Assistant manager Steve Fletcher struck late to give Bournemouth manager Lee Bradbury a winning start in his first game since being made Eddie Howe's permanent successor in a 2-1 win at Plymouth.
Fletcher came off the bench and fired home to continue the south-coast side's quest for back-to-back promotions after Rory Fallon's second-half strike had looked likely to earn hard-up Argyle a point.
They had found the Cherries' Iraq-born goalkeeper Shwan Jalal almost impassable after Marc Pugh had put the visitors ahead.
Fallon's first goal since returning from a loan spell at Ipswich made amends for his wasted opportunity immediately before Bournemouth opened the scoring.
It came when Pugh reacted smartly after Danny Ings' shot had crashed back off the Argyle crossbar to fire a low shot inside goalkeeper David Button.
The Pilgrims rallied, but Jalal was in devastating form. The 27-year-old Iraqi parried a drive from Yala Bolasie, before stopping shots from Marcel Seip and Patterson.
The second half saw a similar pattern and Argyle should have equalised when Zubar's cross was headed by Kari Arnason into the path of Patterson.
However, the Northern Ireland international blazed his shot from three yards over Jalal's crossbar.
Argyle eventually got their reward when Jim Paterson drove in a shot that hit the post, with Fallon bundling the rebound over the goal-line.
