions in disease, compared to the fertilized control. In this study, once again, the 1.b. N/1000 ft2 plots of Sustane, IBDU and Ringer Turf Restore exhibited superior density and overall turf quality.

Composted and Organic Fertilizers on Turf and Their Value in Reducing the Incidence of Turf Diseases and Insect Pests


TurfDis11NOEL JACKSON, PROFESSOR , DEPT. OF PLANT SCIENCES THE UNIVERSITY OF RHODE ISLAND, 1988

Six composts derived from different organic sources, a dried sewage sludge (Milorganite), a commercially available organic amendment derived from sewage sludge for turfuse (Lawn Restore) and the fertilizer urea, were included in an expanded version of the 1988 trial at the URI Experiment Station Turfgrass Research Farm.

Effect of Bio-organic and Slow-Release Fertilizers on Necrotic Ring spot of Kentucky Bluegrass


TurfDis10Brad Melvin, Joe M. Vargas, Jr., Ron Detweiler, Trevor D’Souza and Lori Lick, Department of Botany and Plant Pathology, Michigan State University, East Lansing, MI, 1990

Bioorganic turf amendments were examined for their influence on microbe populations, management of Necrotic Ring Spot (Leptosphaeria korrae) and thatch control in each of three different irrigation regimes.

Suppression of Dollar Spot on Creeping Bentgrass and Annual Bluegrass Turf with Compost Amended Topdressings


TurfDis5ERIC B. NELSON, Assistant Professor, and CHERYL M. CRAFT, Research Support Specialist II, Department of Plant Pathology, New York State College of Agriculture and Life Sciences, Cornell University, 1992

Topdressings formulated with mixtures of sand and various composts or organic fertilizers (70:30, v/v) were applied to putting greens of creeping Bentgrass and annual bluegrass and evaluated for their ability to suppress dollar spot disease development.

Effect of Sustane Natural Fertilizer on Diseases of Cool-season Turfgrasses


TurfDis8Eric Nelson, Ph.D. Cornell University, Ithaca New York, 1991-1996

Turf management with natural organic fertilizers and the suppressiveness of compost amendments to turfgrass disease. 

Of all the natural organic materials commonly applied to turfgrasses, composted amendments have been among the most consistently effective in reducing the severity of turfgrass diseases. Composted turkey litter (Suståne) and other poultry manure composts are consistently more suppressive to a wider range of diseases than are brewery and municipal biosolids in field experiments.
