An analysis in the framework of the radiation-dominated era permits to put bounds on the weak modification of general relativity which arises from the Lagrangian R1+ε. Such a theory has been recently discussed in various papers in the literature. The new bounds together with previous ones in the literature rule out this theory in an ultimate way.
