Answer 1

You need to use, Diuron, its used to control a wide variety of annual and perennial broadleaf and grassy weeds, as well as mosses. It works by inhibiting photosynthesis and is taken up by mainly the roots. It can remain in the soil for up to a year depending on the soil type, fertility, and amount of organic matter present.
An other good killer to use is,Dichlobenil or carston G, it is used and effective against all types of weeds and is absorbed from the soil through the roots. Applied to the foliage it causes reduced cell growth in the growing tips and inhibition of germination of seeds. It dose not dissolve easily so is applied as granules. For non-selective weed control, apply in spring just before growth is due to start, treated areas should not be used for about 2 years. It can also be used in still water to kill aquatic weeds.

I suspect you are talking about a total weed killer (kills all vegetation) with a residual effect - stops re-growth up to 12 months.
Total weed killer works systemically through the soil to the roots where it stops re-growth (ground sterilant).
So you need to saturate the soil to be absorbed by the roots.
A product like BARREN contains bromacil (ground sterilant)
and also 24D (This will kill the weeds growing and must be sprayed on the weeds) (like roundup). Barren has a dual use.
The performance of a total weed killer like EPA registered BARREN depends on many factors like rain, soil, vegetation, and resistance to herbicide through use.
So testing a small amount first to see performance is prudent. Remember to read all label instructions before applying.

Most likely you have to wait till you see the "green of their eyes" before you shoot that stuff on. It kills the weed and its roots. So you have to let it die and lay there for a bit. If you go and cut off the tops before it works its way down the root system, you basically cut off the poison from going any farther.
Spraying the ground neutralizes the spray - wasting your money.

Answer 4

The only 12 month weed killer I have ever seen will kill the grass too. The killers for use on your lawn will definitely not last 12 months.

Round- UP...........Last for the entire summer I don't think any of it will last for 12 months....You definitely won't have to be weed wacking every other week (or week)
Even tall weeds and grass will die off.
If you spray right after the whacking it will keep that way..........
