Roundup Weed Killer

[johnbarry]

I sprayed roundup weed killer in the sun and was thinking was it too warm (28°C)

Here’s what it says on Rounup website.

Choose a calm, dry day to apply your Roundup when the temperature is between 12°C and 25°C.

Don’t apply when it’s windy

Drift may damage plants that you don’t want to kill

Don’t apply when it’s raining.

If it should rain within 6 hours of application repeat treatment may be necessary

Don’t apply in very cold conditions
Don’t apply in very hot conditions

Was 28°C a very hot condition, will it dry up too quick? or was it an ideal time.

I guess I will find out the results in a few days, however I am thinking it now.

Cheers

I did it last night, well evening as the dogs were not boarding with us last night. The weeds I hit do not look well today so hopefully it will work for you. It is now down to 20 degrees, so a good time to hit the little green nasty things.

Cheers Richard

I did them earlier, not near them now. I hope it works (at 28°) if not I will have to pick a cooler time next time.

28° is going by the therm in the car it could of been cooler, I never had a sweat.

Just treat the nasty stuff as a bio-hazard when you use it. The jury is still out on the safety of the  Roundup mix – just remember that Monsanto (the manufacturer) does not exactly have a water-white reputation for the environmental impact of its products:

Thanks Ed

This is the first time I have used Roundup and I think it will be the last, especially what’s said on your link.

I normally use  Resolva Weedkiller.

Also the roundup came out like blobs of foam not a fine spray.

As I said the jury is still out. I have still not found the end of the California trial, but imo the evidence presented so far gives cause for concern. Certainly not stuff for regular home use, and one worries at statements that say the EU will withdraw its permission to use.

The EU voted in 2017 to limit glyphosate’s license renewal for a period of only five years, and many European countries have announced plans to end its use within three years. “Countries like France and Italy and Austria are saying … ‘we’re not waiting three to five years, we’re moving as soon as there is a viable alternative,’”

Of course for Monsanto there are even bigger issues apart from potential court suites. If glyphosphate is found to be carcinogenic then it also threatens much of the Monsanto GMO seed business. (Plants are engineered to be glyphosphate resistant to enable liberal weed spraying to be conducted)

btw I’m glad to hear you were not sweating as the temperature limit is probably set to minimise roundup spray getting into your skin.

Ammonium Sulpahamate was for years a great weed killer until the EU, or rather I understand the Irish contingent wanted some extra tests that were expensive and not supported by other members. It can still be used as a composting accelerator but not as a herbicide/weedkiller on open ground. It has a interesting property of breaking down over a bit of time, 3 ~6 months to provide a nitrogen based fertiliser making it  great for the clearance of land that will be used for cultivation and so it is still widely used – but only outside of the EU. Sodium chlorate is another good weed killer though that can have other uses which are not so well appreciated by most people. Its persistence is far greater than the sulphamate so it is not so well suited to land for cultivation and it may leach into ground water where it will be stable and poisonous for some considerable time. Neither is currently licensed for use within the EU, though all weed killers beat the heck out of hand work when your hands are fairly crap.

Resolva contains di-ammonium glyphosate along with other packaging components to achieve its active status. So both Roundup and Resolva are essentially similar apart from detals of their formulations and neither appear to be very long lasting.

I hold no truck for either Monsanto or Merck so I am not aiming to support any such enterprise. All such products can have undesirable effects if misused, e.g by using them as drinks or hand lotions or breathing in fumes etc.

Sadly such uses have been tried either accidentally or by intent.

I see any product designed to kill something, it will be dangerous in other ways too (side effects). As science marches on, we find this side effects out, and keep restricting the market, untill in the end, (in this case) we will end up with poorer and poorer weed killers, that are more friendly overall.

I bet in the 60s, weed killer was some  tremendous stuff that worked 100% of the time. But would probably kill you if you got a lung full too.

We bought a new property 12 months ago, the garage was preserved inside with creosote. That nasty smell, was the smell of summer for me, every year me and my mum would do the front and back fences. Now we have to use the crappy water based stuff what fades and washes off, and need a many coats. At least it doesn’t smell of creosote. I never said I liked it, just it reminded me of youth.

I never did look up why it was banned. I bet that killed weeds.

Sodium chlorate brings back happy memories from my first job after Uni and the days of post-grad training. Some 22-25 years old friends of mine all shared a big house. Like most young males they had zero interest in gardening, and the resultant was a garden that resembled a jungle and brought down the ire of their neighbours and landlord. Something had to be down and sodium chlorate weedkiller was both cheap and plentiful, so they sprayed it very liberally all over the garden. Instant death resulted to the jungle and the garden soon became a brown wasteland tinged with white crystal specs during that long hot summer.

Unfortunately one night one of the young men threw his lit cigarette end into the garden. Very shortly afterwards what could best be described as a unconfined explosion occurred. By all reports there was a huge flash and whoosh — all the dead vegetation turned to ash along with most of the garden fencing. Cue for more irate neighbours!

The rest of us young grads did a ROFL , when this tale was recounted in the local pub. The consensus was that trainee salesmen with Arts degrees were unsafe to let loose in public.

Cheers, very interesting

I never knew there was so much info on weed killer’s bad bits, no wonder the weeds don’t like it.

Maybe go back to killing the weeds with a shovel (or Hoe), chop chop, slice slice.

John – that process does wonders for the visible bit above ground, but the advantage of the above mentioned weedkillers is that they also kill off the roots below ground as well.

[The Duke]

We use either resolva or roundal on the front garden once a year (needs doing) as it’s block paved and a bitch to do by hand and lengthy.

Takes ten mins to cover the lot. Then about 3 to 5 days later, a quick going over with a stiff yard brush un seats all the dead weeds.

[johnbarry]

Thanks JayCee

Not to forget, it’s harder and takes longer than weed killer.

oopppsss as Duke say’s

Cheers
John
