How to kill moss, scientifically

I'm on an email list for Grad students at both Vic and Massey uni's, which means I get a constant flow of email about what is going on at both places. These range from "lost USB found in the tearoom" to "Guest academic speaking about bla bla bla"

Anyway, I've just got an email from Vic which I think is a real classic!

Normal people who want to get rid of moss somewhere public would maybe say something along the lines of:

"There is moss in the glasshouse, so I'm going to spray it. Please keep out for a day or two. Thanks"
(Moss & Lichen on Mt Arthur, Nelson)

However, in the scientific world, it sounds like this:

"It is my intention to try to deal with the problem of the slippery glasshouse floor later this afternoon. I am going to water the floors with Watkins Algae and Moss killer. This contains benzalkonium chloride and copper sulphate. I want this left undisturbed over the weekend so I can monitor the effect. Please do not go into the glasshouse after 3pm today until Tuesday afternoon 2nd June Thanks."

NO JOKE, that is the exact wording in the email!!

Scientists are... special :P
