Top-dressing formulated with sand:organic matter mixtures were applied to perennial ryegrass ('Palmer') to evaluate their effectiveness in suppressing Red Thread (Laetisaria fuciformis ). A disease-suppressive microflora was introduced into topdressings as complex microbial mixtures found in composted organic wastes and organic fertilizers composed of various plant and animal meals. Topdressing formulations consisted of 70% fine sand and 30% organic component (v:v) and were applied at the rate of 400 cm3/0.8m2 plot. One application was made and plots evaluated for disease severity approximately one month later. Cutting height was maintained at 1.5 inches throughout the experimental period. 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 (data not shown)."
