NanLaew Posted November 23, 2015 Share Posted November 23, 2015 I need some for selective zapping of the tough little weeds that keep popping up around the cracks where the cement from the driveway meets the street at the front gate. Any clues? Not seen in the usual places with small garden sections such as Homeworks, Homepro, etc.. Link to comment Share on other sites More sharing options...
NeverSure Posted November 23, 2015 Share Posted November 23, 2015 I'm not sure what you want. With herbicides the term "selective" means it kills just one type of plant. Weedmaster is selective in that it kills broadleaf plants but doesn't hurt grass, for instance. A non-selective herbicide like Roundup kills most plants it come into contact with. The patent on Roundup has long since expired and there are generics that are much cheaper but contain the same chemicals. Roundup is typically 41% Glyphosate, and I buy a generic called Eraser that is also 41% Glyphosate. It works the same. I put 3 US ounces in 1 US gallon with the 41%. That's 3 parts product and 128 parts water if you want to do the math, especially if you find something other than 41%. Cheers. Link to comment Share on other sites More sharing options...

NanLaew Posted November 24, 2015 Author Share Posted November 24, 2015 My mate recommended a local product and I bought some yesterday. Once I try it out, I will post a picture here so that others can find it. Link to comment Share on other sites More sharing options...

It is 2 to 4 dl to a 10 gallon tank, 20 to 40 ml to the litre. The name glyphosate is written in English on the product, usually to be found on the bottom shelf so that thirsty kids can have a swig.

xylophone Posted November 24, 2015 Share Posted November 24, 2015 How much is the cheapest to kill any kind of green ? Thanks. Try Sodium Chlorate (but don't mix it with sugar!!) Kills anything green through leaf and root contact. Some trade names for products containing sodium chlorate include Atlacide, Defol, De-Fol-Ate, Drop-Leaf, Fall, Harvest-Aid, Kusatol, Leafex, and Tumbleaf.

LennyW Posted November 24, 2015 Share Posted November 24, 2015 This is what you are looking for, Thai Roundup, 48% Glyphosate, hence the big 48 in the corner, most of the mom n pop type hardware/garden centre type place have it, quite common.

lonewolf99 Posted November 25, 2015 Share Posted November 25, 2015 instead of pouring mad dangerous chemicals all over the shop...just pour boiling water with some salt directly onto the base of the plant/weed you want to kill. Standard electric kettle full dribbled onto the plant and its base. Link to comment Share on other sites More sharing options...

Nothing easier than dashing down to the bottom of your garden with a kettle of boiling water and treating a 20 square metres of weeds. Mad dangerous chemicals? Try cutting down on the use of petrol, that might be more significant. Link to comment Share on other sites More sharing options...
