Abstract

Nutrition and disease control are two essential areas of fine turf management. The application of phosphite (H3PO3) to turf surfaces has been suggested as a means to reduce susceptibility to fungal diseases and to improve turf quality. The aim of this study was to measure changes in quality, growth and disease resistance of an Agrostis stolonifera L. sward following applications of phosphite.

Agrostis stolonifera L. trial plots were established in a controlled environment greenhouse and on Curragh Golf Course, Ireland. Three phosphite treatments were applied: 0.35g/m2, 0.525g/m2, 0.70g/m2 and compared with equivalent rates of phosphate and control plots. Growth, turf quality and Microdochium patch (Microdochium nivale) occurrence were assessed monthly for all plots over one growing season. No significant differences in growth between phosphite and phosphate treated plots was recorded. Phosphite treated plots had significantly greater turf quality (p
