Racing from lane six in heat two Rodger came home in a time 50.71secs - outside his personal best of 49.19secs.
South African Cornel Fredricks finished first and qualified for the final in a time of 49.26 narrowly ahead of Jeffery Gibson from the Bahammas 49.66.
Rodger initially finished sixth but was bumped up to fourth after two athletes were disqualified. It was not enough however to force his way into the final.
It was a huge blow for the 23-year-old European under-23 silver medallist who reached the final of the World Championships held in Moscow last year.
Prior to the race, Rodger had said he was in good shape despite recovering from whiplash injuries following a recent car crash.
After the race he tweeted, “So disappointed with today’s performance, thank you for all your support, sorry to let everyone down! I promise I will be back stronger.”
Jehue Gordon (49.29), Annsert Whyte (49.48), Christian Cuevas-Morton (49.62), Roxroy Cato (49.51), Boniface Mucheru (49.67) and England’s Richard Yates were the other qualifiers from Friday’s final.

“The support’s been amazing here, absolutely brilliant.”
