The fungicide products mentioned in this section are registered for use on
turfgrass in California, but many have not been evaluated by the University of
California for their effectiveness in controlling turfgrass diseases. The
fungicides are listed alphabetically in the treatment tables and not
necessarily in the order of effectiveness. In general, use fungicides only on
golf and bowling greens and other high maintenance turfgrasses. For best
results, use fungicides preventively or when the disease is first visible.
Accurate identification of a disease is critical to choosing the best
fungicide. Read and follow fungicide label recommendations carefully for rate
recommendations, which usually vary based on the severity of the disease and
whether the treatment is preventive or curative.
Turfgrass areas such as landscape areas and parks only rarely require fungicide
applications. Good cultural practices including proper turf species selection,
appropriate use of fertilizer and irrigation will prevent serious damage in
most turfgrass areas.
