Using Garlic extract in horticulture

Garlic has so much more potential than just being a culinary delight and I feel there have been great advances in its use as a horticultural insecticide and fungicide.


During my time as Marketing Manager for Weed Free, I looked in to the commercial viability of Garlic extract as a worm repellent on sports turf - principally golf greens - but my research (about two years ago) came to a halt because it was soon apparent that cost of the material was just too high to use commercially.


I think things have moved on and I was wondering, if there were commercially available garlic products available to trade users, would LJN members use them?

    Hi Phil, I think like everything, it would come down to price and performance of the product against current market ones
  • It could be a useful addition to the arsenal. Especially for use in allotments and organic regimes.

     

    To touch on the subject of price, I remember reading on an allotments forum a while back that like with rhubarb leaves, the green tops of garlic can be boiled in water to make a useful insecticide. Perhaps if this was a waste product of garlic harvesting it may be cost effective?

    I've spoken to Hugh Struth of Aston Horticulture today and I'm hoping to get a bit of information on this shortly.

    When I looked into garlic for the control of worms on golf greens it was prohibitive but Hugh says his products could be cost effective.

  • We've used a garlic potion to keep slugs off our Hostas in the past (it was shown on Gardeners World a few years ago).   It worked, but was very smelly, and washed off very easily, so had to be re-applied very frequently.

     

    I think it would be a good organic product if it could be made to stick better, and if the smell could be moderated!
