New lawn problems

I have recently layed a new lawn 4 weeks ago and things were going great until this week where I’ve spotted white cotton like spores starting to show on certain areas of the lawn. I’m guessing this is the start of fusarium after researching the web. I’ve purchased some lawn control disease by Bayer in hope that this will help cure the problem. I have not used the application yet asi would like to know if this is the correct procedure especially with the lawn being so new and only recently laid.
any help on what to do would be much appreciated.

    It would help if you had a photo or 2 so that the lawn specialists amongst us can give a diagnosis.
    It may just be some random fungus that's best ignored. Not my area of experience I'm afraid.
    Hope your lawn is ok

  • I'd wait until you get a lawn specialist on here, because even if it is fusarium I suspect you may damage a very new lawn by applying chemical treatments before it has properly "bedded in".  I'd stress I don't actually know if that's true - it's just a "gut feeling"...

  • Here are photos as requested. This is happening all over my garden. Not just in one certain area

    @glasgowdan might be able to help - I have tagged him to see if he can. 
  • My advice would be not to apply anything just now other than an autumn/winter treatment with iron and perhaps organic micronutrients. 4 week old turf won't be fully rooted and is adjusting to it's new conditions. Once the grass plants are growing strongly they will likely overcome this and other fungal visitors no problem.

    thanks for your advice. If the fungus takes over the lawn tho, what do you recommend? It’s in patches at the minute but scattered around the lawn. The lawn isn’t rooted in certain areas yet as you can still peel certain turves back. 
  • I don't think you need to worry about it taking over the lawn to be honest. Treatments get less effective as the weather gets colder, whilst fungus fades away at the same time
