The General Assembly of IRS proclaimed in 2011 that the first Saturday of the summer will be The International Ragweed Day (IRD) to increase understanding and awareness of the problem this invasive weed causes all over the world.
The day was chosen because it is early in the growing season of the plant thereby gives enough time for preparations and actions.
This year, the International Ragweed Day will be observed on June 20th, 2020.
