Two goals in each half were enough to see Argyle ease to the victory that leaves them on the brink of securing a fifth-placed finish in the EFL Youth Alliance League.
In regular circumstances, fifth place would have meant the young Pilgrims competing in the Merit League One for the first time in three years, but the coronavirus pandemic has seen the competition altered to reduce travelling.
Argyle will now be competing in a league that consists of Bristol Rovers, Cheltenham Town, Exeter City, Forest Green Rovers, Newport County and Yeovil Town in a mini league of three home and three away fixtures.
This result was never really in doubt as Argyle dominated from start to finish, and should have really led by more than two goals at the break.
They opened their account on 10 minutes after good work by Rhys Shirley saw him cut in from the left, before being bundled over for a penalty which he converted with composure.
It was on the half hour that Shirley's shot rebounded to Will Jenkins-Davies, who gleefully rammed the ball home from close range.
The second half was 20 minutes old when wing-back Oscar Rutherford’s cross was headed back across goal by substitute Jack Endacott, for Shirley to apply the finish.
The scoring was completed 10 minutes later when substitute Jeffery Forkuo slotted a great ball through to Jamal Salawu, and he calmly fired low past the advancing goalkeeper.
Argyle: Tyler Coombes, Oscar Rutherford, Oscar Halls, Ethan Mitchell, Brandon Pursall (Ali Mansaray 82), Jamal Salawu, Carlo Garside (Charlie Miller 60), Angel Waruih (Jeffery Forkuo 70), Will Jenkins-Davies, Oscar Massey (Jack Endacott 60), Rhys Shirley. Substitute not used: Lewis Moyle.
