A plant may be doomed before it dries up. My experience has been that if glyphosate is on the weed for two hours in warm sunny weather, you've killed it. Then it's only a matter of time before it starts to show the obvious signs of yellowing that shows you it's really dead. But in reality, it's been dead for a long time before that. Thanks for posting the video.

[@newcoyote]

I have used glyphosate for years and have a pretty large sample set. The most significant factor in the efficacy I have found is temperature. This is irrespective of the plant's stage in growth. Hot dry weather is far faster than cooler damp weather. This is consistent with most plants I have applied it to. There are of course other variables and this is just my anecdotes from observation.

[@newcoyote]

@Bruce strkland there is a product called Weathermax (the Brand name from Roundup that only needs 30 minutes prior to rain.

[@1860wright]

What ratio do you use

[@newcoyote]

@@1860wright 250-300ml in an 18 litre sprayer.

[@milesaway3699]

I use Spectracide. Visible results the next day. Somewhat satisfying.

[@heiditaylor6206]

I so understand the satisfying part. I walk out there in the morning and hope I see them dying. Makes me happy when I do!

[@stephensmith9334]

needs to be in the 60s n dry for best results n add dish washing soap or crop oil to make it stick to plants better

[@TheHulkNorris]

I watch this video now, 4 years after publishing. How does it look now? Please update!

[@rizzotto139]

Thanks just SICK!!!! 😂😂😂😂😂🤣🤣🤣🤣🤣🤣🤣😂😂

[@Shaun137]

I'm watching it 8 years later, maybe a whole load more grew lol.

[@oscarbear1043]

Some weeds are hard to kill with glyphosate due to underground tubers or large tap roots which regenerate. In winter glyphosate can take 3 weeks to work. Remember always wear PPE even with glyphosate. They may say it’s safe but thats if used as directed only. Do not spray under sub-optimal conditions as this encourages resistance, which is becoming a problem in some crops. Just think what is occurring with antibiotics due to irresponsible use.

[@lawncarelife]

Thanks for the feedback

[@CarlsVlogs]

Hello from Uk ye i sprayed the weed killer on our weeds and its a very slow process. Thanks for showing.

[@lawncarelife]

+prospect4186 glad to hear from someone in the UK. I wonder if what you sprayed contained glyphosate

[@CarlsVlogs]

Im not sure i only go buy recommendations from the staff in the shop.

[@logangomez4475]

Monsanto?

[@MrTonyharrell]

Good topic/video. I sprayed a fenceline and came back two weeks later and the fenceline was brown but it looked like someone had mowed with a 21 mower along the fence. Like it stunted the growth.Seeing that, I purposely mixed at 25 percent of recommended strength for fencelines, worked great and the fenceline looked really good. You can also overspray glyphosate over green woody ground cover if you get weeds popping up in them.

[@lawncarelife]

+Tony Harrell thanks for the info.

[@Mizanur28]

No ants were harmed in the production of this video.

[@MrGrzegorz22crewe]

😂😂😂

[@iamswoll]

There is a global shortage of glyphosate so the price of these chemicals have went up 200%. if you can even find it. I was glad I was able to find some, I cant find the Ranger Pro anywhere. Crossbow which has 24d in it is good to kill small trees and vines like blackberries. You should use some of that crossbow, that is good stuff.

[@timberslasher4899]

Pure glyphosate sprays are slower but just as good. Takes about a week at 2 ounce per gallon and wipes out everything. Compare And Save Brand is the best deal. Enough concentrate to make 200 gallons is 80 bucks on Amazon. It takes a good week, but it dont discriminate.

[@drummin2dabeat]

RoundUp is NOT [ just ] Glyphosate. What RoundUp has done, is figured out the secret formula to ensuring that impatient (and, frankly, ignorant) consumers don't grumble and become dissatisfied with the product, returning it to stores - while at the same time, allowing the active ingredient (Glyphosate) to be able to travel down into the root stem and systemically kill the plant. It is a delicate balance - because if you kill the leaves too fast with an acid (like Vinegar), then there is no time for the chemical to travel down to the root stem and the weed bounces back because it was not killed systemically at the root. To the contrary, If you use PURE Glyphosate (with no acid additives), then the chemical coats the leaves and has all the time in the world to get absorbed in and make its way to the root stem and do its job (more effective kill but works slower).

[@bobomonkey702]

Thanks finally someone who knows his stuff and explained it right.

[@Strongman0307]

Ive never had a successful application of roundup actually work long term

[@dagrote1]

You might have killed that plant, but other seeds in the ground around it germinated after your application. Glyphosate kills only living plants that are actively taking up nutrients.

