Title: Weed killers, really confused!!
Post by: Growing4twins on May 27, 2010, 13:10:02
Hi all!!

I have a big patch on my site that is just full of weeds, so i want to kill them b4 i dig.  However im getting really confused on which weedkiller to buy as they all seem 2 say "For use on areas not intended to bear vegetation". 

I recently brought some Resolva weedkiller total clear, but have held off using it due to the warning.  Is there any1 out there who could tell me if this product is ok 2 use?  If not could you recomend  a product which is.

Its really not easy to read the back of packets in B&Q when u have 3 yr old twins running around!

Thx!!

If you wnat to kill every plant in an area you want something that has glyphosphate in it (the resolva might...) This will take about a week to start working, leave it to work and after a couple of weeks everything will be dead, you can dig it over and plant straight away.
Don't spray / water the weedkiller if there is a draft, its very effective. Use on a warm day when the plant wil adsorb it through the leave and carry it down to the roots. Don't use if rain is forcast for the enxt 24 hrs.
Use the recommended amounts and give it time to work properly, don't start digging over until everything is completely dead, some persistent weeds may need a second dose.
Others wil recommedn the use of a spade first and digging them out by hand. Each to their own.

Personally I would dig out & compost the weeds, why waste money on weedkiller when you can use those weeds to improve your soil.
The people that choose to use weedkiller tend to go for glyphosate based products such as roundup, Resolva is a blend of glyphosate & diquat the time before replanting should be on the label if not then query it with the manufacturers. There is also an organic weedkiller available to buy online if you prefer something less controversial than glyphosate http://mistral.ie/details.php?code=R5002 (http://mistral.ie/details.php?code=R5002).

you could try white vinegar mixed with a squirt of washing up liquid for an organic alternative.  :)

Would that kill the roots? or just the top foliage ???

I think its pointless using weed killers at this time of the year as you are only going to knock back what you can see and not what has started to grow and it will. There is also a chance that some may be carried on the wind to your veg, tomatoes etc.
Get stuck in with a garden fork and get the roots out, its not the easiest option but its the best.

Last year I cleared an area on my allotment with glycophosphate.   I burnt the dead foliage.   This was in March.  Then after 6 weeks my neighbour rotavated it for me.  Planted potatoes.   Good crop.   Nobody has died.

Hi all weed killers,

Weedall is the very best to use as you can plant the same day, it is rather expensive but well worth it. I have a pressure sprayer, (about 15 pounds) It is one of the most useful tools I possess and I have no qualms about using it. It takes about five days to kill the weeds but it does no harm to the soil or the beneficial insects. The best way to use it is in the evening with a glass of wine in one hand and the spray in the other, heaven. Almost as good as going out with your tub of salt with the intent of killing the slugs and snails.

Regards to you all Queenbee

I made a non lethal slug launcher. You picked the slug up, dropped it down a clear plastic tube, pulled the trigger and a blast of compressed air blows the slug 100 yards to eat someone elses cabbage...............

There is no such product as weedall approved for use do you mean weedol? if so then which type there are 11 variations & all work differently according to what the active ingredient is.

Weedol 2 & Weedol Gun! which are based on Diquat.
Weedol Gun Max, Weedol Max, Weedol Ultra-Fast & Weedol Ultra-Fast RTU which are based on Pelargonic acid.
Weedol Tough which is based on triclopyr
Weedol Rootkill Plus & Weedol Gun! Rootkill Plus which are based on glyphosate and pyraflufen-ethyl.
Weedol Lawn Weedkiller & Weedol Lawn Weedkiller Ready to Use which are based on clopyralid, fluroxypyr and MCPA.

Spraying weedkiller whilst drinking anything let alone alcohol is never recommended. Getting weedkiller in your drink is not going to do you any good & not paying attention to what you are doing often results in the spray drifting to other areas affecting your own or your neighbours crops.

Hi all,  :)

I`ve used lots of glysophate, I finally realised its a waste of time and money.
Now I`m fastidious about weeding digging and hoeing. You won`t find a weed over half inch tall on my big plot and I`m getting there on my number one plot which I neglected because the blue tits were in residence. My pumpkin plot is thick with weeds, thats where I last used lots of glysophate, next week I`ll dig them all out before tilling.

This raises another point.

Vinegar based killer - £3.50/l.
Distilled white vinegar "v strong" - £1.50/l

How strong is 'v. strong'? Is not commercial stuff - as in killers - VERY much stronger than shop bought?
Title: Re: Weed killers, really confused!!
Post by: Baccy Man on May 28, 2010, 09:48:43
Horticultural vinegar (organic weedkiller) typically 20% acidity.
Distilled white vinegar typically 5% acidity.

Bear in mind that vinegar is non-selective & non-systemic it will kill any vegetation you spray with it, it may weaken but will not normally kill the roots.
If used excessively it will temporarily alter the ph of the soil although the effects on ph are short term & localised to wherever you sprayed it.

I dealt with bindweed using roundup it was very effective before planting raspberries.  Having been organic for 25 years it was against my principles but I knew that it would be pointless planting them otherwise since it would be impossible to dig out.  I do not see the point of poisoning anything else sincemost other things can be removed or just constantly hoed.

