This could have important consequences for pollination, with negative impacts on the natural world, researchers say.
Bumblebees are less likely to land on flowers sprayed with fertilisers because of certain changes associated with the chemicals, experts have said.
Dr Ellard Hunting, of the University of Bristol’s School of Biological Sciences – who is the lead author on the paper, said: “We know that chemicals are toxic, but we know little about how they affect the immediate interaction between plants and pollinators.“Flowers have a range of cues that attract bees to promote feeding and pollination.
For the study, the researchers investigated the effect of fertilisers commercially available in the UK on different types of floral cues used by bees. A similar effect was also seen when the researchers sprayed the lavenders with a pesticide known as imidacloprid, which is banned for outdoor use in the UK and the European Union, but still used in the US and a hundred other countries.
