In this article, we will be looking at turf disease and how we can bring resolutions to those problems which can turn a nice healthy manicured lawn into a lawn that’s stressed and dying.
Apart from the maintenance practices that are carried out St Augustine grass also faces the issue of dealing with diseases such as take all root rot, grey leaf spot and brown patch disease, if these problems are not correctly identified and dealt with that once beautiful law will become an eyesore.
So then we will first be looking at take- all root rot disease, The fungus that is responsible attacks the roots and because of this the turf is not able to take up water and nutrients through the normal process. When this happens the turf begins to decline. To learn more about St Augustine grass clink this link. Grass-type.
Signs of take- all root rot
Signs are large irregular patches in the turf that turn yellow followed by these areas becoming bare spots where turf once was, the fungus that causes this disease is most active during summer and early fall when the temperature is high.
Another sign to look for is turf has short rotted roots that cause the grass stolons to be easily pulled up from the ground.
Signs of Grey leaf spot
Grey leaf spot develops under moist conditions, signs are an off green and brown colour, moist area in the lawn. The infected areas begin to enlarge because of this fungus and the grass also has purple margins, the affected area may also take on a greyish appearance that is caused by this fungus.
The fungus that causes this disease is most active during warm weather that is accompanied by high humidity, also at this point fertilizers that are nitrogen base should not be used as this helps to increase turfs vulnerability against this fungus.
Use fungicides to treat turf area, water early in the morning so that turf can dry. Only use fertilizers that are low in nitrogen.
Signs of Brown patch
Brown patch is another disease of St Augustine grass that is caused by a fungus, areas that are affected by this turf turns yellow and begins to wilt as the disease sets in, these areas also turns brown-red. When turf that is affected is pulled on it comes up very easily
This is because rot has already set in, action should be taken immediately in order for turf to recover.
Apply fungicides making sure to follow label the direction, also do not use fertilizers that are nitrogen base only but use a balanced fertilizer that will help the grass to recover much quickly.
Bahiagrass is a turf that can grow into a beautiful lawn once it is maintained properly, however, the major disease problem of bahiagrass is dollar spot.
Signs of dollar spot
