Kill English Ivy

[RalphVa]

Been too rainy without a couple days in between to try anything else yet. Still no apparent effect from when I sprayed the triclopr solution. Think I'll try mixing the vinegar with salt and dish soap first. Gotta get a couple days with sunshine. All of a sudden we got hit with 7 inches and now more forecast these next 3 days. Gotta wait a while.

I'm not a fan or 24,D. It is so easily volatilized. You could spray it and then kill something a mile or more away where it condenses. I'd only try it via painting on. Think excess can harm water life stuff if it gets onto the ground and runs off via some rain. I'd have to check this but think it's so.

triclopyr takes a few weeks to really see an effect. I use it on poison oak. I have tried the usual 1% solution for foliar application on ivy and did not have a lot of success. It knocked it back a little but that's all.

I use RoundUp on English Ivy and Poison Ivy with good results. Higher concentrations work faster but even a light application on a bright, dry day will kill it in s couple of weeks.

We have Yaupon here that is invasive and hard to kill. The recommended approach is spot spray with 20% Garlon & 80% Diesel applied as a basal spray in the spring when it's growing. May want to check with your county Ag agent to see what they have to recommend.

That Garlon + diesel works well on poison oak. It kills the plant dead. Foliar spray kills the leaves that get sprayed. If you miss some the plant won't die and will come back. The difficult parts are getting to the stem and finding a sprayer and nozzle that can stand up to diesel.

A couple things to keep in mind... You want to apply the herbicides when the plant is growing vigorously so it absorbs the chemical quickly. Hot and dry weather means poor results most of the time in my area because the plants are semi-dormant or resting. The other thing is to use a good surfactant especially on ivy that has waxy leaves. I've had good luck with both glyphosate and with generic crossbow (crossroads from RK), when surfactant is added to the mix.

X2..
Don't weed whack it before applying glyphosate, plants need to be vigorously growing and gly is absorbed through the leaves. Most formulations of Roundup or glyphosate come with added surfactant, adding any additional sticker adds nothing. Only something with a name like original formulation wouldn't have the added surfactant. And ivy is notoriously hard to kill, if it were me I'd go with a 3 or 4% solution. You won't need much, but that stuff can take up to 2 weeks to show results
Triclopyr isn't the right stuff for what you want to do, that's more for woody brush and trees. As always, read and follow label dirrections.

Deer were about to eat all of the ivy off the retaining wall where my brother lives. Now he has a small dachshund that goes near the wall fairly regularly and the ivy is growing back. He thinks they are cautious because of the dog's scent. The cats aren't even afraid of that little guy.
