Herbicide in Ontario

Hey everyone,

I've been doing alot of reading on here, and it seems like everyone uses herbicides to control weeds.

Unfortunately in Ontario, Canada they are banned. And although some still use it, I'm unsure if I should as I have a dog, so do the neighbors and I live right near a lake.

What should I do? I have a lawn that is full of weeds, missing spots, and lumps everywhere. (Just bought the house).

Should I focus on overseeding, fertilizer and aeration?

Getting weeds under control should be your first step. Only you can decide what is worth doing with respect to banned herbicides, but these products are used in the US without issue.

For reference golf courses can use these products, just not the home owner. You can also get them if you have a farm or need to get rid of poison ivy. What does that tell you about how dangerous these things are.

I live in Ontario too and have ordered everything i ever wanted from seedworldusa.com never had any problem. Just had to pay the taxes at the border.
For safety of pets read the label. Its usually safe after it dries.
I literally made over a dozen orders and each was fine. One order of micro nutrients was leakimg and they sent me a new jug for no charge. I got midnight grass seed
, tenacity and my two favs T Zone...holy shit that stuff works and straight triclopyr.

Just try it..it os a god send for us canucks. Just shipping is a bit pricey

How would you do this without something to kill what is there?
It would be zero fun, but a sod cutter if he wants to do it environmentally. I'd rather use glyphosate, but it's an option

Glyphosate is still available. It's The bottles of round up behind lock and key at CT, HD, etc. If you're concerned about herbicides, imagine this, I've sprayed 14oz of total product and farmers will throw down hundreds of gallons on top of their vegetable crops. Home owners can't use it because it "might" get onto our foods but farmers can use it where it definitely gets on to your food.

When I spray, I'm careful and take all precautions but the liberal hypocrisy is ever present in my mind. They uglified our homes and continue to poison us.

Solarization with plastic is also an option. I'd argue that that much plastic is more environmentally damaging than glyphosate but it works.

Solarization typically takes 4-6 weeks at a minimum right? Or can it be sped up somehow?

Yeah. That's about the length. I assume most currently growing weeds will be killed quickly. Don't think you'll get up to temp to kill everything until 4-6 weeks. We're also on the cooling down side of the hottest time of the year so it might not be great for this year.

Would def use glyphosate if you can.
So you're saying wait 4-6 weeks before I use any herbicide?

That 4-6 weeks is how long it takes to kill via Solarization. That'll knock everything out but uses plastic to heat the soil up to high temps. Other herbicide options have a waiting time between when you apply the herbicide and when you can seed.

Glyphosate, you can apply to all of the weeds on the same day as seeding. That might be your best option as we're already getting into prime time for seeding. That 4-6 weeks puts you at/near the end of the seeding window.

Unfortunately you don't have 4-6 weeks to waste with solarization. We are currently in our window to seed in Ontario. Ideally you want to seed by end of month, latest. Here are the 2 options, the way I see it:

1. Buy Par 3 off eBay. Blanket spray as soon as you get it. You likely won't get 100% kill (usually takes 2 applications). You can seed 1-2 weeks later.

2. Nuke your entire lawn and seed right away (no need to wait 1-2 weeks like above). You will need glyphosate (RoundUp) to accomplish this.

Here are some factors to consider:

* Do you have your seed already?
* Do you have your irrigation dialed in? Are you able to keep the area moist throughout the day?
* Do you plan on doing any leveling?

Time is not on your side. If it were me and I was new to lawn care, I would go with option 1. Spend the next 2 months getting familiar with my lawn and best practices. Then I would re-assess my lawn next Spring and put a plan together for Late Summer (August) - whether that means feeding the lawn or doing a complete reno.

With regards to your original post about chemicals, many members have kids and pets. As long as you keep your dog off the lawn for a day, it will be fine to re-enter the lawn once your spray app is dry. With regards to living near a lake; unless you live on the lake itself, what is your concern? Only a heavy, heavy rainfall would cause significant runoff of a recently sprayed app. Just make sure you spray when the forecast is clear for a day or 2.

Hey thanks!!! I definitely need to do some leveling, as well as grind some stumps from some previous trees and thick weeds I had to remove. What do you suggest for this? What top soil mix? Etc

I'll try to order some par 3, and reseed like you mentioned, but not sure what to do with leveling the lawn.

Got the par 3. I need to cut my lawn, so I'm going to do it a few days before like it suggests. My question is, should I bag my clippings so that the spray doesn't get bkocked?

Thanks
I don't bag. I do wait like 2 days after mowing to spray so they grow a little. I spot spray with 3way and never broadcast spray, though.

What do you do? Selective spray? Is there a reason you prefer your method?
 
#22 ·
Spot spray apps are needed when you have just a few spots in your lawn with weeds. Blanket or broadcast apps are needed when your lawn is over run with weeds.

What you do with the clippings is irrelevant. This herbicide works on contact with the weed surface.

You will have to wait 1-2 weeks to seed, if that's what you plan on doing. It's getting very late to seed in ON.

Here's my experience with FeHEDTA herbicide, which you can get in Ontario. It definitely kills the leaves of creeping charlie, clover, dandelion, and oxalis. It will not kill the roots, so you need to apply it every couple of weeks until the plant is dead. It is expensive. I tried it because my wife is very fussy about chemicals and I wanted to avoid an argument, and it worked better than I expected.

Upside: You can seed pretty much as soon as it's dry, so if you're running out of time it will help you at least defoliate the weeds.

Here's the pics. Same spot one week apart:

I don't like spraying it more than I need to. I walk in straight lines on my lawn and spray as I see weeds. I have started using pre emergent (Prodiamine) and that I have to blanket spray obviously.
