How much is Glyphosate

[penfold]

if you really want to open a can of worms just mention FEPA.

Dean bayer cropscience do a product called timbrel which can be used on brambles. Its active ingredient is a triclopyr acid equivalent. A 5 litre pack covers 6250m2-20,500m2. there are two fairly local stockists Gem Gardening or Sherriff Amenity

Ammonium sulphamate is probably better on woody stuff like brambles but its not for sale to the public anymore, maybe still ok to liscenced trade. Its what I use for stump killing.

 

" Ammonium sulphamate has now been completely withdrawn from sale as part of the periodic EC Review Programme. Products containing the chemical can be stored and used until 22nd May 2008. Beyond this date it will be illegal to store or sell any product containing this chemical."

 

AIE - TrunkLine - Autumn Colours

 

I think it has been withdrawn because wild birds can be killed if they eat the crystals.

 

The above link gives advice on alternatives.

£128 today for 20L of glyfos supreme

[treediver]

That one's gone too even for stump killing.

 

You can still buy ammonium sulphamate legally.... as a soil improver/compost accelerator. Just remember its harmful to plants

Dare i say COSHH, or will that open a can of worms?

 

no he won.t know what that means

probably thinks your about to hit him

£60.74 inc vat i paid, june 2007, im pretty certain that was 20 litres.

 

just dont buy roundup as you will get ripped off big time for that.

 

Now that is cheap.

 

I paid a bout £60 for 5 litres of Glyphos(sp*) although iirc it had a time rate thingy of 3 hours before it rained but I think that has gone up to 6 for some reason (very important in this part of the world).

Have been following this thread with some interest, as a member of NOROSO ( NAtional Register of Sprayer Operators). I will try and put every thing into perspective, as some of the posts are incorrect and some what mis leading.

Glyphosphate is a non selective weedkiller, this means that whatever you spray it onto will be effected. It consists of Glyphosphate which is the active ingredient,. There are a number of products on the market, but the most commom are

1. Gallop: contains 360 grams Glyphoshate per Litre

2. Glyphos Supreme : contains 450 grams per litre

Application rates are generally about 1.25 litres per hectare, costs are Gallop £95.00 per 20lt, Glyphos Supreme £130.00 per 20 litres, but these will vary depending on where you source it. Best place is to locate your local agricultural merchants and ask for prices, all these are plus VAT.

Glyphoshate hasn't changed it has always contained isopropaline salt, but some products have pottasium salt in them, that's probably where you are getting confused.

The reason why it doesn't last long in the soil is that it is a contact herbicide only, this means that it kills what it comes into contact with, it is not residual, meaning that it is contained actively working in the soil. Glysphoshate is translocating so once the active ingredient is absorbed into the leaf it moves up and down in the plant thus killing the green tissue and root system as well.

In fact when Glyphoshate touches the soil it becomes locked up in the particles and becomes neutralised i.e. inactive.

Paraquat is Gramoxone, it is a poison with no known antidote, it is no longer available.

If you want to treat brambles, the most effective product is Grazon 90, this contains Triclopyr, which is a pyridine Carboxylic acid.

Hope this is of some help to you all.

and yes we do have to keep all our records, and dispose of the cans correctly as they are classed as hazardous waste.

The longer it has to dry on the leaf before rain the better, the general time is 3 hours drying for the products with the higher active ingredient, and 6 hours for the products with less active ingredient.

Also don't spray it onto a wet leaf as depending on what water volumnes you are using you will get run off, i. e. the chemical comes into contact with the water on the leaf instead of the actual leaf area, and this increases the water volumne on the leaf area and so run off occurs.

Also Chemicals in general have gone up around 200-300 % over the past two years due to the high cost of production.
