| Abstract/Contents: | "Infectious diseases account for substantial reductions in turfgrass quality each year. Extensive weed invasion, loss of grass cover, and poor appearance are conditions often associated with disease incidence. Most turfgrass diseases are caused by fungi. These are microscopic plants which lack chlorophyll and, therefore, the capacity to produce their own food through photosynthesis. Some fungi, fungal parasites, obtain their nutrition from living hosts; others called saprophytes, live off dead organic residues. Disease causing parasitic fungi are called pathogens... Control of turfgrass diseases can be achieved through timely applications of various fungicides, and by properly implementing certain cultural operations during establishment and afterwards. Cultural control may be achieved by: planting disease-resistant cultivars, following sound principles of site preparation during establishment, and managing an established turf through proper mowing, fertilisation, irrigation, and cultivation practices. Most diseases can be effectly controlled with timely applications of fungicides. Fungicides can either be applied prior to anticipated disease incidence (preventive) or following the appearance of disease symptoms (curative). Generally a preventive program is preferred for controlling diseases which are almost certain to occur under a specific set of environmental conditions. This may or may not require frequent spraying... Fungicides are either classed as contact or systemic. Contact fungicides (e.g: Dithane M45, Purasoil and Thiram) form a protective coating on turfgrass foliage and control susceptible fungi as they initiate growth... Systemic fungicides are able to penetrate the plant and are selectively toxic to processes unique to fungi. Two types of fungicides that are translocated within the plant are currently available: those that move only upward from the point of absorbtion, and those that move in both directions with the plant... Correct and timely use of the available fungicides and adherence to good cultural practices, will ensure minimum loss of quality and cover of turfgrass as a result of disease infection." |
