Herbicide question.

Lawnmowing and lawncare is my specialist area so I may be a tad out of date with general horticultural knowledge especially herbicides. That said I'm confused.

We are ocassionally asked to apply weedkiller to paths, patios, driveways etc and with the demise of sodium chlorate have sort alternative treatments. I recently purchased a container of Deadfast weedkiller which was specifically advertised and labelled  as "for paths, drives and wasteland."  Upon reading the instructions this product is simply a spray on systemic contact weedkiller and not a residual herbicide that would both kill existing weeds and prevent further growth over a period of months. I therefore cannot see how Deadfast can be promoted as specifically for hardstanding areas.

I would be interested in members comments and advice on what residual herbicides they use on driveways etc.

The residual that I know and use, Pistol, is not to be used on non-permeable surfaces for environmental reasons I guess. It is used on shrub beds, mowing lines and, mulched areas, chipped drives etc.

Roy, if you are not qualified or insured to apply pesticides comemrcially, I strongly suggest you sub-contract it out to someone who is.

 

The product you mentioned contains Sodium Chlorate and was not licensed (?) to be applied comemrecially, only privately I believe. My view is that anyone still using Sodium Chlorate needs to SERIOUSLY reconsider. Commercially it been banned for years (over 2 years ago). For private use it has been banned as well. I would NEVER use Sodium Chlorate ANYWHERE now. Its a totally toxic product. See: http://www.pesticides.gov.uk/prc_home.asp?id=2623&link=%2Fuploa...

 

If licensed, look at Pistol or ProShield (~£120 / 5L). Neither can be used on hard surfaces.

The operator is licensed and Deadfast no longer contains sodium chlorate.

The pesticide agency website shows what's being removed and when. Sodium Chlorate has been recommended not to be used commercially for along long time, although available thru garden centres for private use right up until it was banned.

 

What's its active ingredient now then  - I understood it was Sodium Chlorate when it was removed from sale and the product was never replaced ?

 

Pistol : http://www.pitchcare.com/shop/professional-total-weed-killers/pisto...

Pro Shield : http://www.ld-uk.com/product_info.php?cPath=31_36&products_id=3555

 

We use Pro Shield for "on label" use only

 

The problem is with the ingredient used to provide residual effect and how it needs soil to lock into. If applied to handstanding, it can get washed off into the waterways. I believe most people use Glyphoshate products for handstanding (but therefore no residual effect)....

Thats a new one on me.

 

During our training we were told of the importance of choosing the correct type of herbicide whether for horticulture use or industrial use for example, but we didnt touch on the subject of not being able to use a 'garden' weedkiller commercially.

 

I cant find a pdf of the label of this particular herbicide, but im in B&Q this week and plan to investigate.

Commercially, ie for financial gain. In someones garden.

 

The paths patios and driveways mentioned at the head of this topic are i suspect falling into your 'home and garden' catergory (if for personal use at home), though like i said this specific term wasnt mentioned when i did mine, maybe as it doesnt fall into the catergories that attract certification requirements according to that page. 

 

Are you stating that it is illegal to use an amature product such as this professionally (my original question) ?  something i hadnt experienced.

Unless they changed it since my training (and I'll check with one of my guys) it comes under the the Definitions of 'Field of Use' on the Statuatory Label.

 

Classifications below. Use outside of the product's approval designated "field of use" is technically illegal. They should have covered this in training....

 

So a product designated "Home or Garden" is not approved for use in amenity horticulture UNLESS there is a MAFF Off-label approval code.

 

The moment you use any product commercially (ie for financial gain) you need to be careful in this area and pay attention to the labels.
