Farmer spraying glyphosate onto property.

Has any grass or plants on your property died.

If not it's unlikely any glycophoshate made it onto your property and so there should be no risk to the health of you and your family.

Also have you spoken to the farmer, if not he could have been spraying something other than glycophosphate, perhaps even an organic fertiliser.

Unlike the local person you mentioned, this spraying person did not ring the op to say when and what he was spraying. So it's fair for a non farmer to assume its glyphosate as oppose to sprayable fertileser, which is a relatively new system.

I cant answer you op, as I'm not up on the tillage farming, but you've asked in a nice way what to expect, and I hope you get genuine answers, with out other farmers jumping down your throat.

Nobody can be sure what this person is doing anyway, so tracking down the landuser is the only sure way of finding out.

Maybe a photo of the field he was spraying might help us establish what he was spraying, and what he was likely to be spraying on it.

Unlikely to have been glyphosate I'd think. Glyphosate is only sprayed on some plant you wish to kill immediately.

It kills by dessication ie: drying the plant out (it is basically a salt type product) so, yes it's sometimes used on cereals right before harvest in order to get a drier grain. Also occasionally on silage if the field is being reseeded afterwards and it causes the dry matter% of the silage to be higher.

Personally i disagree strongly with using it on food for people or animals but there you go, - it's not illegal and some people do it.

It would kill all grass along the margins of the field and if it blew into your site, - possibly your lawn plants or grass.

As others said, try to find out who the farmer is and ask him politely what he sprays and if it could affect your health or property. That will mark his card without causing an argument and he might give your side a miss next time.

More likely to have been some other product anyway, either sprayable seaweed fertilizer or an anti-fungal or something.

First thing I'll say is the thread title is pretty damning and a serious allegation, which it turns out is most likely horseshit.

Unlikly to be glyphosphate. If it's oilseed, most likely now it's fertiliser. It's blooming now and soon will cover over and stop weeds growing well. Could also be some fung/herb/insect icide. Previous poster suggests getting onto twitter which is a good shout. And no harm either to ask the farmer the next time they are in the field. Explain your concern and don't whatever ya do go ranting about him/her killing you and your family with sprays. Just ask what it is, how often is it happening and if possible could he notify you in advance so ya can shut windows, etc.

Next time you see someone in the field go to the gate and get their attention. Don't enter the field until they stop, they'll either come to you or signal for you to come to them. Then explain that you live next to the field and ask what they are spraying.

There most likely will be more spraying and as farming is 100% weather dependent it could be at anytime of the day or night.

Edit... Depending on the size and layout of the field they may not be able to stop until they finish the field. So wait till the are on the last few rows.

Why do you not talk directly to the land owner?

You will get a more accurate response from him or her, here you will get speculation and scaremongering.

I can tell you you will know in 10 days if it was the chemical you use in the title and if I crossed onto your plants in any measurable or effective quantity, the plants will turn brown and die.

Harsh now. Anyone can ask questions

A herbicide is a pesticide, as is e.g. an insecticide and a fungicide. Pesticide - the generic name.

But hardly relevant to OP's (legitimate) concerns.

It entirely possible it's glyphosate. It's used extensively on tillage crops including rapeseed.

It doesn't "kill by dessication"; it inhibits proteins in some way and hence growth.

It is used as a dessicant which is a secondary purpose which was never it's initial intended purpose. This has let to a huge increase in the application of glyphate in recent decades especially in damper, e.g. more northern climes.

It is a salt but it's nothing like a "basic salt".

Not at this time of year.

Glyphosate is only sprayed on tillage crops before harvest. It’s 2-3 months too early for a tillage man to be using glyphosate on his crops.

If it’s winter oilseed rape then early April would be the timing for a fungicide spray. It may need another application in 4-5 weeks time depending on what is present on the crop and on how long it stays in flower for.

If it turns out that it is glyphosate that has been used then an angry neighbour is the very least of that tillage man’s worries.
