Fusarium Blight (Syndrome) is soil borne group of fungi that cause a donut shaped ring of dead grass with a green center. As the Disease progresses
these rings overlap each other, making the lawn appear blotchy, and the rings less visible. The dead grass in the rings causes a depression in the area
CONTROL Control is difficult at best. Fusarium is most active during Hot weather, when the turf grass is under the most stress. Therefore anything one can do to
reduce this stress is helpful. Watering on a regular basis - frequently, (Daily 2x at 1/2 each time) is one way to reduce the temperature and stress in the
lawn area. Thatch lawns are also more susceptible so core aeration is recommended for the next few years to help reduce the level of thatch present.
Mowing as high as possible 2-3" will also reduce the stress the lawn is under and help the lawn with its fight.
Chemical Controls are available but are very expensive, and short lived (1-2 wks) so Earth Care does not promote their usage as the results tend to be
less than desirable.
Rust is disease that attacks bluegrass and Rye grass. The orange spores from the diseased plant cause the lawn to have a orange-ish appearance and ones feet and mower can become covered in a orange-ish powder. Rust is not considered a major problem as it is easy to correct and rarely causes severe damage to the Turf. If no control measures are used this disease will slowly thin the lawn over time,and will be a re-occurring event when conditions are right.
Rust is easily controlled by applying a Fertilizer high in Nitrogen. Rust tends to be prevalent in lawn areas that are relatively new and more prone to nutrient deficiency. Once this deficiency of Nitrogen has been corrected the Grass tends to grow faster than the disease and the organism responsible is mowed away before it can reproduce.
