Lavender Oil As An Herbacide

Scientists have known for decades that many essential oils have antimicrobial properties and at least some potential for use as fungicides and pesticides in fields and commercial gardens. Now researchers are looking at lavender oil as a potential herbicide as well.

Italian scientists at the National Institute of Health and Safety found that compounds in lavender oil were effective at killing certain types of weeds, even in very low concentrations. This is good news for a couple of reasons.

First, volatile organic oils may have far fewer health risks associated with them than synthetic pesticides and herbicides. Second, volatile oils are produced from sustainable crops with a low impact on the environment.

And, of course, because essential oils degrade so readily in the environment, there’s a much smaller chance of them accumulating in the soil and adding to the existing chemical load in the world’s croplands.
