Lawn weedkiller and veg

I applied lawn weedkiller containing clopyralid etc, but used the green watering cans, not the red. Oops. So I washed them out, then watered veg plants. Some young carrots are showing curling after one day, peppers are drooping. I assumed diluting the stuff by 1/1000 or more by washing would neutralise it. Nope. 3 parts per billion affects major groups such as solanaceae e.g. peppers. Oh hell. I suppose I'll find out soon if they are done for. Are my beans has beans? Are my peppers in a pickle? 

This stuff is really toxic to peppers, toms, beans, carrots, parsnips. Does anyone grow veg and use verdone etc? If not, how do you control lawn weeds? Or are you all hippies who hug bees, and wear organic socks?

    I have a friendly relationship with the wildflowers in my lawn and yes, I hug treesimage

    Are you colour blind? Not being facetious but red/green colour blindness is a very common condition especially in men which has made me wonder about the wisdom of those colour choices for watering cans.

    Why is that Verdun?  My most prolific crop in my garden at the moment is bindweed, followed closely by couch grass.  Why can't I stir fry that up and serve it to my family? Why all the careful molly-coddling of the most temperamental ornery difficult plants?  That seem prone to death at every turn.. and after months of protection and battle against pest, disease, and elements.. may -or may not- provide us with a delicious feast.  Mother nature has a wry sense of humor.

  • I don't use commercial weedkillers. They have too many chemicals and most of them are really dangerous. If you knew exactly what they contain and how bad it is, you won't spraying it on your plants. I make my own weed killing spray, just like the one here: . You can try using it and next time you won't mix the cans and your veggies won't suffer damage.

    No, I am not colour blind, I made a mistake even though I purposefully have red and green watering cans. I also thought lawn weedkiller was as per glyphosate. A good wash and the can is clean. Not so.

    Actually bindweed roots are edible, apparently, although they act as a laxative. Dandelion leaves and roots are edible.

    As an aside, I took the last lot of weedkiller contaminated lawn cuttings to the local tip and they said put them in the green bin (for composting). I said I wouldn't, explaining why, and he got quite stroppy, and walked off. I put them in the general waste. So, it looks as if municipal compost, which goes into most commercial compost apparently, may contain clopyramid etc.

    Where did you expect to put the contaminated grass cuttings? Tips can't provide bins for every permutation. If you don't think they should go in the composting bin, don't take them to the tip.

    That's one of the reasons I never by local authority compost.

    Actually they do provide a wide range of bins for waste oil, rubble, metal, wood, green waste and many others. Many people put out garden waste for collection, and I reckon most weedkiller sprayed grass clippings go into those bins. 

    There is little information online, but one source suggests aminopyralid, clopyralid etc are broken down by hot composting. I found nothing on this at our waste site page. Clippings are not banned. There has in the past been an issue with contamination of compost by weedkiller, here and in the US. 

    And I do wonder about absorption by tree roots under the lawn, especially with saplings.