I just wished I had poisoned it the first time it arrived.

Not pointless but not effective on such a wide range of weeds. Mixing 5% with a natural soap product would help it adhere better improving performance.

So are we saying that vinegar and detergent is effective as a weedkiller.  Is it any use between raspberries does it effect the woody parts. 
Title: Re: Weed killers, really confused!!
Post by: Baccy Man on May 28, 2010, 10:42:52
Soap not detergent, soap is a natural product detergent is petroleum based.
Yes it should work between raspberries, no it shouldn't affect woody growth but avoid getting it on raspberry leaves.

Interesting article about Roundup. Does it not strike you as strange that Monsanto made Roundup and at the same time, genetically modified crops resistant to it? spot the error...

Weeding is as much a part of gardening as planting.  And i have bindweed and other rather obnoxious things. I just don't think that I really want to spray chemicals on the food I then feed to my kids, there's enough of that in everything already. Dig them out or cover them.
end of moan...

+If the weedkiller you bought says for non cropped land it will have content that is persistent in the soil so no good for growing things. Suggest you return it and ask for advice on a Glysophate based weedkiller. Roundup is the trade name Monsanto use for Glysophate. Nothing else will do the same job. Treat the weeds, after 7 days do whatever you want with them, pull em up, dig em in, then plant. Thats what the farmers do.

The over use of Glyphos is a travesty, much like the over use of antibiotics, Glyphos is one of the most effective and least harmful weed killers we have ever developed, if we must use weed killers then we should never use them willy nilly merely to save a little labour. Already resistance is building in the wild and so farmers are now turning to seriously nasty weed killers once again.

I don't know how anyone could take on even 1% of that information and still buy anything made by Monsanto, or feel they can trust any claim made by the chemical industry. Let alone feel safe enough to spray these products on their food crops while merrily sipping their glass of wine, like the spraying of the crops is part of their lifestyle choice. Crazy stuff.

...and if I come across as controversial I really just don't care, people need to wake up to this stuff.

On hte back of the packet it didnt say when to dig up the weeds, so i looked on westlands site & it said 7 days. if the farmers do the same then it cnt be wrong can it?? 

This is my 3rd year on my plot & it is the 1st time that i have thought about using weedkiller.  The part that im using it on is like a jungle, it has docs, brambles, nettles, long grass.  I just cnt get through it & keep an eye on the grusome twosome!!  Im really quite gutted that i have to do it this way.

Farming is broken, what farmers do they do to eek out a living and meet teh insane demands of tehir suppliers and customers. I would not use what farmers do as a model for good practice, because it isn't. Most farmers know what they do is wrong and many would do it differently if they felt they could.

I'd seriously have to think about why you are growing, if it is for the kids I presume it's because you want to produce healthier food for them, in which case following the methods of the commercial farmer is pointless, once you've paid for seeds and chemicals you are unlikely to save much money either and may as well just buy from the shops. How about covering some of the ground and working on it a bit at a time. Or maybe cover with cardboard and mulch heavily, growing in the mulch.

My old plot got weedkiller sprayed, not by me, but by a newbie who got her plot numbering wrong and sprayed my plot in error, the bit she sprayed was not more weed free than my other bit, it just grew a different set of weeds
Title: Re: Weed killers, really confused!!
Post by: Jeannine on May 30, 2010, 23:27:25
It might have already been said but consider this.. cover all the plot in black plastic, with the intention of leaving it there at least until next season, this will kill off a lot of the weeds without chemical help. You can plant through the plastic with many veggies while the plastic is doing it's thing. You may not get a wonderful harvest this year but in the long run you will have a better plot. Bear in mind that the farmers hardly ever have a weed, think about fields of crops, they all seem to be weed free, so spraying for them is not the same as starting with the jungle you seem to have.

I can sense your frustration and truly do feel for you but spraying is not as miraculous as it might seem, if it rains shortly after it probably won't work and the weeds do come back but if you could get your plot relatively weed free you would have a good start on next year. You could then roll back a few feet of plastic, dig that, dig out any leftover roots and move on. With a plot as weedy as yours it is like trying to turn the tide.

I totally agree you can't follow the farmers and I am in no way putting them down, they have to do what they need to do but you have other choices.

Consider covering it,this time next year you may have a good plot. There are lots of folk  here who can help you regarding planting through plastic. Mant folks have had to do just that.

I try to stay non judgemental but have to honestly say I  no longer trust Mansanto.

Good luck

Post by: grawrc on May 31, 2010, 04:24:01
I agree with the previous two posters. Strim/cut it back then cover it with cardboard or black plastic. If you can't cut it back cover it anyway. A couple of months on the weeds will have died back. The longer you leave it the clearer the ground will be. Keep an eye on it though because some of the "fiercer" weeds will try to go through or under your covering so will need to be cut back/ dug out if and when they do.

You can, if you wish,  plant through whatever you put down, as Jeannine suggests.

I certainly wouldn't be happy using weedkillers near young children. Monsanto (Roundup) have lied about their products for years so why would you trust them now?
