C'day there AVB,
And many thanks for replying to my post.
I can only assume that you are talking about USA Roundup labels containers in your post.
I'll try to explain, the basic meaning of my post,
1. Using the rates I provided, will have a detrimental effect an most grasses that have a fibrous root system. These include Poa annua, Lollium perenne, Sporabilis africanus, Digitari didactyla, Elusine indica, to name a few.
2. The same rates will also have an effect on most flatweeds, such as Hypochaeris radicata, Trifolium repens, Cyperus rotundus, although several sprays will be reqiured for this one,
Soliva sessilis, Plantago lanceolata, Daucus carota, Taraxacum, Oxalis corniculata and many more.
If you are talking about the instructions for 1 acre applications, I refer you to the statement I made regarding some N.S.W. Golf Course Surerintendents, that have used this half-rate method on their Couch Grass fairways [or the U.S.A term for that is I believe Bermuda Grass], in which the correct amount of water and Roundup were added to the spray tank, after the spray nozzles output were calculated and pre-set to ensure the unit and speed of travel, as such, were set to deliver exactly that was required to do the job.
Having said that, my post was aimed for folks who have a backyard & front Common Couch lawn, who just want to get rid of any weed infestation they might have, using any container they can connect their hose to, using the guide in my post to work out their rate. Note: There are not many of us who have one acre properties in the urban regions of Sydney, although I could be wrong about that...
