Maintaining the Quality of Your Lawn
Red Thread Disease
Lawns need treatment all year round.
Weeds, moss and diseases are a continuous threat in our largely cool,
What is Red Thread?
Red thread is a fungal disease which attacks the grass plant when conditions suit. It will show up as pink / red patches in your lawn while the disease is active. When the attack passes it will leave straw coloured, disfigured patches of grass leaves behind. The disease does not impact the root of the plant, thereby soon recovers. Dis-figuration to the turf is temporary, but these areas may be unsightly for a time.
How do we treat Red Thread?
Our lawn survey considers a range of chemical, physical and biological factors.
We advise our customers individually when we survey their lawn.
Our treatments for this disease include:
Fungicides suppress turf disease.
This is important on sports surfaces ahead of a big fixture where a large budget is in place with the surface tended to almost around the clock.
For lawns it is not something that we recommend, and certainly for red thread. As we know, red thread will reoccur should the conditions present themselves. Following an expensive fungicide application, the disease could return with greater vengeance 6 weeks later. Although some lawn care companies will offer this option - in our opinion it's not worth our time or your money.
The option of masking the disease is the viable short term option until the weather dries up a little. A few ideas:
A nitrogen based fertiliser will help the damaged areas to 'grow out'. The fertiliser will give a colour boost and improve growth. Remember, a drip feed of food is best.
A potassium based fertiliser, maybe with added calcium will improve disease tolerance. However, it's unlikely that your lawn is suffering from a adeficiency.
Magnesium and iron will improve the colour of the lawn. Consider a liquid application for quick results over a granular. If applying iron through the winter also, consider the level of iron that is now going to be applied to the lawn - this may impact soil pH. Iron works to dehydrate moss, so be cautious in it's application through summer and it will do the same to grass at a given rate..
Why do you need to treat Red Thread
Red thread will rarely kill the grass completely, the patches will recover with appropriate remedial action.
Spread of the disease can occur by airborne or waterborne spores, or on contaminated tools or shoes. Prolonged leaf wetness is required for infection, so red thread is most likely to be a problem in wet summers and during heavy dews in autumn.
The best way to avoid red thread disease is to create conditions that the fungus doesn’t like. You are unable to control temperature, but you can make sure that your grass drains as well as possible.
Trim trees and bushes to make sure there is plenty of ventilation to help evaporate surface moisture. We recommend to Scarify and aerate your lawn at least once a year to improve drainage. Scarifying also removes the thatch layer which often harbours fungal spores.
Remember to feed your lawn regularly all year round. Use the correct formulation for the season and be sure to follow the manufacturer’s instructions carefully.
