never heard of it. So being a curious soul I have search the internet and can find it but it doesn't say how it works other than it is a physical method, or what's its ingredients are.

Haven't used it myself but there was a piece by Jane Perrone in the Guardian a couple of weeks back.

The comments section is worth looking at, the gist was why risk harming good insects to combat mildew? If I remember rightly

Seaburn I think there may be a link in the comments under the article to check ingredients. I'm fairly sure that under EU legislation there's a requirement to publish an ingredients list for all consumer products

Not tried it but can vouch for the spectacular results of volcanic rock dust...

I gone on their own website and it just gave generic responses. I wont be using it so I may not check. ;o)

I think they're called Consumer Safety Data Sheets
Here's the link:

They are the ones I looked at and it didn't name specific chemicals.

I trust your judgement Seaburn. Lauryl sulphate was included amongst other things? That's a fairly specific chemical? Though I am aware that dihydrogen monoxide can be deadly

Sounds like money grabbing gimmicky things. We have all kinds of gurus pushing all kinds of gadgets and things with outrageous claims. Most of them are cash grabs that prey on the gullible. - here today, gone tomorrow! Since you cast it aside with no regrets, I'd probably do the same.

Darren dihydrogen monoxide is the chemical name for water....(perhaps you are thinking of carbon monoxide?) Lauryl sulphate is an ingredient of detergents which lower surface tension ( so the stuff you spray on doesn't run off -
So it looks as though they are trying to blind us with science.

Sorry Stera, I was just joking but trying to make a point about 'chemicals'. A lot of people die from too much water? But the public understanding of risks with 'chemicals' is really low? I think there's lauryl sulphate in my toothpaste

You can certainly die from too much water if you keep your head under it for too long...
You are so right -trouble these days is Chemicals are bad according to popular talk - but we and our food are made of chemicals after all...and so is everything else come to think of it!

Exactly, you can die from drinking too much water because it throws out your chemical balance. LD50 for water is about 6 litres, though LD50 has fallen out of favour as a measure these days

Lauryl sulphate is commonly called a wetting agent and in the FAQ it says no need to use a wetting agent due to the composition of the product.

I suspect due to its use as a degreaser in the cleaning industry [its in a bike cleaning product my hubby uses] it works the same way that we suggest people use a soap spray to kill off aphids.

people at least are being conscious of the need to reduce the more harmful chemicals they are adding to the environment when they use this product. I wonder if the garden 'expert' was promoting the product for the company.

I must have looked at a different bit on the web page Darren as I didn't find any chemicals listed.

I think it's the product safety data sheet that's where the info is. Just tried it for Anadin ultra & it worked so I assume it's available for a wide range of products Seaburn
