Algae

Other common names:

Not applicable.

 

Description:

Algae is a non-infective disease; however it is unaesthetic and has the ability to limit turfgrass development and water infiltration. Algal growth is often found in damp shaded areas and or where drainage is limited/poor. Soil compaction can also exacerbate the issue.

 

Susceptible Turf:

Warm-and cool-season turf grass varieties.

 

Symptoms:

Green algal spores forming a layer or crust on the soil surface.

 

Control options:

  • Pesticides: See available tabs below for registered products. Use as per label instructions.
  • Integrated Pest Management (IPM): Use a combination of approaches listed on this page.
  • Cultural: Increase airflow and reduction of water. Avoid over application or unnecessary Phosphorous fertiliser. If algae is present, it may prove necessary to undertake soil or leaf tissue nutritional testing to determine if surplus Phosphorous is a problem.
  • Mechanical: Aeration, topdressing and/or physical disturbance of the algae spores and soil surface.
