Ether Jones Round-up is deactivated in the soil almost immediately whe
it does an ion-exchange with clay particles. It also decomposes in the soil. It doesn't decompose in the bottle or sprayer.
A follow-up question if I may. Does it matter what kind of water you use to mix with the Round-Up? I use well water. My well has som iron as well as other minerals I suppose. Do these impurities tend to deactivate the Round-Up?
The reason I ask is, everybody I talk to seems to have better luc with Round-Up than I do. They say the weeds are dead in a week. When I use it, it takes up to three weeks to see any difference at all; and sometimes I have to re-apply.
I'm not skimping on the mixture. I even tried tripling the amount.
I'm using it on weeds in my gravel driveway and between patio bricks. Also on my trail in the woods to clear underground on and around the trail.
A farmer friend even gave me a gallon of the commercial-grade stuff he uses, and it didn't work any better.
I suppose the next step would be to try mixing with distilled water. Haven't had the time to mess with that yet.
the kind of water that u use doesnt really make much of a difference w have rust in our water here on the farm and my hubby uses it for tan mixing of roundup. i think the thing thats most important is to mak sure that u get a good even coverage on the weeds that u want to ge rid of. some weeds do need an extra application of roundup especially if the have some herbicide tolerance or if u are trying to clear a reall weedy area. roundup is a contact herbicide which means that it kills off whateve it hits, it is also non systemic which means that it does not stay i the soil but breaks down quickly as has been mentioned ;). hope thi helps u some. cyaaaa sockiescat
