Alternative treatments for turf disease

摘要

Fungicides are a critical tool for controlling fungus-incited diseases on amenity turf, as well as in commercial and residential plantings of selected herbaceous plants, shrubs and small trees. While the heaviest fungicide use occurs on intensively managed turf such as golf course greens, fungicides are also used on home lawns and, to a lesser extent, on greenhouse crops and woody plants like roses. Because these fungicides work to quickly remove disease and recover turf and ornamentals, grounds managers are often tempted to repeatedly use "the same ones that worked last time." However, over-reliance on one or several fungicides, particularly those that attack a single declining sensitivity or resistance in some plant pathogenic fungi. As expected,golf courses have been the focal point of nearly all of the resistance-related control failures reported on amenity turf and ornamentals.
