Tomato roots as weedkiller

One of my old-fashioned gardening books says you could use an extract of tomato roots as an organic weedkiller. Has anyone ever tried it? And how do I make an extract of tomato roots???

    I am fairly certain that this is not true, seeing as at the end of the season, most of us compost our tomato plants, with no adverse effects.

  • The book says that, to surpress weeds, mainlty couch grass, you could better plant tomatoes or spray with an extract of their roots then use a chemical weedkiller. It would be a pity if it didn't work, because it would be very cheapimage

    I could see it as an insecticide, but not a herbicide?

    I can confirm that the extract of the leaves works pretty well as a pesticide... but as a herbicide seems very doubtful.