[@jr42a1]

Heres the deal... First you need a still hot /warm day with no rain forecasted a few days in the near future OR WIND the day you spray. Take a 25 gallon spray tank on a 3 or 4 wheeler and add 1 gallon of crossroad (farm and home substitute),1 gallon of Pramitol,1 gallon of bean oil/paraffin oil (to make sure mixture sticks), and 1 gallon of intimidator (farm and home substitute).Keep the mixture mixed/agitated at all times while spraying.SPRAY AS LOW AS YOU CAN !! Youll never see vegetation again for 2 months maybe more. Results start appearing in hours not days. Just be careful and mindful cause its a hot mix with wax/oil to keep it sticking.. It will knock down 10' brush no problem and also any ground weeds/grasses.

[@Chris-zu4es]

today roundup has no glyphosate is it as good as before?

[@Dabayare]

Mine never does anything first time.

[@datboymike806bme]

Mix stronger

[@GettingtheTruthOut]

I use 50.2% glyphosate. Having a surfactant also makes a difference. People need to understand that glyphosate works by breaking down the amino acids in the plants. These are essential acid proteins that when treated, kills down to the root of the plant. It takes a few days to see the effect. But, buy the good stuff, not what they sell at Home Depot or Lowes if you have brush you're trying to kill. For woody plants, use Garlon IV Ultra, hell, Garlon IV is what can be used to kill trees too if you like. Drill a hole in a tree, inject Garlon IV and it will be completely dead in 3 months, any tree, any size.

[@Puppyjans]

i use 80% im sure that stuff would burn god

[@WXUZT]

Glyphosate inhibits shikimik Acid pathway and not Amino Acid synthesis.

[@h.i.m.dishonmaurice2599]

Jason, cool video as usual. However, did you mention the ratio that YOU mixed it at this time? If you did I missed it. Thank you.

[@lawncarelife]

+Dishon Maurice I tried the test out before mixed at 2 ounces per gallon and the weed died but it took a while. This time I used closer to 5 ounces per gallon

[@h.i.m.dishonmaurice2599]

Thank you Jason

[@shinymensdressshoes]

How well does it work on dandelions? Also, do you have to soak it so much?

[@AmitSharma-re4xu]

It works, Yes soak the leaves and twigs.

[@GMPLDR]

Hot long willnit take for another unwanted weed/bush to grow back in the area after?

[@fpdima]

Once the weed is dead do you pull it from the ground or leave the dead body to rot???

[@cgasucks]

Let it rot...

[@Muppet92954]

I feel like no one talks about that part of what to do after things are sprayed and dead, which seems like important info to kno 🤔. Thanks for asking and thanks for an answer.

[@chimkinnugget5221]

@@Muppet92954 I feel like u have to eventually pull it out if it’s grown into a bush along with other weeds, I doubt u would want dried up dead plants on your walk way or wherever after u sprayed them

[@bhaumehere2336]

Round up can kill sericulture tree which is age 10 month. Please reply

great video..but can u tell me..i have a 500 ml spray bottle..how much glyphosate mix in 500 ml water?

[@AndrewBartram]

sunil kumaar sharma 2.5ml to 5ml for most applications

[@silentkiller083]

I use 20 ml

[@iamswoll]

Does the cheaper brands not work as good?

[@lawncarelife]

+Daniel Martin as long as the active ingredient is the same, the results should be similar

[@jimjimerson6865]

Yes, cheaper brands of bleach have a similar effect when you drink them. Dimwit.

[@FeelFree3]

What is the concentration of your Glyphosate after you mix it with water?

[@adventureguy4119]

3 tbs per gallon.

[@DelsLawnCare]

Great info.

[@lawncarelife]

+Dels Lawn Care thanks

[@gulsadiq2876]

can this be used for Japanese knotweed if yes how to mix it?

[@rodneyburke2202]

Glyphosate can basically kill any plant even a tree if u used enough

[@pesonacinta503]

It's safe to use glyphosate or paraquat instead???

[@ShermanT.Potter]

If you're asking the question, DO NOT use paraquat! Wicked stuff.

[@adventureguy4119]

I wasted so much money on round up

[@coollasice4175]

Yo! What kind of weed was this???

[@deborahhyde]

you make annoying sounds after you talk.

[@lawncarelife]

If I spent five minutes with you, do you think I could find something to criticize you about? Would you appreciate it if I said it out loud to your face or is there times when it's better to keep it to yourself?
