The best rod for worm fishing is a combination of rod action, line weight, and length. In general, the best power is medium-light.  The best-rated rods for this application have IM7 graphite construction with full-composite bonding to increase strength and sensitivity. Combinations of graphite with fiberglass give a great balance between casting distances and sensitivity to detect that bite. Oversized guides reduce wire resistance from wind effects on long casts used in big water environments where casts often exceed 180 degrees before detecting bottom contact.  Overall, We would probably say that a good rod for plastic worm fishing would be a medium to medium-heavy fast action tip rod in 6'6'' to 7' length.
