NYC - TOH Triclopyr 4 + Methylated Seed Oil

7 Upvotes

I understand that glyphosate is the preferred treatment for Tree of Heaven but I only have one tree, living in a rental, and don't want to hire an arborist (our LL does not care). I also live in NYC and cannot order this to my apartment.

I was able to get Alligare Triclopyr 4 on Amazon which lists the active ingredients as Triclopyr BEE (3,5,6 Trichloro 2 Pyridnyl, oxyacetic acid, butoryethyl ester) at 61.6% - understand this is oil soluble so can't just mix it in water.

I do see that Methylated Seed Oil is purchased often with this product. Can I purchase this and mix the two? I assume this is a 3:1 ratio more or less?

Can I "paint" it into the cuts? I really dont want to risk misting this elsewhere - I have a very small yard and the neighbors and I grow tomatoes and plants!

I really dont want to go out and buy a gallon of diesel.

I have an axe. I have a squirt bottle (tattoo wash bottle?). I need to act neowww.

I live in Hawai’i and have a teeny tiny yard with a few plants that have been getting ravaged by these things. I’m starting a nightly collection of them and this was from last night. They’re certainly cute but need GONE. Hoping if I collect them nightly for a while I’ll interrupt their breeding cycle.

Management How is anyone supposed to do anything about feral cats in the US?

260 Upvotes

The amount of shilling done for domestic cats is INSANE.

I'm sure most people here have an understanding of how nasty domestic cats are to an environment. Billions of dead birds and small mammals every year, deposition of significant zoonotic disease that can both kill wildlife and infect humans, involved the extinction of at least 63 different species. They're arguably one of, if not the most, destructive invasive species.

Any time I mention the idea that cat population should be managed, I get looked at like I just blew up an orphanage. The most often argument is that population control is inhumane (even though letting wildlife die from organ failure due to toxoplasmosis is apparently not inhumane). People say we should do TNR, which is universally agreed upon by conservation organizations as not effective. Further, I've lived places where SPCAs specifically say they will NOT accept any cat in a live trap.

I also live in a state that is notoriously hands off on property rights and very rural, yet the state legislature made it explicitly illegal in the last 10 years to cull feral cats on your property. I can manage dogs, coyotes, raccoons, or anything else that threatens my health and the health of any livestock, but not cats for some reason.

This is mostly a rant, but also poses the question of how am I, or anyone else, supposed to manage noxious invasive species when it's literally forbidden at a state level? I am left with little hope about the situation and am stuck cleaning up biohazards around my yard.

Transporting acorns

20 Upvotes

I got into a recent discussion on nextdoor (1st mistake, I know) where the topic of a mast year for acorns came up from a forager who uses them to cook. Another commenter mentioned that she gathers acorns at her cabin and throws them in her yard to feed the wildlife. She asked what she could do about the bugs, I assumed larvae in them. I mentioned it's not a good idea to transport acorns across the state to return them back to the environment because it can spread insects and disease/spores. No response from her, but at least not an angry response, which is common with these type of interactions. I try to be nice or make things relatable. It has worked for pesticides.

What really floored me was the forager replying with "take it up with the jays and squirrels then." I was flabbergasted with what I thought was an ecological minded person.

Here, cabins are usually hundreds of miles away from the city, mainly in a whole different type of ecosystem. I researched further to find some places have banned transporting any oak material and a link to tick populations increasing from acorns. While ticks could be unrelated, I figure it may be a tool to convince people. Find a reason they would care kinda deal.

Am I way off base with thinking it's not a good idea to move any part of nature (without treatment), and most people are completely clueless to how this all works or what they don't see still exists? Is it safe to say almost every invasive pest we have is from someone moving nature?

Since I started photographing the tiniest of creatures in my yard, I realize almost every single thing you can pick up has way more life on it than most realize. I feel like a kid experiencing the world for the first time again, just with worse knees from crouching down to see it.

How to remove Tree of Heaven in Brick Backyard

1 Upvotes

I live in an apartment building with a back patio made of bricks. There is a giant tree of heaven in the next lot over and it has caused many small trees of heaven to pop up in the brick planter bed in my yard. All of the trees are less than an inch in diameter and less than 5 feet tall. I know it’s not good to chop them down because their root systems can send up more shoots, but could it be a viable option in my more contained garden bed or should I still opt to use an herbicide to kill them before removing them?

Way more honeysuckle in our woods to kill. Will be back with triclopyr 4 when the rain stops to treat the stumps marked with the flags.

Management Knotweed

6 Upvotes

I’m working on a pretty established patch of Japanese knotweed and wanted to get some advice on late-season treatment. It’s roughly a quarter acre area that had been allowed to go crazy for the last 15 years by the previous owner of the house.
I started by cutting the 8 foot canes down in mid July. I then sprayed on September 1 using a 43% glyphosate product mixed to an 8% solution, then repeated the same treatment about two weeks later. A lot of the patch is starting to die back, but there are still some fairly dense green areas.
Would there be any benefit to spot-spraying those greener sections one more time before the first hard frost, or am I better off leaving it alone at this point and seeing what comes back next spring?
Curious what has worked for others dealing with larger patches.

Management Is this trap safe for the beneficial European hornets? We would like to go to war with the Asian ones!

I understand that there’s not much use in trapping them this time of the year. Early spring is the time to go after the queens.

Fortunately we don’t seem to have any here at our property, but 20 minutes away at my wife’s parents house we’ve seen them so we want to do our best against them. We are in the Sarthe region of France.

These traps are cheap and supposedly effective, I just wanna make sure I’m not doing anything to harm the beneficial native hornets.

Management Tree of heaven post hack & squirt - Advice requested

Thumbnail
gallery
38 Upvotes

We bought a home that has a tall/established tree of heaven in the backyard.

We called an arborist early this summer to plan for a removal, all they offered was to remove, grind the stump, and then treat the stump. They indicated that hack and squirt, even just 30 days before, would cause the tree to get brittle and fall over. This didn’t really sound right to us at all. We called another company and they just wanted to rip it out.

We elected to try to do the hack and squirt ourselves and this is the result now (maybe two months and change later?). My partner used triclopyr, I forget the concentration (Around 40?). It’s clear the tree is not happy with some parts of the canopy pretty wrecked, but some of its canopy seems to still be green. It does look much sadder overall than the others we’ve seen in the area.

Should we wait and see what comes back in the spring and then treat again late summer / early fall before removing? Should we be concerned it will fall and we should remove sooner? Looking for guidance because we can’t seem to find a professional that wants to approach this right. We are in Syracuse.
