Plants combat plants - cannons

Question: when is a cannon not a cannon? Answer: when it’s a ‘high-pressure long-range deodorant spray’(!). For such is the description of the cannons currently being deployed in China to combat the malodorous odours emanating from a Beijing rubbish dump ( Over 100 of the odour-busting devices have been recruited to defend the city’s inhabitants from the offensive smells that issue forth from the Gaóantun landfill site. In a nice twist the offending odour – due in no small measure to decaying plant matter – is being neutralised by dousing with a spray made from… plant extracts. But, try as I might, I could not sniff out the precise formulation of this mixture for you.

I am a Botanist and former Senior Lecturer in Botany at Bath Spa University (Bath, near Bristol, UK). As News Editor for the Annals of Botany I contributed the monthly Plant Cuttings column to that international plant science journal for almost 10 years. As a freelance plant science communicator I continue to share my Cuttingsesque items - and appraisals of books with a plant focus - with a plant-curious audience at Plant Cuttings [] (and formerly at Botany One []). In that guise my main goal is to inform (hopefully, in an educational, and entertaining way) others about plants and plant-people interactions, and thereby improve humankind's botanical literacy. I'm happy to be contacted to discuss potential writing - or talking - projects and opportunities.
