Ethylene diurea (EDU) is a chemical compound with the formula C4H10N4O2. It has been analyzed by several groups to determine whether it is a successful antiozonant. If so, this substance would help crops by preventing the harmful effects on crops by ozone. In an experiment run in 2002 by a group called Alberta Environment (now known as Alberta Environment and Sustainable Resource Development, they determined that EDU did one of two things. The substance either prevented the harmful effects of ozone or it stimulated plant growth.
