Motorised sprayers at my club often leave little bits of foam (maybe 3cm x 15cm) on the green.

I presume these are not loose impediments, and therefore the player must putt through them – even though they most definitely can affect the putt?

These are to mark the line for the sprayer, so he knows where he has sprayed. I shouldn’t image they would effect the line of a putt, but I would think these would be the same as grass clippings left for later removal, they can be removed, I mean, they could be blown away by blowing on them…

Dec 25/6: In equity (Rule 1-4), saliva may be treated as either an abnormal ground condition (Rule 25-1) or a loose impediment (Rule 23-1), at the option of the player.

I’d imagine foam would have the same status.

I’m trying to imagine how there could be saliva on the green.

Oh, I get it. Some great pig (male, no doubt) does a huge slag – nice.

Cheers, Peter.

I would say that it should be treated as casual water, but there’s no definite answer for this one.

It’s just water in another shape really, and if we treat foam as ice or snow, the player gets the same relief as he would in the Decision mentioned by @publish. That would seem fair.

I didnt think snow or ice were given casual water or loose impediment status , hail yes

Definition of Casual Water
“Casual water” is any temporary accumulation of water on the course that is not in a water hazard and is visible before or after the player takes his stance. Snow and natural ice, other than frost, are either casual water or loose impediments, at the option of the player. Manufactured ice is an obstruction. Dew and frost are not casual water.
