CABI scientists are leading the fight to control one of the UK’s most invasive weeds – Himalayan balsam
CABI experts in the field of classical biological control are leading the fight to manage one of the UK’s most invasive weeds -Himalayan balsam – thanks to the nationwide release of the rust fungus Puccinia komarovii var. glanduliferae.
Himalayan balsam has rapidly become one of the UK’s most invasive weed species. A lack of natural enemies allows it to successfully compete with native plants for space, light, nutrients and pollinators, reducing biodiversity and contributing to erosion. Traditional control methods are inadequate. This project involves identifying an insect or plant pathogen that exclusively attacks Himalayan balsam, which can be released into the UK to control the plant while leaving indigenous species intact.
