Spraying weeds around stored equipment

I need some practical advice, not the kind you can find on the label. I have a gravelled area where I park my old implements, outside and exposed to the elements. This year I have grown a rather hardy group of weeds, under and around the old, discs, plows, rakes etc. The tractors and balers are in the barn.

Question: Can I spray roundup on these weeds (and naturally get some overspray on the equipment) without causing undue damage and corrosion? This is all old equipment, the paint is mostly gone and the value left with it.
 
You can get 24D that is supposed to be easier on equipment. I've purchased it by the gallon to use around the barnyard in my pull behind sprayer (not crop sprayer). It is milky white. I don't think it works as well.

They will all say they are non corrosive or safe, but there's a reason sprayers rust at the joints and pins freeze up. That stuff is hard on things. If it were me I would use something with more of a residual so you are constantly doing it. Roundup is contact only. Watch your runoff.
 
Edd,
No more damage than rain and dew normally cause, AFAIK. There shouldn't be anything particularly damaging about Roundup or other glyphosates.

If you are using a hand sprayer, mix 2 oz. of the 41% Roundup per gallon of water, and soak the weeds thoroughly.
Some of the tougher weeds don't seem to be effected with a weaker mix.

I should have mentioned that Roundup claims to be rain - safe after 2 hours, but I like to give it a little more time than that if possible before it gets rained on.
 
Got an area like that where I empty the sprayer about ever timer I have roundup left. Keeps the weed down and have not noticed any problems . There is also Primatol or something like that will kill the ground completely.
 

jm,
Are you just dumping the roundup on the ground?

It is supposed to kill through foliage contact only, rather than being a soil contact herbicide.

Pramitol is a good one if you can still get it. It kills the ground for several years so you don't have to spray again in a month like you do with glyphosate. Pramitol will leach out sideways some so be careful.
 
Davis SC,
The first good rain should pretty well rinse off whatever residue is left on the metals. I think most damage from spray solutions is due to constant moisture exposure, as much as anything else.

I doubt that one exposure to galvanized would do much harm, as long as it isn't long term.

I have same problem. I used to have wood chips under my stored equipment until the chips decayed and weeds came. I'm looking for used carpet. Plan to put it down upside down on ground, put equipment on top. I'm thinking carpet will prevent weeds from growing longer than roundup will.
 
2-4D won't touch any grass, unless put on way to heavy.
Glyphosate won't bother metal, that I know of. Now is you add AMS like a person should, it will cause rust.
 
No Myron we have hand wand plugs of all the spray rigs to just plug on a hand wan on the was outs..
 
I use old carpet too. free
turn it over every year or 2 because your tractor tires will bring dirt in on it and stuff will grow.
(watch for tacks on pulled up old carpet)
Implement parking area is also a good spot to dump all the old calcium out of tires.
kills most everything, and discourages new growth for some time.
 
Don't know if it will cause more corrosion but I used to spray my scrap pile and after many rains over a long time, I could smell the herbicide when burning or welding items from pile.
I am sure it did not penetrate the metal but couldn't understand why it didn't wash off.
Something else to consider:
Many years ago, I sprayed Roundup at 2 oz. per gallon =50 gal. along an old fence. After about two weeks, there was just a small amount of kill.
I called the Auburn Extension Service and was told that I should not have sprayed in drought conditions! It had not rained in MANY weeks and it was definitely drought condition.
I waited until it rained and two days later, I sprayed another 50 gallon mix and in one to two weeks, everything was dead.
I learned a valuable lesson although the instructions clearly stated to not spray in drought conditions!
