Roundup: Should It Kill Poison Ivy?
It's been about five days since I first sprayed some poison ivy with
Roundup - with a touch up application yesterday. I'm not seeing any signs of distress in the stuff. OTOH, 3 days on crab grass and the stuff is clearly dead or on the way. Bottom Line: Should Roundup be effective against poison ivy? If so, what timeframe? -- Pete Cresswell |

Aren't there various varieties of "RoundUp" -- for different weeds? We don't have poison ivy, but we have poison sumac, and a weedkiller specifically labeled as being for poison ivy, oak, sumac, etc. (don't recall the brand or name) leaves our poison sumac looking very ill after only a couple of hours.

So, I can report regular Roundup doesn't work. I expect something Poison Ivy specific has a better chance. -- Dan Espen |

alt.home.repair: Bottom Line: Should Roundup be effective against poison ivy? I had rampant poison ivy in my yard when I bought the house. I physically pulled most of it out and treated the rest with a brush killer (it might have been a Roundup brand product.) I seem to recall trying regular Roundup but it wasn't very effective. The brush killer worked very quickly, like within a day. P.S. - I haven't seen any more poison ivy back there for many years. However, I saw a couple of sprigs poking up this summer. I killed them, but it reminds me that the stuff may never totally go away. |

Most retail versions of Roundup are too dilute to effectively control brushy and woody plants. You need a minimum 41% concentrate of Roundup to handle them, and that gets expensive. Another highly effective herbicide for woody plants including poison ivy is triclopyr. Read your labels and buy the strongest concentration you can find. |

Roundup: Should It Kill Poison Ivy?
I've been using regular Roundup on poison ivy for years. In my yard and surrounding area (I like to keep a buffer zone) it works fine.
I mix mine from an old bottle of concentrate that's been in the shed since I got the house. I don't make it super strong, just the normal mix. |

Since Pete is having a problem, I'd mix it at 4%+. If you read the directions, to kill tougher weeds, they call for higher concentrations, up to about 6% I think. If you're using the stuff, you can get the ~48% concentrate for about $65 for a 2.5 gallon jug. That's orders of magnitude better than buying it pre-mixed or even the concentrate at HD, etc. That's for the generic glyphosate with a sticking additive included. There are also brush killers that are more effective against that type of stuff too. |

There are also brush killers that are more effective against that type of stuff too. I have used regular Roundup and some generic roundup with an added chemical or two that work well. I think the wetting or sticking additive is important to the poison ivy. Without it the chemicals tend to run off the leaves. The chemicals are absorbed by the leaves mainly so spray them and not the ground around the plants. YOu need to look at the concentration on the jug. Many of them are made to be deluted and often the lesser concentrations will cost more to make a given ammount of than the higher concentrations. |
Roundup: Should It Kill Poison Ivy?
years ago i had a bad poision ivy problem, poision ivy killer just made it wilt for a few days, same with roundup, just wilted then it came back stronger than ever.
so at the suggestion of someonehere i mixed roundup 50 / 50withpoision ivy killer. i amost felt bad for the poision ivy, they just rolled up and died, i felt like a mass murderer... do note mixing breaks some federal law, but going to my doc for pision ivy is worse. the chemicals are absorbed thru the leafs. so dont trim or pull the plants just spray the leafs for max kill. and DONT BURN THE DEAD BRUSH! you can get poision ivy in your lungs.. |

Roundup alone is not terribly effective on poison ivy because of the oiliness of the leaves. You need a good surfactant mixed with the roundup. Some people use a bit of dish soap in the mix - some a few tablespoons of diesel fuel. I know the diesel fuel works. Generally knocks it back pretty good in about 3 or 4 days. |

Mix both to the highest concentration listed on the label. It still takes a week before the leaves start to curl and up to a month befor they go brown. The Enlist system mixes 2,4-D and glyphosate. That's for fields where weeds could be resistant to either because both had been used extensively. For poison ivy, I don't see the advantage of mixing. If after a week, I don't see results, I assume it didn't absorb enough. I spray again. That didn't seem to work with some Spectracide 2,4-D stuff I got for buckhorn plantain. Seeing no results after a week, I'd spray again. There seemed to be fewer after I sprayed, but I didn't know why I never saw any shriveling or dead plants. After a couple of years, I quit spraying and began cutting roots with a sort of forked bayonet. I had to bend over thousands of times, but it's fun when you get used to it, and it worked. I haven't seen poison ivy resist repeated spraying. |

I mix it, generic, at 2% to kill common broadleaf weeds.. If I have poison ivy, which is not frequently, I mix it 5%. And it has a surfactant. It works. But if you have a lot of it, then a brush killer product is more effective and surer. It's also temp dependent. When it's hot, Roundup works extremely well and fast. If it's 45f, not as effective and takes much longer. |

It may knock the leaves off but it will be back. You are far better off with a Triclopyr based product, preferably mixed with a "sticker". Diesel works great. You don't need a lot. A little spritz will kill weeds like PI dead. It is what we use on Brazilian peppers, air potato and Ear leaf Acacia. Diesel? Fuel? Yup. It was the original recommended surfactant for Garlon 4. This is not something you are squirting out of an airplane. You just need to get some leaves with a few drops each and the plant will go belly up in a week or two and never come back. I typically treat an acre and a half with a 16 oz Zep bottle and have plenty left. Good to know. I've been using industrial Roundup which works well but they always return awhile later. I end up just pulling the roots. I'll do the diesel this summer. Thanks |
