Weird White Fungus on Office Plants Help!!!

For a couple of days now I've noticed the plants in my office develop this whit fungus, I was wondering if anyone could identify it and come up with a solution on how to treat it?

Thanks

 

Difficult to say for sure but it looks like some kind of mildew.

Any fungicide spray would probably cure it, but its a sign growing conditions are not as good as they could be.

Office plants usually have put up with all kinds of neglect.

 

try this: Provado ultimate bug killer ... (not sure if it's the right stuff to use, but if no one else gives advice on this thread, may be worth a try as it's pretty cheap)

Provado Ultimate Bug Killer 1 litre Ready to Use | Systemic Insecticide in handy spray gun | PlantMeNow.co.uk

 

If it's mildew the Provado won't help though.
Use a fungicide instead, that should.

I agree though, houseplants are woefully treated :(
Give them some fresh air in the warm months and plenty of circulating air generally.
