Resolva weedkiller sprayed near vegetables...time to dispose?

I’ve been growing tomatoes, spring onions, radishes, carrots and courgettes in pots this year on the patio. It had all been going nicely. The courgettes have nearly finished but there are plenty of ripe tomatoes I’ve been picking daily and a couple of pots of spring onions I’d been saving to use. The carrots and radishes were late sown so still not ready. Unfortunately I just found out that someone else in the household has sprayed resolva weedkiller over the drive this weekend, completely unaware of any harm it could do to the plants. So, my guess is, not knowing how close the weedkiller got to the tomatoes and spring onions, I should just pull them all up now?

    Maybe a bit late now but I'd have washed them all down immediately with the hose so it couldn't be absorbed.   It contains glyphosate so not something I'd want to eat.

    Thanks for replying, I had a feeling this would be the case :( unfortunately I just found out this morning so as you say, probably too late to do anything about it now. Far worse things happen I know, but pretty gutted.

    Have a gentle chat with the culprit about weed killers not knowing the difference between weeds and wanted plants so consult first and take extreme care to protect plants, especially edibles.

    Do bear in mind that farmers use glyphosphate on their cereal crops before harvest - unless you buy organic

    Knowledge is knowing that a tomato is a fruit.
    Wisdom is not putting it in a fruit salad.

    Good idea, I did mention it to them and felt bad in doing so as I knew it was unintentional but just wanted to make them aware - they were very apologetic and genuinely had no idea of the effects of the weedkiller.  Would the compost in the pots be ok to reuse next year? From what I’ve read the chemicals supposedly don’t last long in the soil but then I saw another article which says it could last up to a year...would you err on the side of caution and replace?
  • Just how close is your veg to the driveway?  If it was a still day and the veg weren't actually touched by the spray, you may be lucky.
    You should soon see if the veg show signs of dying back ?
    Horribly bad luck tho but maybe you can save some.
    Pop the culprit in the dog kennel for a day or 2  ;)  

    Thanks for replying, at the point nearest to the drive, the vegetables were about a metre away (the patio is raised about a foot from the drive) and at the furthest point I’d say about three or four metres). It was unfortunately mildly breezy so I expect there was at least some drift.

    That’s interesting, I didn’t know it was used in this way.

    I would see if the veg are still in rude health, then take a view. If there was no sign of problems in a couple of weeks I would be relatively sanguine. Farmers are able to use it within 2-3 weeks of harvesting as a desiccant, so that seems reasonable to me. I think I would be more confident in the root crops if forced to choose.

    I would think reusing compost would be fine, as afaik it is designed not to persist significantly in the soil

    I have next door's ivy invading my garden like the Mongolian Horde over and *through* the stone wall, and I keep buying it rounds of glyphosate like a lawyer in Ye Olde Mitre in Ely Place supping lager. Neighbour has no problems. I hope to have nearly won with 3 applications this year so I can in due course put fruit cordons on the wall.

    Nor am I aware of any convincing evidence that it is a health issue. Various political muggings and panics, and also use in scare marketing for the organic principle - but I have seen no evidence yet.

    My opinion obvs.

    Wait a couple of weeks and see how the plants are.  You'll be able to tell if they're affected or not.

    Monsanto claim that glyphosate becomes inert upon contact with the soil and that it is harmless to humans.  Unfortunately for them there are enough studies which show that glyphosate filters thru into waterways and can affect aquatic life and vegetation.   There are also studies which show that used in higher concentrations - eg where sprayed on Monsanto GM crops designed to be resistant so you can spray weeds with higher concentrations - glyphosate can harm human health.

    That is why it is now a controlled substance here in France, not available for personal/private use since Jan 2019 and banned for use in public spaces since 2017.
